ABSTRACT:
A spray head assembly is made primarily 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. The sliding member contains a generally triangular or tapered opening 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 apex of the opening to an associated sealing ring to minimize the abruptness of any change in discontinuity of water flow at the edge of the opening. The spray head delivers water from a generally rectangular pattern of spray holes.
