Abstract

563,672. Relief valves. ERNST, W. March 31, 1943, No. 5180. [Class 135] A relief valve having a spring-loaded piston valve member 27 adapted to control an outlet port 34 is provided with a main area 46 subject to inlet pressure and with an opposed smaller area 37. The outlet conduit is fitted with a throttle 14 and is connected by a branch pipe 35 with the chamber 36 above the smaller area. When the valve is lifted by excess pressure to open the port 34, pressure is admitted to the chamber 36 to stabilize the valve. A passage 28 through the valve continuously admits inlet pressure to the spring chamber to act on an auxiliary area to balance in part the pressure acting on the area 46.
