There is disclosed a valve housing which has a mixing chamber (56) therein, first and second valve seats (58) in the bottom of the chamber that are laterally spaced from one another to provide inlet openings (43) connected to the chamber, and an outlet opening (68, 71) exiting from the chamber. A valve member (74) is positioned in the chamber, the valve member having a lower sealing surface (75) in slidable contact with the valve seats, porting means controlling the flow of water from the inlet openings to the outlet, and an aperture (82) which is open at the upper surface of the valve member. A bearing member (90) is mounted over the valve member, the bearing member having an axial bore. The upper stem section of an actuator (84) is rotatably and axially movably mounted in the bore, and a lower cam section of the actuator is slidably extended into the valve member aperture. Axial movement of the actuator stem section causes the actuator cam to abut against a wall of the valve member aperture, thereby causing the valve member to slide laterally over the valve seats and control fluid volume. Rotation of the stem section causes the valve member to rotate, thereby controlling the proportion of fluids entering from each inlet opening. |
