Abstract
An electromagnetically actuated appliance water inlet valve having an elastomeric valve seat with molded in reinforcement stiffener to minimize distortion at assembly and upon exposure to high water line pressures. Lugs on the electromagnetic armature guide engage the periphery of the reinforcement to create a subassembly of armature, return spring, valve seat and guide for ease and economies of assembly. One embodiment of the reinforcement comprises an apertured disc. Other embodiments comprise an annular ring having 'C' shaped and 'U' shaped transverse sections. Tabs provided in the base of the ferromagnetic pole frame are deformed over a recess in the valve body to provide positive retention of the pole frame to the body.
