- the Control valves are therefore modular, depending on the application interchangeable.
- a spherical sliding block 22 sliding on, which together with one in FIG. 1 shown spherical recess 23 of the swash plate 12 the ball joint sliding connection 17 forms.
- the sliding block 22 could also be reversed slide against the swash plate 12 and the spherical Recess 23 may be formed in the actuating piston 18.
- FIG. 2 The first embodiment of the invention Power control device 2 is enlarged in FIG. 2 shown.
- Fig. 1 are the same Identify elements with matching reference numerals in order to facilitate the assignment.
- the adjusting piston 18 is cup-shaped and has a central fastening wick 30, which a Has thread.
- a threaded section 31 an extension 32 screwed, which is in axial direction through the control piston 18, the control piston 20, a second spring mount 33 and return springs 50, 53 extends.
- a valve sleeve 35 connects to the actuating piston 18, which a first operating pressure port 36, which with the Operating pressure of the piston engine 1 is connected, and a Has tank connection 37.
- the control piston 20 is in radial direction surrounded by the valve sleeve 35 and will penetrated by the extension 32 by a Recess 41 of the control piston 20 is passed through.
- the control piston 20 has a first groove 38, which with the first operating pressure port 36 is connected and on which is a first contact surface 39 for the operating pressure the piston engine 1 is formed. About the first The operating pressure of the piston engine 1 is exerted on the contact surface 39 an axial force on the control piston 20.
- a second Groove 40 in the control piston 20 is connected to the tank connection 37 connected.
- the actuating piston 18 has an actuating pressure chamber 42, which is designed as a recess in the actuating piston 18.
- the Signal pressure chamber 42 stands over axial bores 59a and at least one radial bore 59b in the valve sleeve 35 a first control edge 43 and a second control edge 44 of the control piston 20 in connection.
- a first control edge 43 and a second control edge 44 of the control piston 20 in connection.
- radial bore 59b over the first Control edge 43 with the first groove 38 or via the second Control edge 44 connected to the second groove 40.
- Position of the control piston 20 is therefore the pressure in the Signal pressure chamber either increased or decreased.
- the Signal pressure chamber 42 is in the valve sleeve 35 Integrated discharge throttle 45 with the tank connection 37 connected so that the actuating piston 18 when pivoting to the maximum displacement volume, the hydraulic fluid from the Signal pressure chamber displaced.
- the control piston 20 strikes with a first end 46 a central recess 47 of the valve sleeve 35 and is at a second end 48 with the second spring holder 33 connected, which has an outside step 49.
- a first return spring 50 is supported, which in is penetrated in the axial direction by the extension 32.
- the first return spring 50 is supported on one end outer support sleeve 52a, which with an inner Support sleeve 52b forms a first spring holder 51.
- At the inner support sleeve 52b supports a second Return spring 53 from.
- the first spring holder 51 is in contact a lock nut 54 on which on a thread 55 on End of the extension bolt 32 is screwed on.
- the lock nut 54 is an adjustment of the Spring tension of the return springs 50 and 53 through Screw the spring holder 51 in relation to the extension 32 allows.
- the return springs 50 and 53 and the first Spring receptacles 51 are in a spring receiving space 34 arranged and are surrounded by a spring sleeve 56.
- This is designed to be removable and with a sealing element 57, e.g. B. an O-ring sealed.
- Another sealing element 58 which can also be designed as an O-ring, seals the power control device 2 against the Piston engine 1 from.
- the mode of operation of the power control device 2 is based on the background that the output of the Piston machine 1 from the swivel angle ⁇ of the swash plate 12 and is dependent on the working pressure. Is the swash plate 12 relative to axis 3 at a right angle ( ⁇ 0 °), the piston machine 1 is idling. Once the The angle ⁇ becomes larger, the piston machine 1 begins To promote hydraulic fluid. To regulate the delivery rate or limit, the control valve 19, the control piston 18 so that the swash plate 12 under a Angle ⁇ , from 0 ° to a certain maximum angle is enough, is tilted. The maximum angle is determined by the Basic position of the actuating piston 18 defined. The Piston machine 1 always starts at this maximum angle, to build up enough pressure.
- control piston 20 leads to a larger opposite movement of the actuating piston 18, which presses against the swash plate 12 and thereby the swivel angle ⁇ is reduced.
- the pressure in the signal pressure chamber 42 is thereby Control valve 19 on a between tank pressure and Operating pressure lying signal pressure regulated. As long as the Signal pressure chamber 42 in connection with the first groove 38 stands, hydraulic fluid is under operating pressure in the Signal pressure chamber 42 pressed, whereby the actuating piston 18 the Swash plate 12 in the direction of a smaller swivel angle ⁇ emotional.
- the power control device 2 leads to a approximately constant maximum power of the piston engine 1.
- the assumed values of pressure and delivery volume are in a pressure-delivery volume diagram (p-V diagram) a straight line, the slope of which in this area is approximately the Rise of the theoretical power hyperbole in the p-V diagram corresponds.
- FIG 3 is a second embodiment of the power control device 2 according to the invention shown, which differs from the first embodiment by a differs second operating pressure port 60, which with the operating pressure of another, not shown Piston machine is connected.
- the otherwise identical execution of the Power control device 2 is therefore not in the following described again.
- the exemplary embodiment is in FIG. 3 provided with identical reference symbols in order to assign them to facilitate.
- Control piston 20 has a third groove 61, which with the second operating pressure port 60 is connected and on which has a second contact surface 62 for the operating pressure the other piston machine is formed. About the second Operating surface 62 exerts the operating pressure of the others Piston machine another axial force on the Control piston 20 out.
- a corresponding choice of the individual Operating pressures or the individual delivery volumes of the Piston machine 1 and the other, not shown Piston machine leads to the fact that the invention Power control device 2 also as a total power controller can be carried out, the sum of the services of Piston machine 1 and the other, not shown Piston engine is limited to a predetermined maximum.
- the invention is not shown on the Embodiments limited, but can also with a Power control device 2 in a different design or Axial piston machines 1 in a different design are used come. It should be emphasized that the travel of the control piston 18th is independent of the travel of the control piston 20 and despite a very slight adjustment of the Control piston 20 a much larger travel range Control piston 18 can be reached.
