    1537430 Fluid-pressure control circuits BORSIG GmbH 8 Sept 1977 [3 Nov 1976] 37491/77 Heading F1P A double-acting actuator, 25, 35, 36, is operated by hydraulic liquid from a reservoir 23 which is pressurized by gas, and liquid is returned to an unpressurized tank 28 connected to the reservoir 23 through a check-valve 30. The actuator opens and closes a valve 1 in a gas line and the pressure of the gas in the line is used to pressurize the reservoir 23. The system is controlled by electromagnetically operated valves 12, 14. A hand pump 34 is provided for emergency use.

    communicated also with the control cavity of the valve 12 and between themselves via check valves 19 and 20.
    The battery 1 is connected to the distributor 6 by the hydraulic line 21, in which an adjustable dross / t, 22 and crane 23 are installed, and the tank 7 - by the hydraulic line 24. Parallel to the valve 22, the auxiliary pump 25 is connected to the hydraulic line 21 with manual control. Distributor 6 is in communication with hydraulic cylinders 2 and 3 by hydraulic stores 26 and 27, respectively.
    In the pneumatic line 13, the valve 28, the filter 29 and the molecular sieve 30 are installed in series, and the filter 31 in the pneumatic line 11. The main pipe 10 is connected to the pneumatic line 13 via check valves 32 and 33.
    Pneumohydraulic actuator works as follows.
    In the initial set, the closure body 5 is closed. When this valve 28 is open, and the valves 12, 17 and 18 are closed. To open the valve body 5, open the valve 17. Compressed gas from the main pipeline 10 through the pneumatic line 13 flows under pressure to the valve 14, sets the valve 6 to the left position, and through the check valve 19 to the pneumatically controlled valve 12, opening it. Compressed gas flows through the pneumatic line 11 to the accumulator I, creating in it an overpressure and displacing oil from it into the hydraulic line 21. The oil enters the hydraulic cylinder 2, moving its piston and driving the device 4, which opens the locking member 5. At the same time, the oil is displaced From the hydraulic cylinder 3 to the reservoir 7, by hydromagist, directs 24.
    After the valve is opened, battery 1 loses overpressure and oil from tank 7 flows through conduit 8 through check valve 9 back to battery 1. To close the valve, valve 18 is turned on and compressed gas flows through air line 16 to valve 14, switching the valve 6 in the right position. In this case, the oil from the accumulator 1 enters the hydraulic cylinder 3, the drive
    in action device 4, closing the valve body.
