Abstract

1428996 Actuators SIEMENS AG 12 July 1973 [13 July 1972] 33406/73 Heading F1D [Also in Division H1] An hydraulic actuating device for a high voltage switch comprises a piston 3 linked to the moving contact 1 of the switch and having two surfaces 17, 17a on which pressurized fluid can act, the top surface 17a having a smaller area than the bottom surface 17, so that when valve 6 is moved to the left hand position pressurized fluid from tank 7 passes via channel 11, valve 6 and bores 23 and 16 to the larger area bottom surface of the piston to move it upwards, and when valve 6 is moved to the right hand position the piston descends, its top surface 17a being continuously subjected to the pressurized fluid in tank 7 and channel 11 being closed, fluid driven out from below the piston passing to tank 27 via bore 16 until projection 15 on the piston closes this bore when the fluid is obliged to pass out of the throttling bore 19 thus cushioning the last part of the opening movement and preventing rebound. The valve 6 has a portion 25 which closes bore 23 during descent of the piston, the valve being moved by a piston 10 due to pressure in a control line 10a.
