Showerhead

A valve assembly for mixing hot and cold water includes a generally cylindrical sleeve having hot and cold inlets and outlets and a rotatable non-reciprocal valve member positioned therein to control the mixture of hot and cold water in the outlet stream. The valve member has a hollow stem tube having hot and cold inlet and outlet ports which are rotatably engageable with the hot and cold inlets and outlets of the sleeve. The sleeve hot water outlet is generally larger than the sleeve cold water outlet. The sleeve and stem tube inlets and outlets are not limited to a particular shape and/or geometry. The fluid engagement between the sleeve hot and cold water outlets and the stem tube hot and cold water outlets provides a large mixed water temperature range.

A valve assembly for mixing hot and cold water includes a generally cylindrical sleeve having hot and cold inlets and outlets and a rotable non-reciprocal valve member positioned therein to control the mixture of hot and cold water in the outlet stream. The valve member has a hollow stem tube having hot and cold inlet and outlet ports which are rotably engageable with the hot and cold inlets and outlets of the sleeve. The stem tube hot water inlet port has at least one tapered portion with is engageable with a tapered portion of the sleeve to provide a larger range of mixed range temperatures in the resulting outlet stream. Sleeve ribs, rims and raised edges provide a smoother fluid passageway for increased flow and for the eliminating of stacking.

The combination of a shower valve having a metallic movable stem to control operation of the valve and a non-metallic high strength composite handle adapter secured to the stem for movement therewith, with the non-metallic handle adapter preventing galvanic corrosion between the metallic valve stem and a metallic handle attached to the handle adapter.
