MIXING VALVE WITH GRADUATED TEMPERATURE MODULATION

摘要

A valve assembly for mixing hot and cold water includes a generally cylindrical sleeve having hot and cold inlets and outlets and a notable non-reciprocal valve member positioned therein to control the mixture of hot and cold water in the outlet stream. T he valve member has a hollow stem tube having hot and cold inlet and outlet ports which are notabl y 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 rib s, rims and raised edges provide a smoother fluid passageway for increased flow and for the eliminating of stacking.
