Abstract

270,381. Dewrance, Sir J. Feb. 3, 1926. Pressure-regulating valves.-A reducing- valve of the kind controlled by an auxiliary valve has both main and auxiliary valves provided with lift valve members balanced by a diaphragm and actuated by a second diaphragm. The main valve a is carried by a spindle c connected to a balancing diaphragm b and to an actuating diaphragm d backed by a piston d<1> open to atmosphere on its lower face. Inlet pressure is admitted through a manually actuated valve to the space above the diaphragm d and is ex hausted to the outlet through the auxiliary valve g, which is opened by springs when the reduced pressure acting on its actuating diaphragm falls below a predetermined minimum. Specifications 16313/05 and 20008/12 are referred to.
