ABSTRACT:
A household appliance, solenoid controlled, pilot actuated inlet water valve has a diaphragm insert with a bleed valve that substantially closes when a main valve is open to reduce water and contaminate flow through the bleed passage. The pilot valve outlet extension has openings to reduce vacuum drawn from the outlet into an actuation chamber thereby further reducing water flow through the bleed passage. The bleed passage is internally and externally configured to reduce contamination impairment. An anti-hammer rib or lip is placed on the pilot valve outlet extension upstream of a guide tip which provides less close-fitting surface that may be impaired by contaminates while still dampening valve closing to reduce valve noise and pipe hammer.
