ABSTRACT:
A solenoid valve includes a diaphragm assembly which isolates the fluid being controlled by the valve from the solenoid cell and the armature. The diaphragm assembly includes integrally formed poppet members and sealing rings which prevent misalignment of component parts. Force is applied by the armature on the diaphragm via a force ball which provides a central force and eliminates misalignment. In an alternative embodiment the force ball is eliminated and the diaphragm assembly is connected directly to the armature.
