Abstract
A pressure control valve, which has a main valve for control, capable of opening and closing a valve hole by means of a diaphragm, and controls the pressure of a fluid by the agency of the main valve for control, comprises a non-return auxiliary valve located around the main valve for control so as to be coaxial therewith. The non-return auxiliary valve includes a cylindrical portion to be guided by a valve guard body having the valve hole therein and an annular rib extending outward from one end of the cylindrical portion. The rib can engage an auxiliary-valve seat on an outlet-side case.
