Abstract

1,046,074. Valves. CONCENTRIC (ENGINEERING) Ltd. Feb. 4, 1965 [Feb. 12, 1964], No. 5794/64. Heading F2V. A valve for controlling the flow of hydraulic fluid has a spring-loaded contra-piston housed in a spool so that when the pressure of the fluid reaches a predetermined value the contrapiston is displaced against a reaction member to return the spool to a position in which the flow is cut off. The valve is the same as that described in Specification 1,046,075.
