Abstract

717,545. Relief valves. HIDER, C. W. May 20, 1952, No. 12688/52. Class 135 A valve for preventing the formation of a vacuum in a waste pipe leading from a sanitary appliance is situated at the end of a pipe Y branched from the waste pipe, the valve normally closing the free end of pipe Y solely under its own weight and comprising a single beat lift closure member C combined with a piston valve element B so that the two are in series, and when a vacuum tends to form in the waste pipe, the pressure of the external atmosphere, acting on the member C, raises the valve device and allows air to enter around the closure C and through coinciding slots A, E in the piston closure and its surrounding casing respectively. The closure C is faced with rubber.
