Abstract
570,487. Posts. SOC. D'ELECTRICITE MORS. Aug. 1, 1939, No. 22282. Convention date, Aug. 2, 1938. [Class 20 (i)] [Also in Groups XXVIII and XXIX] To control the movement of a fluid-operated piston 1, such as may be used for a telescopic mast for radio aerials, the piston 1 is connected to a dash-pot device including a perforated piston 6 which follows the movement of the piston 1. If excessive movement is given to the piston 1 the cylinder 7 of the dash-pot device actuates a check valve 10 to check in inflow of fluid to the cylinder 2, or it may act to open a relief valve. The orifice 8 of the dash-pot may be adjustable, and the valve 10 is operated only if the pressure produced by the cylinder 7 is sufficient to overcome the action of a spring 11 which normally keeps the valve 10 open. The device may be made to operate inversely if the piston 1 is being moved in the opposite direction under suction. The dash-pot device may be connected to the main piston by gearing, and may not act on the valves by relay means.
