Abstract

PURPOSE: To permit ready installation of a O-ring on the outer periphery of a discharge pressure valve seat by constructing an O-ring groove with an annular stepped portion formed on the discharge valve seat outer periphery and an O-ring retainer fitted on the discharge valve seat outer periphery.
CONSTITUTION: A pressure discharge valve seat 9 having a pressure outlet 14 and a pressure bearing plate 12 are held in contact with each other with O-ring 8 and 10 interposed between them. The inner periphery of a cylindrical portion 12a dependging from the pressure bearing plate 12 and the outer periphery of the pressure discharge valve seat 9 are held in contact with each other with the O-ring 8 interposed between them. Thus, the pressure bearing plate 12 is brought to an open position against the tensile force of and spring 4 at the time of the pressure discharge, and after the pressure discharge it is automatically returned by the tensile force of the spring 4. An O-ring groove 8 for receiving the O-ring 8 on the outer periphery of the pressure discharge valve 9 is constituted by an annular stepped portion 16 provided on the outer periphery of the pressure discharge valve seat 9 and an O-ring retainer 7 fitted on the outer periphery of the pressure dischage valve seat 9.
