  • the sealing washers 10 and 11 are to avoid destructive overpressures pressure relief valves 12 and 13 brought in.
  • the pressure relief valve 13 is only in combination with hydraulic opening damping by a throttle valve 18 necessary, because otherwise none in this area of the piston chamber 1 critical pressures can occur.
  • a check valve 15 which is a manual opening enables the door even when the drive is switched off.
  • a check valve 14 leaves the hydraulic fluid with little loss when the door is opened automatically flow past throttle valves 17 into the piston chamber 1. How the valves 12 to 18 are arranged in detail, can be seen in Figure 1 become.

The same number and type of valves 13 and 16 is also in the Sealing disc 11 is present, only these valves are in the same direction installed so that an overpressure from the spring chamber into the piston 2 can escape.
  • the 2-2-way valve is designed with a relatively small control pressure on the control piston 22 a multiple times greater pressure in the piston chamber 1 of the swing door drive can be kept and the return flow the hydraulic fluid in the tank space 8 is prevented, so that the door, window or the like is kept permanently open can be, the motor 7 is only slightly loaded. If So the delivery pressure of the pump 6 is less than the pressure in the piston chamber 1, both areas are hydraulically separated from each other, so with the help the pump 6 now controls the 2-2-way valve by the control piston 22 can be.

  • the tank room 8 is z. B. by a hydraulic accumulator formed, even with a small change in volume of the hydraulic fluid. how they can arise from temperature changes, among other things.
  • an approximately constant low pressure on the suction side of the pump 6 causes so that a shaft sealing ring of the pump is permanently relieved.
  • This compensation memory can, for example, by a gas bubble Gas bubble accumulator with elastic membrane or bubble, a piston accumulator be formed with or without a spring or the like.
  • FIG. 2 shows a second embodiment of the invention Swing door drive shown.
  • This embodiment differs from that shown in Figure 1 in that here the inflow from the backflow is separated.

  • the pump 6 When the door is opened, the pump 6 generates a volume flow of hydraulic fluid, which is conveyed into the piston chamber 1. To do this, the Pump 6 due to the inertia of the door and the force of the spring 3 exert a correspondingly increased pressure on the piston 2. This increased Pressure closes and prevents the 2-2-way valve through the control piston 22 thereby draining the volume of liquid conveyed into the tank room 8.

  • the unit consisting of pump 6 and motor 7 is complete off. This also happens in the event of a power failure. As a result, the pressure drops due to leakage in the pump 6 or on the control piston 22 or on the additional valve 28 below a limit value, where the 2-2-way valve opens so that the hydraulic fluid flows through the throttle valves 17 can flow into the tank space 8.
