Filed: 1932-08-23
Abstract: 411,081. Fluid -- actuated valves. TRUBERT, R., 284, Rue de l'Arsenal, Arras, Pas de Calais, France. Aug. 23, 1932, No. 23592. Void [Abridged as open to inspection under Sect. 91 of the Acts, Oct. 13, 1932]. [Class 135.] A combined reducing and safety valve for maintaining a substantially constant pressure in a chamber 16 supplied by a pipe 17 from a source of higher pressure comprises a single pressure-responsive element 29 which may be a piston or a diaphragm adapted first to allow the reducing valve 23 to close and then in succession the safety valve 25 to open. The reducing valve 23 seats on a resilient washer 21 confined between an apertured partition 19 and a nut 22. The safety valve 25 similarly seats in an apertured cup washer 28 of leather or rubber mounted on the piston 29. When the fluid pressure on the piston 29 exceeds a certain desired value determined by the strength of a spring 30, the piston leaves the tail 24 of the valve 23 so that the latter cuts off the high pressure from the chamber 16 and the outlet 3. Any tendency of a higher pressure to accumulate in the chamber 16, due to the defective operation of the valve 23 or to other causes, is checked by the further descent of the piston 29. The latter movement causes the tail 26 of the valve 25 to abut against the valve casing so that the pressure is relieved by an outlet 32 leading to the atmosphere. The spring 30 may be adjustable or springs of different strength may be used.
