Abstract
This mixing valve for a single spout, single handle faucet provides a stationary valve seat (24) having two fluid apertures, and a valve plate (28), relatively rotatable with respect to the valve seat and pressed against the valve seat surface. The valve plate has a generally central aperture (31) and a peripheral aperture (or bight) (30). The arcuate half-circle shape of the downstream outlets (27 and 27A) of the valve seat hot and cold fluid apertures in combination with the placement and shape of the apertures in the valve plate allows the mixing valve to be adaptable to use with either a knob (53) or lever-type (59) control handle and in back-to-back plumbing installations by simply rotating the valve plate 180.degree. relative to the valve seat upon installation.
Claims3
A mixing valve comprising a valve seat having a hot fluid aperture and a cold fluid aperture formed therein, the outlets of said apertures each being substantially arcuate in shape and forming almost a full half-circle enclosing a substantially circular land of the body of the valve seat with narrow neck portions of the body of the valve seat separating the converging ends of said arcuate outlets, a valve plate having a surface abutting said valve seat and movable longitudinally and transversely relative to said valve seat, said valve plate having a peripheral aperture and an aperture formed eccentrically relative to the center of said plate to establish selective fluid communication with portions of said arcuate hot and cold fluid apertures in said valve seat, and means for moving said valve plate relative to said valve seat in order to selectively register either said peripheral aperture or said eccentric central aperture with portions of said arcuate apertures.
