Abstract

519,429. Relief valves. OLAER PATENT CO. Sept. 22, 1938, No. 27623. Convention date, Sept. 27, 1937. [Class 135] A by-pass relief valve for pumps, compressors and the like comprises a valve element 8 exposed on one side to the pressure of fluid delivered by the pump or the like and on the other side to the pressure of a resilient loading element such as the spring 9, and a separate auxiliary member 10 acted on by the pump delivery pressure on one face and by the pressure in the conduit 7 to which fluid is normally delivered on the other face which is of at least the same area as the first-mentioned face, the arrangement being such that after the valve 8 is opened by the pump pressure its lift is increased by the auxiliary member 10 which gives it a sudden blow and the valve remains open until the pressure in the conduit 7 has fallen to a predetermined value. As shown, the casing 1 has a connection 4 to the pump delivery, a discharge connection 5, and a connection 6 for attachment of the conduit 7 which may lead to an accumulator. The auxiliary member comprises a differential piston 10, the part 10a exposed to the pressure in the conduit 7 being materially greater than the area 8b of the valve exposed to the pump pressure. The member 10 has passages 11, 12 closed by a spring-loaded ball valve 13. According to the Specification as open to inspection under Sect. 91, the valve member and the auxiliary member may be in one piece. This subject-matter does not appear in the Specification as accepted.
