ABSTRACT:
An improved faucet assembly having a cam actuated mixing control valve is disclosed. The assembly includes a housing having an interior bore defined by an inner wall portion having a pair of circumferentially spaced inlets and a pair of outlets. A control valve is slidably mounted in the bore so that the control valve can rotate and move in an axial direction therein. The valve includes a cylindrical portion having two circumferentially spaced passages formed therethrough and extending into an inner mixing chamber within the bore. The valve includes a pair of spaced elongated wall portions integrally formed with the control valve within the bore. An actuating assembly is operatively connected to the valve to move the valve in an axial direction and to rotate the valve in the bore. The actuating assembly includes an elongated control stem rotatably mounted within the mixing chamber and which has an eccentrically mounted actuating cam portion disposed between the elongated wall portion for engagement therewith. A pair of axially spaced retaining shoulders mounted on the control stem retain the valve at the ends of the elongated wall portions so that the valve moves with the stem in an axial direction. The outer surface of the eccentrically mounted cam portion engages the elongated wall portions to rotatably move the valve in the bore when the stem is rotated about its longitudinal axis.
