Abstract

199,541. Farrow, A. E., and Plowright, T. H. April 19, 1922. Fluid-actuated valves; locking-catches.-A safety vaive particularly applicable for use on the compressed air bottles used for starting Diesel engines is fitted with automatic locking means so that when the valve is opened to relieve pressure it is retained open until reset manually. The casing contains a spring- pressed spindle 3 which has a recessed portion 6 and a reduced portion 7 terminating in a valve 8. When the pressure from the container rises unduly the piston 3 is lifted to open the inlet port and immediately afterwards to uncover the release ports 10, and at the same time the spring detents 12 are shot into the recess 6 to lock the piston until released by hand.
