Abstract

1,016,276. Valves. DRESSER INDUSTRIES Inc. April 7, 1964, No. 14375/64. Heading F2V. [Also in Division F1] A pressure relief valve for a pump, including a body having a by-pass connecting an inlet 11 and an outlet 12, comprises a seat 22 in the by-pass 16, 19, a movable valve closure operatively associated with the seat and including a sleeve 23 and a wall 26 arranged transversely of and within the sleeve, and a fixed piston 31 arranged within the sleeve between the wall 26 and the seat 22 to provide a chamber 32, the piston having an opening 33 therethrough communicating with the chamber 32. The piston 31 is supported at one end of a stem 30, the other end of which is supported in the housing 17 by a threaded plug 41. The closure member 23, 26, is loaded to the closed position by a spring 52. The face 40 of piston 31 is constantly exposed to the pressure in the pump outlet which is transmitted through the opening 33 to the chamber 32 to develop a force to overcome that exerted by the spring 52 and open a passageway to the pump inlet.
