Abstract

672,696. Fluid-actuated valves. UNITED AIRCRAFT PRODUCTS, Inc. March 16, 1949, No. 7237/49. Class 135. A valve actuated by fluid pressure under the control of an electromagneticallyoperated auxiliary valve member has inlet and outlet ports 16, 19, respectively, Fig. 2, a main movable valve member 27 coacting with a seat 28 and integral with a piston 24 and a fluted guide 25, and an auxiliary valve member 35 coacting with a seat at the end of a passage 34 through the piston and valve member and urged, against a spring 36, towards closed position by an armature 37 upon energisation of a solenoid 42. The piston 24 permits leakage from the inlet ports to a chamber 32 whence fluid may escape through the passage 34 except when the auxiliary valve member is closed, when pressure developed in the chamber 32 opens the valve member 27 against a loading spring 29. In a modification, the auxiliary valve member seats on a fixed orificed plate at the end of the cylinder accommodating the piston and is spring-urged to the closed position, so that the main valve member is opened when the solenoid is de-energised. Also, instead of providing a leaky piston, an external conduit supplies fluid to the chamber behind the piston. Fig. 4 illustrates a further modification, also having a spring-closed auxiliary valve member 94 seating on a fixed plate 87, but in which the housing is formed to facilitate connection into a pipe line whereas the other constructions are intended for insertion into a pump casing. In Fig. 4, fluid from the inlet 79 passes through an orifice 91 into a chamber 92 connectable through a passage 103, with the outlet 81 under the control of the auxiliary valve member. Specification 493,169 is referred to.
