摘要：A spray head assembly is made from a very few number of injection moldedparts. Preferably a pair of elongated housing shells fit together in face-to-faceconfrontation, with a spring biased actuator arm or control lever pivotally mountedbetween them. The lever has a metal shaft extending therefrom, which passes through aflexible cone in a rubber bulkhead to maintain a waterproof seal. In front of the bulkheadis a solid plastic plate having mounted therein a reciprocally slidable member controlledby the lever. In one embodiment, the sliding member contains a generally triangular ortapered opening or openings having a sector of a circle for a base. Depending upon theposition of the slide, the opening moves up or down to open or close a waterpassageway through the spray head. The sliding member first presents the smallersectors of the opening or openings to an associated sealing ring to minimize theabruptness of any change in discontinuity of water flow at the edge of the opening. Inanother embodiment, a stainless steel plate is countersunk in or affixed to the back ofthe sliding member to reduce wear. The spray head delivers water in a generallyrectangular spray pattern.
