Three outlet mixing and diverter valve

Claim 1

In a fluid mixing and diverter valve, a hollow body closed at one end and having a tapered bore, hot and cold water inlets, a spout outlet, a spray outlet and a shower outlet; a tapered selector valve having a cylindrical bore rotatably nested in said tapered bore with longitudinally spaced sets of passages adapted for registry with said inlets, and on rotation selective progressive registry of one of said outletS and for determining the volume of flow therethrough, and including an intermediate non-registry shut off position; a cylindrical valve mounted within and constrained to axial movements with respect to said selector valve and having opposed displaced inlet passages to a mixing chamber therein, moveable in one direction relative to said selector valve for increasing the flow of hot water and decreasing the flow of cold water to said mixing chamber; and moveable in the opposite direction for decreasing the flow of hot water and increasing the flow of cold water; said selector valve passages determining flow from said mixing chamber to one of said outlets respectively; a centrally apertured inner lid mounted over the open end of the body and bearing against said selector valve; an axially adjustable and rotatable stem moveably projected and sealed through said lid, into said selector valve and cylindrical valve and affixed to said cylindrical valve for axially adjusting said cylindrical valve; a control ring secured to said stem having a tongue longitudinally and slideably keyed to said selector valve for rotating it selectively; a second lid co-axial to and spaced outwardly of and secured to said inner lid; an annular cover rotatively journaled at one end upon the body and at its outer end guideably retained by said second lid; a control lever moveably projected through said rotatable cover, at its inner end pivotally connected to said stem, and intermediate its ends fulcrumed between said lids; whereby rotation of said lever and its cover in a first plane simultaneously rotates said selector valve to one of a series of control positions, i.e., for fluid delivery to said spout outlet, spray outlet and shower outlet; and pivotal adjustment of said lever in a second right angular plane longitudinally adjusts said cylindrical valve to regulate water temperature.
