ABSTRACT:
There is disclosed a wand activated dispensing valve that can be installed on the spouts of water faucets. The valve includes a housing having an internal cup-shaped member with the bottom wall of the cup-shaped member being foraminous and having a substantial thickness. The bottom wall preferably has a plurality of circumferentially disposed radial slots in an outer annular area, surrounding a central wand aperture which receives a rod-like wand. Preferably the wand aperture is surrounded by an internal recess in the bottom wall of the cup-shaped member which receives the bulbous upper end of the wand, capturing the wand in the assembly. The lower end of the valve member rides on the bulbous upper end of the wand and the valve member is lifted when the wand is tilted to one side. The housing includes a valve plate having a central port which receives the valve member, the upper end of which seats against a valve seat carried by the valve plate. The housing has conventional threads at is upper end to permit attachment to the spout of substantially all water faucets.
