Abstract: The rigid, plastic insert molded into the diaphragm has a raised seat against which the soft tip, solenoid plunger seats with no need for critical registry, thus allowing greater clearance between the plunger and guide. The insert includes a depending boss which cooperates with the outlet to throttle flow during closure to reduce water hammer. The necessary bleed hole is in the insert for greater precision and uniformity of operation. The diaphragm material is molded to include a spacer preventing seating the bleed hole against the cup-like portion of the guide with consequent inability to close.

Abstract: The dishwasher drain valve provides straight through flow with the valve seat at about 45* to the flow to provide increased velocity tending to straighten the flow of elongated objects (toothpicks, etc.) and decrease chances of such debris becoming lodged in the valve housing. A bellows seals the stem and solenoid from contact with liquids and entrained contaminants. The end of the bellows functions as the valve. Collapse of the bellows onto the stem is prevented by stiffening rings. The stem is guided for linear movement and tolerates some degree of misalignment with the solenoid.
