Definitions
- the invention relates to a hand-operated control device, which in particular is used for hydraulic actuation of hydraulic valves and that has the features from the preamble of claim 1.
- Such a manually operated control device is e.g. known from DE 27 51 946 C2.
- the control unit has a control lever that over two shafts or stub shafts, whose axes span an axis plane and are at a pivot point cut, gimbal mounted on a device housing and thus from one Neutratposition is pivotable on all sides about the pivot point.
- a control signal generator are four directly controlled pressure reducing valves in the known device available, which are at an angular distance of 90 degrees perpendicular to the Axle plane standing and through the pivot point lever axis arranged are.
- Every pressure reducing valve has a tappet in the device housing is guided parallel to the lever axis, protrudes from the device housing and from a plate-like actuator firmly connected to the control lever against the force of a return spring and a control spring of the respective Pressure reducing valve can be depressed.
- Those attacking the pestle Return springs ensure that the control lever is always in a neutral position assumes if it is not operated from the outside and does not engage is provided for him in a pivoted state.
- the control lever is pivoted in one plane. those through the axes of two diametrically opposed Pressure reducing valves is determined, one of four pressure reducing valves, that is, a control signal transmitter is actuated.
- a control signal transmitter By swiveling the control lever on another level it is possible to close two pressure reducing valves at the same time actuate, the degree of actuation of a pressure reducing valve in comparison to measure the level of actuation of the other pressure reducing valve depends on the swivel plane.
- the invention has for its object a hand-operated control device with the Develop features from the preamble of claim 1 so that with him a variety of hydraulic without excessive increase in effort Valves can be operated safely.
- This task is performed on the features of a manually operated control unit the preamble of claim 1 according to the invention solved in that this Control unit with the features from the characterizing part of claim 1.
- this Control unit with the features from the characterizing part of claim 1.
- the control lever is together with the actuator around the lever axis from a first rotational position to a second Rotational position and vice versa rotatable, the first in the first rotational position Control signal generator can be acted upon by the actuator.
- a recess is in the actuator in the first rotational position of the control lever the further control signal generator, so that it is not in the first rotational position can be operated.
- By turning the control lever together with the actuator an area of the actuator reaches the second rotational position via the further control signal generator, so that its actuation is possible.
- the invention can preferably be applied to a manually operated control device, that around the lever axis at a respective angular distance of 90 Degree four has first control signal transmitter.
- the control of another directional valve axis in two directions is then possible according to claim 4 in that diametrically opposite each other with respect to the lever axis and in each case centered two further control signal generators are arranged between two first control signal generators are and that the actuator is provided with four recesses are in the second rotary position in the area of the first control signal transmitter.
- the actuator is provided with four recesses are in the second rotary position in the area of the first control signal transmitter.
- 90 A second pair is offset from the other two control signal transmitters to be arranged by further control signal generators.
- control lever is not rotationally symmetrical with respect to the lever axis trained so that based on its location can be recognized whether he takes the first or the second rotary position.
- the control unit shown is a hydraulic control unit, which is built on the basis of pressure reducing valves. Overall, are in one Device housing 10 eight pressure reducing valves 11 in a mutual Angular distance ⁇ of 45 degrees arranged around a lever axis 12.
- the Pressure reducing valves form the control signal transmitter of the control unit.
- Your inner Structure is generally known and e.g. DE 27 51 946 C2 can be removed.
- the plunger 13 one of which is a pressure reducing valve is assigned and in a mounting and cover flange 14 of the device housing 10 inserted guide bushes 15 in the direction of Lever axis are movably guided.
- the plunger 13 protrude with a rounded End beyond the cover flange 14 and the guide bushes 15. Through the Movement of a plunger 13 into the device housing becomes a control spring of a pressure reducing valve, or more generally a pressure reducing valve actuated.
- This actuation is initiated via the handle 20 of a control lever 21, the one carried by the device housing 10 and shown only schematically Cardan joint 22 is attached.
- This has two shafts, their axes stand perpendicular to each other and at a pivot point designated by 23 cut and span a plane called the axis plane may.
- the control lever 21 Due to the universal joint 22, the control lever 21 is on all sides around the Pivot point 23 is pivotable.
- the lever axis is perpendicular to the Axis plane and also goes through pivot point 23.
- the handle 20 is attached to a stem 24 of the control lever 21, which from the Lever axis 12 is bent out, so that the control lever 21 is not overall is arranged rotationally symmetrical to the lever axis 12.
- the stem 24 is over one internally threaded socket 25 with an upper part 26 of the universal joint 22 connected.
- a plate 30 is clamped, which extends in a plane running parallel to the axis plane, ie essentially is arranged perpendicular to the lever axis 12.
- the shape of this plate 30 is particularly evident from FIG. 3.
- the plate has the shape of a cross and is 12 with respect to the lever axis fourfold symmetrical.
- the individual arms 31 of the plate 30 are thus arranged at an angular distance of 90 degrees with respect to the lever axis 12.
- the plate was created from a circular plate into which four cutouts 32 have been introduced from the outer edge.
- a lower part 36 of the universal joint 22 is screwed into a locking bush 37, which is rotatably mounted in the device housing 10 about the axis 12 and e.g. is secured with a lock nut 38 on part 36.
- a locking bush 37 In the outer surface of the Locking bush 37 are located in a position perpendicular to the lever axis 12 Level two locking recesses 39, which are at an angular distance of 45 degrees from one another to have. They interact with a radially arranged locking pin 40, which a catch spring 41 tries to push into one of the recesses 39.
- the plate 30 is in the one in FIG Lines drawn position. You can see that the arms 31 over the Ram 13 of four first arranged at an angular distance of 90 degrees to each other Pressure reducing valves 11 extend. If the control lever 21 is now pivoted, so depending on the direction of rotation one or two of these first Pressure reducing valves actuated. The four further pressure reducing valves 11, the also have an angular distance of 90 degrees from each other and against the first pressure reducing valves are offset by 45 degrees, remain from pivoting of the control lever 21 unaffected, since they are in the area of the recesses 32 of the plate 30 are located.
- the path of the plunger 13 out of the device housing 10 is like that of the already used today and e.g. control devices known from DE 27 51 946 C2 limited by a stop, so that the plunger 13 despite the recesses 32 are held in the plate 30 on the device housing 10 and the plate 30 in its neutral position, in which it is located with all parts above the tappets 13, can be rotated without obstruction by the plunger.
