Abstract:
A dispensing valve unit adapted for coupling with a source of pressurized water and permitting the user to selectively deliver a mixture of soap and water or water only to a restricted dispensing outlet, or to prevent delivery of soap or water to said dispensing outlet, said unit comprising:a pair of at least partially interfitted inner and outer tubular assemblies forming therebetween a reservoir for liquid soap,the inner tubular assembly having an inner valve seat and adapted for connection between said source of pressurized water and said dispensing outlet and having a soap entry port through a wall thereof,the outer tubular assembly disposed at least partially about said inner tubular assembly and having a wall adapted to cover said soap entry port; anda shiftable valve body located within said inner tubular assembly and including an annular element and a valve stem received therein, said valve stem and annular element cooperatively defining a low volume control annular passageway therebetween, said element and valve stem being relatively shiftable,said inner and outer tubular assemblies being mounted for selective relative movement therebetween and permitting selective adjustment of the unit to a soap and water delivery position wherein said valve stem and element are relatively shifted to open said annular passageway in order to permit flow of water therethrough and said soap entry port communicates with said reservoir and permits passage of liquid soap through the soap entry port, to a full volume water-only delivery position wherein said valve body is spaced from said valve seat and said outer tubular assembly wall covers said soap entry port to prevent passage of liquid soap through the soap entry port, and to an all-off position wherein said valve body engages said valve seat, and said element and valve stem are shifted so as to close said annular passageway.
