Abstract

112,548. Auld & Sons, D., Auld, J., and Graham, J. March 21, 1917. Pressure-regulating valves. -A pressure regulator actuated by a, spring-loaded diaphragm acting through a bellcrank lever has a lift valve member arranged in a guide provided with ports leading to an annular chamber surrounding the valve member. The diaphragm g is held against a collar h by a nut and is clamped circumferentially between the casing and a cup-shaped housing s for the loading spring r, by a nut k. The valve c which slides in a guide d provided with a groove d<2> and ports d' co-operates with a seat member a adapted to be connected to a high-pressure system by means of a coupling b and cone-faced joint a<1>. A. relief valce is fitted at m<4> or m<5>.
