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. The valve member has a hollow stem tube having hot and cold inlet and outlet ports which are notably 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.
