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 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.
