Abstract
A mixing valve has a base plate adapted to be fixedly mounted on a base fitting and a housing sleeve centered on an axis, mounted on the base plate for rotation about the axis, and formed with a radially open window. A stationary valve plate is fixed on the base plate inside the sleeve and formed with at least two incoming liquid ports and one outgoing water port spaced therefrom. A movable valve plate flatly sitting on the stationary plate inside the sleeve is formed with a chamber alignable with the ports therein. This movable plate is angularly and radially displaceable relative to the axis so the chamber variously overlaps and interconnects the ports. A control member fixed inside the sleeve to the movable valve plate is pivoted on the inner end of a control member also pivoted on the sleeve and having an outer end projecting radially from the sleeve through the window. The sleeve has a lower end rotatably mounted on the base plate and an internally threaded upper end. A holddown ring is threaded in the upper sleeve end and bears axially downward on the member and valve plates.
