Abstract
The pilot operated valve assembly includes a flexible diaphragm (A) which selectively engages a valve seat (B) to open and close a fluid passage through the valve. The diaphragm has a plurality of filtering apertures 20 and an inward peripheral attaching projection 80. A diaphragm insert (C) is frictionally received in the diaphragm. The diaphragm insert has a pilot supply aperture 74 in fluid communication with a peripheral recess 76 extending inward from a peripheral edge. The diaphragm filtering apertures 20 are disposed in fluid communication with the peripheral recess 76 and the pilot supply aperture 74. The insert peripheral edge has a peripheral valley 82 for receiving the peripheral projection 80 of the diaphragm. The insert has a pilot outlet aperture 66 which is selectively opened and closed by an armature assembly (D). A guide shell (E) aligns the armature assembly (D) with the pilot outlet aperture 66 and defines a pilot reservoir with the diaphragm (A).
