Abstract
1324761 Fluid pressure actuators WESTING- HOUSE BREMSEN UND APPARATEBAU GmbH 6 Jan 1971 [7 Jan 1970] 539/71 Heading F2F A spring applied, fluid pressure released brake actuator has two pistons 2, 14, coupled to a common output member 5, one piston 14 moving in a cylinder 11 partly housed within the other piston 2, fluid pressure acting through ports 16, 17 to hold the output member 5 in a position to disengage the brake, provision being made by means of a screw threaded union 4 between member 5 and a sleeve 13 of piston 2 to release the brake when the fluid pressure is lost. By unscrewing union 4, piston 14 is allowed to move into the release position under the action of a spring 24. Fluid pressure acting in a chamber 19 on piston 14 is in permanent communication through a bore 20, chamber 21 and filter 22 with atmosphere.
