ABSTRACT:
A spray head assembly is made from a very few number of injection molded parts. Preferably a pair of elongated housing shells fit together in face-to-face confrontation, with a spring biased actuator arm or control lever pivotally mounted between them. The lever has a metal shaft extending therefrom, which passes through a flexible cone in a rubber bulkhead to maintain a waterproof seal. In front of the bulkhead is a solid plastic plate having mounted therein a reciprocally slidable member controlled by the lever. In one embodiment, the sliding member contains a generally triangular or tapered opening or openings having a sector of a circle for a base. Depending upon the position of the slide, the opening moves up or down to open or close a water passageway through the spray head. The sliding member first presents the smaller sectors of the opening or openings to an associated sealing ring to minimize the abruptness of any change in discontinuity of water flow at the edge of the opening. In another embodiment, a stainless steel plate is countersunk in or affixed to the back of the sliding member to reduce wear. The spray head delivers water in a generally rectangular spray pattern.
