Abstract
811,176. Fluid-actuatedvalves. DUNLOP RUBBER CO. Ltd. Sept. 25, 1956 [Nov. 12, 1955], No. 32399/55. Addition to 701,973. Class 135. [Also in Group XIX] A pressure liquid relay for pressure gauges as in the parent Specification in which a sealing ring 12a prevents pressure liquid leakage around the piston 12 from the downstream side 8 to the upstream side 2, and a spring 28 urges the piston away from the upstream side, thus preventing the abutment of the valve stem 22 with the cylinder end and the opening of the valve when downstream exceeds upstream pressure. The connection 2 leads to a source of pressure and the connection 8 to the pressure gauge.
