Definitions
- the invention relates to a hydraulic control unit with a valve block at least two built-in valves and supply and discharge lines for the hydraulic fluid every valve.
- Hydraulic systems with several work rooms to be controlled are currently especially with several independent hydraulic actuators Movement of loads, such as in the hydraulic drives of the convertible tops convertibles, automatically operated trunk lids or other moving components on vehicles, mostly controlled by solenoid valves.
- the solenoid valves of the conventional system do not remain connected, which causes the components to move in an undesirable manner, endanger people and can damage the vehicle or the system. For this reason, must go through Additional components safety precautions are taken, which is the effort in constructionally and economically for the overall system further increased.
- In addition to the Applications in vehicle technology are of course also many other uses such hydraulic arrangements possible.
- valves have previously been installed in Cartridge construction mounted in a valve block. It has to be for every application A specially interconnected valve block can be developed and manufactured as the actuators must be controlled differently.
- EP-A-0 718 504 and DE-A-36 35 625 each have a construction with several valves in a housing, but with great design effort and high Space-dependent actuators are provided for each valve.
- Actuators are described a common actuator, both Paint in the form of a hand lever.
- the object of the invention was therefore a hydraulic control unit initially specified type, which with little structural and economical Effort allows a simple and flexible control of several valves while doing so At the same time, the weight and installation space of the unit can be reduced.
- a only common actuator for the valve elements of all existing Valves on the valve block is built, which with at least one actuator is equipped with the option of actuating one or more at a time of the existing valves to the or by means of a further actuating device each valve is movable.
- This arrangement allows for a single valve block a certain number of valves to find what the manufacture and Warehousing considerably simplified.
- the different requirements of The switching sequences of the hydraulic systems are controlled by the second one Actuator takes into account which the valves in the desired Sequence activated. This is also a reduction in size and in Weight connected, because for all valves a single actuator and only additionally a further actuating device for selecting the respective one actuating valve must be present.
- valve block This advantage is even more pronounced the more valves in the valve block. And also when assembling the Maintenance and any repairs are the simpler and clearer design an advantage, which also requires less effort from the electrical control needs and overall also significantly increases the economy of the control unit.
- the actuating device can of course also be used indirectly act intermediate elements on the actual valve element.
- an advantageous embodiment of the invention provides that the common Actuator is an electric linear stepper motor that is an exact controllable actuation of the valves guaranteed. If the valves are built accordingly even a proportional valve function can be realized with it.
- the common actuator is an electrically actuated magnet arrangement, can with this fast Actuator rapid opening and closing of the valves can be achieved.
- the further actuator for the actuator is an electrical Is stepper motor.
- a particularly compact arrangement can be achieved in one embodiment which is characterized in that all valves in the valve block are circular and are preferably provided with their axes aligned in parallel, the actuator movable in a circle and the electric stepper motor for the actuator as a rotary motor with concentric to the symmetry axis of the valve arrangement horizontal spindle is executed.
- the time between the selection of any two valves for actuation are kept very short, whereby the flexibility in the switching sequence can be used to the best possible extent can.
- a very simple and easily adjustable variant for the actuator of the Valves provides that the actuator by one or more fingers or one Disc with one or more tongue-like projections on the rotating spindle is formed.
- the actuator is formed by a perforated disc on the rotating spindle is a quick one It is possible to assume a position in which, if necessary, all valves at the same time can be switched, for example to an emergency operation of the otherwise to allow parts actuated automatically by the actuators. So the perforated disc For example, be carried out in such a way that in discrete, the actuators Valves corresponding to positions are present, except of course for those in the holes valves to be switched in each position. When the perforated disc is turned into a Intermediate position, all valves can then be switched together, which also can be done manually for emergency operation. This emergency operation could also be done by a second disc that can only be moved axially by hand without any holes, which is mounted over the first perforated disc, with programming of the Perforated disc can be omitted to an intermediate position.
- the further actuating device for the actuator with Control is bound, preferably with a freely programmable controller Je the switching sequence of the valves can be selected and changed as required, for example, several switching programs can also be created by the user Desired saved and kept available.
- valves are as in Valve block elaborated seat valves executed and protrudes at least part of the organs acting actual valve element out of the valve block.
- valves as in Valve block elaborated slide valves are executed, the slide from the Valve block protrudes.
- valves are used complete slide valve cartridges executed and in corresponding recordings of the Valve block are used, the in the fully inserted position Cartridges the slider protrudes from the valve block.
- the other according to the invention has realizing proportional valves Embodiment in which the moving parts of the valves on two different Stand out of the valve block and solely by the action of the actuator are displaceable, the advantage that it automatically optimal Security requirements are met.
- valve If namely the current for control If the valve suddenly fails, the valve remains in the just switched position and thus maintains its intended function until it is actuated is brought back into another switching position.
- Another advantage of this variant is significant compared to conventional control units - the more valves, the more more significant - lower power consumption, since after switching through the Actuator the valve remains in the set position and that Actuator then - until the next switching operation - be de-energized can.
- valve block Advantageously and with a particularly simple mechanical design or Producibility of the valve block is provided that the moving parts of the valves protrude on opposite sides of the valve block and alone through the action of two coupled to the same direction movement Opposite sides of the valve block arranged actuators are movable.
- valve block worked out lines additional components such as nozzles or Throttles in the tank lines and / or check valves in the pressure lines to be on. If, for example, the pump for the pressure fluid should fail, it will stop then blocking check valve maintains the pressure in the system and thus ensures that, for example, a convertible top cannot accidentally close or open.

- valve block 1 of the control unit is in the drawings shown as a cuboid, but could also have any other practical shape, in particular the shape of a cylinder or a polygon, the axes of the installed valves then preferably parallel to the axis of symmetry of the valve block 1 are oriented.
- the connections 2 for the are on the lateral lateral surfaces 1a Supply with pressurized fluid from the tank or the working pressure Hydraulic system pressure pump. At most, the tank or the pump could be flanged directly to the valve block 1, so that connecting lines and Seals can be saved and the risk of leakage can be reduced.
- the front and rear lateral surface 1b advantageously have bores for the insertion of check valves 3 in a passage extending parallel to the lateral surface 1b for the Pressurized fluid, from which passage feed ducts branching essentially at right angles to the actual valves 4, preferably 3/2-way valves or Valve arrangements with the same switching function.
- the passages of the connections 2 and to the output connections 7 also in the form of closed ones Ring channels around the axis of symmetry of the valve block, preferably with one each Pressure port and an outlet port, or in the form of along parts of the circumferential, curved or kinked passages.
- the valve slide 5 is actuated via an actuating element 10 in the form at least one finger on a rotatable shaft 11 above the top surface 1c of the Valve block 1 is adjustable but mounted in a rotationally fixed manner.
- an actuating element 10 in the form at least one finger on a rotatable shaft 11 above the top surface 1c of the Valve block 1 is adjustable but mounted in a rotationally fixed manner.
- disks with holes which fit the protruding ends of the valve slide 5.
- This function can be used instead of individual valves can also be implemented for groups of valves if a plurality of actuating members 10 available and / or for interaction with, for example, several valve spools 5 are designed.
- the magnets held in a frame 14 are energized only until the desired switching position of the valve 4 is reached, after which the Energy input in the power consumption overall significantly reducing turned off and the shaft 11 by suitable devices, such as elastic Elements such as axial coil springs, returned to the neutral basic position becomes.
- suitable devices such as elastic Elements such as axial coil springs, returned to the neutral basic position becomes.
- the valve slide 5, however, remain because no springs or the like on them act in the position reached and thus keep the valve in even without energy supply the switched position. This is an essential safety function in the event of a Malfunction in the electrical lines to the valve, which the unimpeded Function until the end of the working stroke of the respective controlled actuator guaranteed.
- a rotary stepping motor 15 is preferably used to rotate the shaft 11 about its axis mounted, the connection with the shaft to compensate for axial displacements 11 is rotatably coupled.
- the stepper motor 15 can advantageously with a Be connected to electronic control, which the switching sequence and position of the Valves 4 determined. This switching sequence and the respective position of the corresponding valve 4 determined in terms of circuitry or software and thus be given changeable.
- valve 4 connects the actuators via the connections 6 and the transverse channel 20, each with a second parallel to the passage and the front or rear lateral surface 1b extending passage 21 on each side of the valve block 1, through which passage 21 the pressure fluid pressed out of the actuators via the Output connections 7 is returned to the tank.
- transition grooves 22 elaborated, which the connection between the form individual channels and passages in valve block 1.
- Another embodiment of the control unit according to the invention with two Check valves, which together form a 3/2-way valve arrangement, is in the 4 and 4 shown in two parallel sections.

- the pressure fluid passes from the via short connecting channels 23 Check valve 3 to the first check valve 24 which controls the actuators Valve arrangement 24, 29.
- Its actual valve element, the ball 25, is both from the pressure fluid as well as from the spring 26 in the direction of the valve seat acted upon.
- a plunger 27 is provided in a transverse channel 28.
- the plunger 27 is pressed into the transverse channel 28 and so lifts the ball 25 from the valve seat or the plunger 27 again from the Spring 26 and / or the pressure of the pressure fluid on the valve slide 5 moves become.
- the same function is given for the second check valve 29.
- the two check valves 24 and 29 are to be alternately blocked or released the valve slide 5 in its axially central region with a constriction 30, i.e. a reduction in cross section, which extends over two to the ends of the Valve slide 5 conically widening sections 31 into the sections passes, which essentially completely the bore for the valve slide 5 to complete.
- the lower plunger 27 is the first Check valve 24 pressed completely into the transverse channel 28, thereby holding the ball 25 lifted off the valve seat and passes the connection from the connecting channel 23 the check valve 24 into a connecting passage recognizable in the section of FIG. 5 32 free, which leads to the outputs 6 to the actuators, the outer of the Outputs 6 leads an additional cross channel 33.
- the second switch position of the Valve spool 5 whose constriction 30 comes to rest on the first tappet 27, so that this is released and the pressure fluid and the spring 26, the ball 25 again can press on the valve seat.
