Abstract

1516692 Fluid actuator KNORR-BREMSE GmbH 13 June 1975 [25 June 1974] 25455/75 Heading F1D To prevent the ingress of dirt or moisture, a spring chamber 13 of a spring/pressure fluid actuator is connected to atmosphere via an annular pre-chamber 37 surrounding the spring housing and an inlet tube 19. As shown the tension operating rod 31 is actuated by the springs 35 and released by air-pressure in the chamber 3 and the pre-chamber is secured to the housing by straps 41.
