Abstract

1421034 Fluid pressure actuators RESEARCH ENG CO 2 Feb 1973 5349/73 Heading F1D The piston 125, Fig. 2, of a fluid pressure actuator, for rotating a valve stem 150, is returned by a spring-loaded washer which permits fluidflow between opposite sides thereof. and is guided within a cylinder 130 by tie-rods 141, 142. The two springs shown in Fig.2 may be replaced by a single spring 171, Fig.4.
