Definitions

  • the invention is based on the object Generic control device according to the Form the generic term so that it is dependent is automatically controlled by the direction of rotation.
  • a control for the invention alternating switching of two valves provided that simple, practical and insensitive to faults is, at the same time a minimum of space necessary is.
  • the first and second controlled valve of the valve device each as 3/2 valve and both valves to form the Overall valve device as a 4/2 valve educated.
  • the axial displacement movement of the Control axis on a acting as a valve spool Valve sealing element that is transferred from the pump incoming line in one switch position only with the one, e.g. leading to the one cylinder space Line and in the other switch position only with the others, e.g. leading to the other cylinder space Line connects, but not to the Pump connected line connected to the tank is.
  • the valve sealing element only moves with very little force of a spring on the Control area (mouths of the three lines) pressed.
  • This pressure force is further increased by a hydraulic force acting in the same direction amplified, which is caused by the two hydraulically effective surfaces, namely the front Pressure area of the valve sealing element is smaller than that rear, hydraulically effective cross-sectional area is, this front and back through the in the recess provided bore are connected.
  • a linear guide arranged in the hollow body in turn on the back of a housing-fixed, supports plane abutments.
  • FIG 1 is a schematic cross section Hydraulic piston-cylinder unit 10 side with an eye hole 11 for mechanical connection shown, in addition to a combined drive and Control unit 12 is provided.
  • This has one reversible, designated 13 in total Electric motor, the motor shaft 14 as Actuating shaft 15 ( Figures 2 and 4) one Actuator with one in the axial direction Control rod movable between 2 switch positions 16 is formed.
  • the actuating shaft 15 and the Control rod 16 are in a thread-like Active connection, the first embodiment in the Figures 2 and 3 and their alternative embodiment this is shown in Figure 4.
  • FIG. 4 there is one axial blind bore 17 in the control rod 16 with an internal thread 18 is provided, one to this adapted external thread 19 of the actuating shaft 15 is provided. After that in the blind bore 17th external thread screwed in via the internal thread 18 19 only a certain stroke (few threads) can perform during the first rotary motion the actuating shaft 15, first the control rod 16 shifted in the axial direction. If the Actuating shaft 15 reached the end of the thread or has come into contact at the end of the blind hole, she takes the control rod 16 in one or the other direction of rotation with.
  • the control lever 39 is as a tilt bearing 41st movable, two-armed lever formed, the an actuating arm 42 a control connection of a formed as the first valve 44 valve device acts while the other operating arm 43 the another control connection of a second valve 45 the Valve device releases and vice versa.
  • Both that first valve 44 of the valve device as well second valve 45 are 3/2 and both are together be designed as a 4/2 valve. In any case it is a seat-sealed directional valve.
  • the valve 44 is an example below described, which has the same structure as that valve 45.
  • the first valve 44 with two on one seat overlying balls 441 and 442 provided, which over a control rod 443 alternately from the seat can be lifted off, the control rod 443 with radial play in a bore 444 and where this is connected to the first connection 445, the over the one of the two balls either with the Pump pressure leading line 46 or over the other of the two balls with the line leading to the tank 446 is connectable.
  • the same design applies to the second valve 45. The same parts are therefore obtained the last of the three-digit reference number Digit.
