Definitions
- Liquid regulator for supplying a consumer with liquid from a liquid supply
- the invention relates to a liquid regulator for supplying a consumer with liquid according to the preamble of claim 1.
- the liquid consumers can be, for example, tips of writing, painting and brushing devices or application and spraying elements of liquid dispensers.
- the ink is supplied to the writing tips through capillaries, which suck ink from a storage container by means of their capillary force, an air compensation opening in the storage container being dimensioned such that the ink removed is replaced by air only when the pressure drops below a negative pressure.
- the negative pressure in the container is sufficient to prevent the ink from spilling despite its weight.
- a device according to the preamble of the attached main claim is known, the valve of which is arranged between a liquid storage container and an intermediate reservoir, from which the consumer is supplied with liquid via a capillary line. If the intermediate reservoir increasingly empties when the liquid is used up, a negative pressure is created there, so that the valve bordering on one side with the liquid storage container and with the other side with the intermediate reservoir opens and the intermediate reservoir is filled again with liquid.
- a peculiarity of this system is that it becomes a permanent The supply of liquid can break if the negative pressure balances out otherwise.
- the invention has for its object to provide a generic device that ensures a reliable supply of liquid to a consumer with a simple structure.
- the capillary controller according to the invention which can be extremely simple in its construction, works extremely functionally reliably because of the high forces occurring in capillary systems and ensures a high level of leakage security for the consumers it supplies.
- claims 2 and 3 ensure that the liquid supply line or the consumer downstream of the capillary space reliably soaks up liquid continuously.
- Claims 4 to 7 are directed to advantageous features of the capillary valve, with the features of claim 6 being particularly reliable.
- the pressure acting from the liquid supply column can be used directly as the valve opening force.
- the leakproofness is further increased, since ventilation of the interior of the elastic bag is not necessary.
- FIG. 1 shows a cross section through a fiber pen equipped with the liquid regulator according to the invention
- FIG. 2 is an enlarged view of the capillary regulator contained in FIG. 1,
- Fig. 3 is a plan view of the valve member of the capillary controller shown in FIG. 2 and
- Fig. 4 is a schematic sectional view of a printing device provided with the device according to the invention.
- FIG. 5 shows a detailed view of an embodiment modified from FIG. 1.
- a fiber pen has a housing 2 which is divided into different chambers in its interior by partitions 4, 6 and 8.
- the partition 4 is provided with an annular flange 10, on which a flexible sack 12 is fitted, which contains a liquid supply 14, the liquid being any known writing liquid, for example ink.
- An opening 16 leads through the partition 4 into a line 18, from which a valve opening 20 leads through the partition 6.
- the line 18 can be filled with a flow-damping material so that pressure waves from the liquid supply 14 have no effect on the valve functions.
- a line 24 is formed in the partition 6, the diameter of which is advantageously smaller than the distance d and which opens into the space between the partition 6 and the valve member 22 via a connecting opening 26.
- the line 24 leads to a capillary writing tip 28 which is customary in its construction, as is used for fiber-tip pens.
- the writing tip 28 is inserted into a flange of the partition 8 and is additionally held in its front region by the housing 2, which tapers there conically.
- the writing tip 28 can also protrude directly into the space between the valve member 22 and the partition 6.
- Air compensation openings 30, 32 and 34 provide ventilation of the interior of the housing 2.
- an elastic connection can be provided instead of an articulated connection.
- valve member 22 closing valve opening 20 the following force acts on valve member 22 through valve opening 20 from the liquid column present on the left side of valve opening 20:
- valve member 22 on its side facing the capillary space 36 and the partition 6 on its side facing the capillary space 36 consist of a material which is wetted by the liquid, the liquid is sucked into the capillary space 36 as a result of the capillary action if necessary, additionally pressed into the capillary space 36 by the hydrostatic pressure of the liquid acid. This causes the valve member 22 to be closed by the liquid in the capillary space with the following force in the closing direction, i.e. is pulled against the edge of the valve opening 20:
- o surface tension of the liquid
- d thickness of the capillary space 36
- f surface of the valve member 22 wetted by liquid.
- the opening force exerted by the height of the liquid column is only a fraction of the closing force, as a result of which the valve is closed extremely securely and there is no risk of opening in the event of impact movements, provided the mass of the valve member 22 is small.
- the valve member 22 closes the valve opening 20, since the capillary space 36 is sufficiently filled with liquid.
- the capillary space 36 becomes increasingly empty.
- the closing force of the valve member 22 decreases, so that when the capillary space is sufficiently empty, the liquid pressure and / or a shaking movement opens the valve member 22, whereupon the capillary space is filled with liquid again by the hydrostatic pressure or the capillarity and the valve member 22 opens 20 again closed.
- the process starts again. It is advantageous if the line 24 has a greater capillarity than the capillary space 36, since this ensures that the line 24 "vacuums" the capillary space.
- the device described can be modified in many ways.
- the internal division of the housing can be different; the writing tip can be different; the arrangement of the ventilation openings can be modified; in the area of the bag 12 the housing can be evident, so that the bag can be replaced in a simple manner. Even if the entire device is completely blank, it reliably fills itself completely with ink after inserting a new sack, without the risk of contamination.
- the valve member 22 is designed here as an elastic membrane 50, which is reinforced by means of a reinforcing plate 52.
- the elastic membrane 50 is rigidly connected to the partition 6, so that between the region 54, which is rigidly connected by adhesive, for example, and the region reinforced by means of the reinforcing plate 52, an area remains free which forms a joint of the valve member 22.
- the capillary space 36 is defined in that the partition 6 is recessed to a corresponding depth, the end edge of the valve opening 20 facing the valve member 22 projecting by the thickness or depth of the capillary space.
- FIG. 4 shows the construction according to FIG. 1 and FIG. 2 schematically in its application in a printing unit 56 of a printing device 58, as is used, for example, in ink jet printers.
- the liquid supply 14 here borders directly on the partition 6 with the valve opening 20.
- the writing tip 28 (FIG. 1) corresponds to a capillary wick 60 which supplies the printing unit 56 with liquid.
- FIG. 5 shows an embodiment of the controller according to the invention modified from FIG. 1: the valve member 22 is designed here as a plate 70 which is articulated on the partition 6 and has an opening in which a ball 72 is fastened.
- the ball 72 can also be made in one piece with the plate 70, for example by injection molding. be educated.
- the ball 72 which should be made of the lightest possible material, the closing safety of the valve 20, 22 is improved and its sensitivity to contamination is reduced.
- the consumer which is also designed here as a capillary writing tip 28, directly adjoins the capillary space 36, which simplifies the construction and increases functional reliability, in particular since the capillarity of the writing tip 28 is greater than that of the capillary space 22. Otherwise, the function is the same as that of the embodiment according to FIG. 1.
