Abstract

1322808 Valves DAVIS PNEUMATIC SYSTEMS Ltd 29 Nov 1971 [30 Nov 1970] 56751/70 Heading F2V A valve member 5 is held by a spring 18 in a position in which an outlet 23 is connected to an inlet 13 until the back pressure at the outlet is sufficient to displace the valve members against the spring and connect the outlet 23 to an exhaust port 16. A pressure impulse is thus delivered at the outlet 23 and may be used to operate the piston of a pilot actuator. Removal of inlet pressure allows the valve member to return to its first position.
