Description

MIXING VALVE
BACKGROUND AND SUMMARY OF THE INVENTION
The present invention relates generally to fluid control valves and, more particularly, to a mixing valve for use within a faucet.
Single-handle water faucet control valves are well known in the art and have been offered with different mechanical structures for controlling the available directions of travel, the ranges of motion, and the type or style of motion for the handle. One such known style of control valve includes a handle that is moved in a generally sideways (left-to-right and right-to-left) direction in order to adjust the mix of hot and cold water for a desired temperature. With this style of water faucet valve control arrangement, the handle is typically moved in an upward or forward direction, away from the user, to increase the flow rate and the volutne of water delivered. The handle is typically moved in a downward or rearward direction, toward the user, in order to reduce the flow rate and volume of water, or to completely shut off the flow of water delivered from the faucet.
Known single-handled control valves are often referred to as having a joy stick control handle due to the single-handle construction and the manner in which the handle may be moved. The directions and ranges of motion are controlled by the internal structure of the valve mechanism and by the selection and arrangement of the component parts. It is further known to provide a water faucet control valve that is constructed and arranged to independently control the temperature and the flow rate of the water delivered to a use location by a single-handle or control lever.
Illustrative examples of single-handled faucet control valves are described in U.S. Patent No.
6,920,899, and U.S. Patent Application Serial No. 11/444,228, filed May 31, 2006.
One illustrative embodiment of the present invention includes a valve assembly for controlling water flow in a faucet, the valve assembly including a valve body having hot and cold water inlets and an outlet. A lower disc includes first, second, and third ports corresponding to the hot and cold water inlets and the outlet, and is supported by the valve body. An upper disc includes upper and lower surfaces, the lower surface being positioned in engagement with the lower disc and including a peripheral channel for selective communication with the first, second, and third ports.

In this illustrative embodiment, valves 90 are constructed of rubber and provide a biasing force between the lower surface of valve body 34 and lower disc 72. Seals 90 may be of the type detailed on U.S. Patent Application Serial No. 11/444,228, filed May 31, 2006, which has been expressly incorporated by reference herein. Valve body 34 includes a pair of notches 35 conflgtued to accept tabs 44 extending from upper housing 38 to prevent rotation of upper housing 38 relative to valve body 34. Valve body 34 also includes external threads 37 configured to interact with internal threads 39 (Fig. 10) on the interior surface of bonnet nut 28 to secure bonnet nut 28 to valve body 34.
Referring further to Fig. 5, when valve assembly 24 is coupled to hot and cold water supply conduits 20 and 22, a pressure reducing hydrobalance is created between carrier 62 and upper disc 68. Aperture 70 in upper disc 68 allows water from channel 77 to flow between carrier 62 and the upper surface 68a of upper disc 68.
Openings 67 of carrier 62 may also be supplied with water supplied from aperture 70. In the illustrative embodiment, the area of upper surface 68a of upper disc 68 defined within 0-ring 66, which is positioned in groove 63 of carrier 62, is greater than the collective cross-sectional area of seals 90a and 90b, which are positioned between the lower surface of lower disc 72 and valve body 34. In other words, the water pressure between carrier 62 and upper disc 68 has a greater surface area on which to act than that of water pressure acting on seals 90a and 90b. Therefore, the water pressure creates a net downward force on the upper surface 68a of upper disc 68 to minimize any leakage between upper disc 68 and lower disc 72.
Referring now to Fig. 10, a cross-sectional view of valve assembly 24 is shown. As discussed above, interior ridge 31 of bonnet nut 28 contacts shoulder portion 48 of 48 of upper housing 38 to provide a compressive force on upper housing 38. Additionally, flange 40 is positioned between bonnet nut 28 and valve body 34 to prevent corrosion and provide a biasing force between bonnet nut 28 and valve body 34. Tabs 42 of upper housing 38 interact with notches 41 of aperture 60 in coupling member 50 to couple coupling member 50 to upper housing 38. Longitudinal ....A. SI e- .....

extension 29 extends through opening 53 in coupling number 50 into aperture 64 in carrier 62. Projections 65 extend into depressions 69 in the upper surface of upper disc 68, As discussed above, the diameters of carrier 62 and upper disc 68 arc substantially smaller than the diameter of lower disc 72.
As further shown in Fig. 10, carrier 62 andlower disc 68 are moved by longitudinal extension 29 of stem assembly 23 to selectively adjust the temperature and the flowrate of water supplied by valve assembly 24. As discussed above, one of the seals 90e is positioned in outlet bore 95 of valve body 34. Outlet borc 95 opens into radially extending outlet bore 36 in valve body 34. As detailed herein, seal 90e directly contacts the lower surface of lower disc 72 around outlet port 78.
Outlet bore 36 is also in communication with axially extending outlet bore 92 of valve body 34.
Bore 92 may be coupled to spout 16 or to an accessory.supply line which may be used for a hand sprayer or any other suitable fluid delivery device.
Referring now to Figs. 10-12, valve assembly 24 is shown with stern 26 pivoted or oriented to place the internal components of valve assembly 24 in the partially open position. When stem 26 is in this orientation, an equal amount of hot and cold water is allowed to pass through hot and cold water inlets 76a and 76b to outlet port 78. Referring specifically to Figs. I I and 12, in this orientation, channel 77 and the lower surface 68b of upper disc 68 are positioned over a small portion of = each of the hot and cold water inlet ports 76a and 76b. In othcr words, the inner = channel cdgc 73a partially overlaps the outer control edges 85 of the inlet ports 76a and 76b. Central portion 73 of upper disc 68 is covering a significant portion of inlet = - . ports 76a and 76b. As water enters channel 77 through inlet hot and cold water inlet ports 76a and 76b, it fills channel 77, mixes to create "warm" water, and exits through outlet 78, which is substantially open to channel 77. The "warm" water then moves through outlet port 78 and seal 90-to outlet bore 95 and spout 16 as shown in Fig. 1.
Referring now to Figs. 13-15, stem 26 has been pivoted forward to a different orientation such that inlet ports 76E and 76b are substantially uncovered or unblocked .
by central portion 73 of upper disc 68. In other words, there is a substantial overlap between the inner channel edge 73a and the outer control edges 85 of the inlet ports 76a and 76b. A greater amount of hot and cold water is allowed to fill channel 77, = mix to create "warm" water, and cxit through outlet port 78. The water then exits valve assembly 24 through outlet bore 95 as discussed above. In each of these two AMENDED SHEET - WE:A/US

amount of water will exit valve assembly 24. In Figs. 13-15, a "full flow," or maxinnun flowrate of water, will exit valve assembly 24.
Referring now to Figs. 16-18, stem 26 is shown pivoted in a rearward direction to the fully or completely closed orientation. In this orientation, valve assembly 24 will be closed (i.e., no water will flow through valve assembly 24).
Scallop or convergence 46a of aperture 46 (Fig. 2) cooperates with longitudinal extension 29 of stem assembly 23 to provide a detent of stem assembly 23 when in the completely closed or zero position. As shown in Figs. 16 and 18, central portion 73 of upper disc 68 completely covers or blocks hot and cold water inlet ports 76a and 76b to prevent water from filling channel 77 and exiting through outlet port 78. Even if water were to leak through either inlet ports 76a and 76b to channel 77, the water would exit channel 77 through outlet 78 to create a drip or small stream, for example, through the spout of the faucet assembly including valve assembly 24. In this manner, channel 77 prevents water leaks in the valve assembly 24 from leaking through the valve assembly to the faucet base 12 or under the faucet 10, which may cause corrosion around the faucet base 12 or handle 14 of the faucet 10. If any leakage were to occur in valve assembly 24 as a result of damage to discs 68 and 72 adjacent ports 76a, 76b, 78, the water leaked would exit valve assembly 24 through outlet bore 95 and any attached spout 16 or accessory rather than around the base 12 of the faucet 10.
Figs. 19 and 20 illustrate the stem 26 orientation and the corresponding position of upper disc 68 when the operator desires only cold water from valve assembly 24. As shown, when stem 26 is positioned in this orientation, central portion 73 of upper disc 68 completely covers or blocks hot water inlet port 76a and completely uncovers or unblocks the cold water inlet port 76b, allowing the water from the uncovered port 76b to flow through channel 77 to outlet port 78.
Conversely, in Figs. 22 and 23, the stem 26 orientation shown opens the opposite port 76a (i.e., allows the user to select completely hot water flow). As shown, in this orientation, central portion 73 of upper disc 68 completely covers or blocks the previously uncovered cold water inlet port 76b and completely opens the previously covered hot water inlet port 76a to allow hot water to fill channel 77 and exit through outlet port 78.

13.1)D1101 .34115673v1 AMENDED S F. F.' I - I P EA/us Another illustrative embodiment of valve assembly 24 is shown in Figs.
23-26. Referring now to Figs. 23 and 24, valve assembly 110 includes bonnet nut 112, upper housing 116, stem assembly 120, coupling member 130, carrier 132, upper disc 138, lower disc 144, upper seal 150, lower housing 152, lower seal 154, and valve body 158. Valve assembly 110 is similar to valve assembly 24 shown in the previous embodiment, however valve assembly 110 includes two opposing sealing surfaces instead of the single sealing surface defined by seals 90 in valve assembly 24. In this embodiment, carrier 132 includes interior wall 134 and downward extending projection 136, which interacts with notch 142 in upper disc 138.
Upper disc 138 also includes opening 140 which is configured to accept interior wall 134 of carrier 132. Longitudinal extension 129 of stem assembly 120 extends through coupling member 130 and into interior wall 134 of carrier 132 to actuate carrier 132 and upper disc 138.
Referring now to Figs. 25 and 26, lower disc 144 includes hot and cold water inlet ports 146a and 146b and outlet port 148. The lower surface of lower disc includes channel 145 extending around inlet ports 146a and 146b and outlet port 148.
Seal 150 is positioned in channel 145 and corresponds to channel 151 in the upper surface of lower housing 152 as shown in Fig. 26. The lower housing 152 includes channel 153 extending around inlet apertures 151 and outlet aperture 155.
Channel 153 corresponds to seal 154 which is positioned in channel 153 to provide a seal against the interior lower surface of valve body 158. Valve body 158 includes inlet bores 160 and outlet bore 162 which are configured to couple to hot and cold water inlet supply lines and an outlet supply line. In this embodiment, valve assembly 110 includes two sealing surfaces 150 and 154 compared to the single layer of sealing surfaces formed by seals 90 between lower disc 72 and the interior lower surface of valve body 34 of valve assembly 24 shown in Figs. 2-22.
A further illustrative embodiment valve assembly 210 is shown in Figs. =
27-38D. While not shown, bonnet nut 28 and valve body 34 similar to those detailed above may be utilized to receive the internal valve components of valve assembly 210. Valve assembly 210 includes upper housing 216, temperature limiting member 218, stem assembly 220, coupling member 230, carrier 232, upper disc 238, lower disc 244, upper seal 250, lower housing 252, and lower seal 254. Carrier 232, upper disc 238, and lower disc 244, may be similar to carrier 132, upper disc 138, and lower disc 144, as detailed above. Likewise, seals 250 and 254 may be similar to seals 150 and 154, as detailed above in connection with valve assembly 110.
Furthermore, as with valve assembly 110, upper disc 238 may include opening 140 which is configured to receive interior wall 134 of carrier 232. Also, lower disc 244 includes hot and cold water inlet ports 146a and 146b and outlet port 148.
As shown in Fig. 28, stem assembly 220 includes a ball 225 which receives a stem 226. As shown in Figs. 28 and 31, stem 226 may be substantially L-shaped and include upwardly extending leg 228a and laterally extending leg 228b. Ball 225 may be molded from a thermoplastic material over a portion of stem 226, such that leg 228b defines a support for a lateral extension 227. A longitudinal extension or knuckle 229 extends downwardly from the ball 225 generally opposite leg 228a of the stem 226. In a manner similar to that detailed above, ball 225 transmits motion of stem 226 to upper disc 238 through extension 229 and carrier 232.
With reference to Figs. 28 and 32, coupling member 230 includes diametrically opposed tabs 256 extending downwardly from a circular base 258.
Tabs 256 are configured to be received within notches 260 formed within lower housing 252 to facilitate proper angular orientation between coupling member 230 and lower housing 252 and prevent relative rotation therebetween. A pair of diametrically opposed notches 262 are formed within an outer edge of base 258 and are configured to receive locking extensions or loops 264 of upper housing 216. A pair of diametrically opposed recesses 266 extend downwardly from an upper surface 268 of base 258 and are configured to receive tabs 270 of upper housing 216, thereby facilitating proper angular orientation between upper housing 216 and coupling member 230. An upwardly extending cylindrical wall 272 is coupled to base 258 and forms a cavity 274 having an arcuate surface 276. An opening 278 formed within wall 272 is configured to receive extension 227 of stem assembly 220. Ball 225 of stem assembly 220 is configured to contact arcuate surface 276 of coupling member 230 in a manner similar to that detailed above with respect to valve assembly 24.
Aperture 280 is positioned at the bottom of cavity 224 and is configured to receive extension 229 of stem assembly 220 which, in turn, engages carrier 232.
With reference to Figs. 28 and 34, temperature limiting member 218 is received intermediate coupling member 230 and upper housing 216. Temperature limiting member 218 includes a cylindrical body portion 282 and a pair of downwardly extending biasing members, illustratively flexible arms 284. The flexible arms 284 have a lower contact surface 286 configured to slide along a glide surface defined by the upper surface 268 of base 258 of coupling member 230.
Body portion 282 includes a cylindrical wall 286 having an upper surface 288 supporting a plurality of indexing members, illustratively teeth 290. An indicator 292 extends upwardly above the teeth 290. Wall 286 of cylindrical body portion 282 includes a downwardly facing inclined surface 294. As explained herein, inclined surface cooperates with lateral extension 227 of stem assembly 220 to limit the lateral pivoting motion of stem 226 and extension 229 (i.e., relative to inlet ports 146a and 146b), and hence the maximum allowable temperature of water flowing through the valve assembly 210.
Referring now to Figs. 28, 29, 31, and 33, upper housing 216 includes a cylindrical outer wall 296 and a cylindrical inner wall 298. Walls 296 and 298 are concentric, thereby defining a channel 300 therebetween. An upper portion of wall 286 of temperature limiting member 218 is supported for movement within channel 300. A rim 302 extends radially outwardly from outer wall 296. Downwardly extending loops 264 are supported by rim 302 and are configured to cooperate with notches 262 formed in the coupling member 230, and with latches or tabs 304 formed within lower housing 252 (Fig. 28). More particularly, the loops 264 are received within recesses 306 surrounding the latches 304. Each latch 304 includes an inclined or ramp surface 308 and a retaining surface 310 configured to cooperate with an inner surface 312 of the respective loop 264. Outer wall 296 includes a receiving channel or slot 314 configured to receive the lateral extension 227 of the stem assembly 220.
As shown in Figs. 31 and 33, a plurality of indexing members, illustratively teeth 316, extend downwardly from an upper member 318 of upper housing 216 and are configured to cooperate with teeth 290 of temperature limit device 218. An arcuate slot 320 is formed within upper member 318 of upper housing 216 and is configured to receive indicator 292. An opening 322 similar to opening 46 of previously described upper housing member 38 is formed within upper member 318.
Pivoting movement of stem assembly 220 about axis 324 of lateral extension 227 controls the flow rate of water, while pivoting movement of stem assembly about an axis 326, perpendicular to axis 324 of lateral extension 227 and stem 226, controls the temperature of water supplied by valve assembly 210. The inclined W() 2008/013715 surface 294 of the temperature limiting member 218 controls the amount of pivoting movement of the stem assembly 220 about axis 326. As further detailed below, rotation of the temperature limiting member 218 about its center axis 328 limits the motion permitted of stem assembly 220 about axis 328.
As detailed herein, stem assembly 220 includes ball 225 that transmits stem motion to upper disc 238 through extension 229. Ball 225 allows spherical rotation, while preventing lateral motion. Since valve assembly 210 only requires two degrees of freedom (temperature and volume), rotation about stem assembly 220 is prevented by operation of lateral extension 227 coupled to ball 225 that rides in the slot 314 in cooperating upper housing 216.
Lateral extension 227 has two motions in slot 314. The first motion is a pivot motion about its own axis 324. The second motion is a pivot motion about axis 326, which is substantially vertical, within slot 314, and which has a constant radius from the center of the ban 225. Through orientation of slot 314, these two motions may correspond directly to temperature and volume motion of valve disc 218.
While the pivoting movement of stem assembly 220 of valve assembly 210 is similar to the pivoting movement of stem assembly 120 of valve assembly 110 (Fig.
23), the extension 227 of stem assembly 220 is offset by 90 from extensions 27 of stem assembly 120. If the extension 227 is located in a side-to-side orientation relative to inlet ports 146a and 146b (Fig. 28), as opposed to a front-to-back orientation relative to inlet ports 146a and 146b and outlet port 148 (Fig.
23), the temperature will be directly related to the motion of the extension 227 in the slot 314.
The flow rate control motion will translate to the rotation of the extension 227 about its own axis 324. As such, to limit the maximum temperature, the travel of extension 227 within the slot 314 is reduced or limited. The limiting member 218 includes inclined surface 294 that engages extension 227 on the ball 225. As the temperature limiting member 218 is rotated about axis 328 of the valve assembly 210, the point of inclined surface 294 that is engageable with the extension 227 is set at different heights and, thereby, limits the travel of the extension 227 in the slot 314.
This, in turn, limits the motion of upper disc 238 relative to lower disc 244, including hot water inlet put 146a.
Teeth 290 of temperature limiting member 218 engage with corresponding teeth 316 on the upper housing 216. This engagement keeps the temperature limit WO 2808/D1371S PC'F/US2007/916278 device 218 from slipping under load and provides detents to indicate discrete adjustment positions. Flex arms 284 of temperature limiting member 218 provide a preload on the engaged teeth 290, 316 and to prevent temperature limiting member 218 from slipping due to vibration. This preload also gives the adjuster a tactile feedback to prevent over-correction of a temperature limiting member 218. The tab or indicator 292 of the temperature limiting member 218 also protrudes through the slot 320 of upper housing 216 and provides a visual indication to the user of the temperature setting. Marks may be provided on the upper housing 216 to provide reference points of the relative position of indicator 292 within slot 320.
With further reference now to Figs. 29, 30, and 35A-35C, valve assembly 210 is illustrated with the temperature limiting member 218 positioned in a low limit position "L". Indicator 292 in Fig. 29 shows the low limit position within slot 320 of upper housing 216. In Figs. 29, 30, and 35A, stem assembly 220 is in a fully-closed position. As detailed above, this means that the upper disc 238 engages the lower disc 244 so that water does not flow from either hot or cold inlet ports 146a and 146b to outlet port 148. As shown in Fig. 35B, valve assembly 220 is moved to an open hot limit position. Moreover, stem assembly 220 is pivoted about axis 324 to an open flow position and also pivoted about axis 326 to the temperature limit position as defined by the inclined surface 294 of temperature limiting device 218. In other words, stem assembly 220 is pivoted as far as possible to its hot, or left, position about axis 326 due to engagement of the extension 227 and inclined surface 294 of temperature limiting member 218. Fig. 35C illustrates the valve assembly 210 in an open cold limit position, where the valve assembly 220 is pivoted as far as possible to its cold, or right, position about axis 326 due to engagement between the extension 227 and base 258.
Figs. 36-38D show valve assembly 210 with temperature limiting member 218 in a high limit position "H". Indicator 292 in Fig. 36 shows the high limit position within slot 320 of upper housing 216. In other words, temperature limiting member 218 has been rotated counter-clockwise by approximately 90 degrees from the position shown in Figs. 29, 30, and 35A-35C. Such rotation is accomplished by pushing down on temperature limiting member 218 against the bias of arms 284, such that teeth 290 disengage from teeth 316 of upper housing 216. Temperature limiting member 218 is then free to be rotated by gliding surfaces 286 of arms 284 against slide surface 268 of coupling member 230, such that indicator 292 moves within arcuate slot 320.
Figs. 36-38A illustrate stem assembly 220 in a fully-closed position. Fig.

shows stem assembly 220 in a mixed temperature position where water flows from both hot and cold inlet ports 146a and 146b to outlet port 148 of upper disc 244. Fig.
38C illustrates stem assembly 220 in an open hot limit position where maximum flow is permitted through hot water port to outlet 148. As clearly illustrated by comparing Fig. 38C to Fig, 35B, the stem in Fig. 38C has rotated further about axis 326 toward the hot water position, or to the left. This is because the point of contact between extension 227 and inclined surface 294 is higher in Fig. 38C than in Fig. 35B.
As detailed above, in Figs. 36-38D temperature limiting member 218 has been rotated counter-clockwise approximately 90 from the position shown in Figs. 29, 30, and 35A-35C. Fig. 38D illustrates stem assembly 220 in an open cold limit position which is substantially the same as that position illustrated in Fig. 35C.
