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.
