Abstract

1481969 Valves WABCO WESTINGHOUSE GmbH 6 Nov 1974 [6 Nov 1973] 48099/74 Heading F2V A valve for a multi-circuit protection arrangement has a valve member 15 which is adjustably biased on to its seat 16 by a spring 27 and is provided with two concentric annular sealing lips 38, 39, the outer of which is shorter and the inner of which has breaks therein. On rise of pressure in the inlet 13 the lip 39 first lifts off the seat to allow a restricted flow through the gaps in the lip 38 to the outlet 11. Further pressure rise lifts the lip 38 off the seat and the pressure in the outlet acts on a diaphragm 25 to counteract the spring bias to hold the valve member off the seat. Two such valves are shown each having an inlet connected to a compressor and an outlet connected to a separate braking circuit including a reservoir. The arrangement is such that if either circuit becomes defective the other can be charged, the valve member of the defective circuit only lifting the lip 39 from the seat.
