ABSTRACT:
A single-handle faucet for mixing liquid and water and controlling the flow rate therethrough. A valve element having a generally cylindrical shut-off seal and a generally cylindrical ported seal mounted axially adjacent each other on a stem portion of the valve element. A single handle is provided to shift the valve element axially of the bore to control flow volume and to effect shut-off, or rotationally to control water temperature. The relationships are such that both peripheral squeeze and water-pressure forces are employed to provide sealing actions at the shut-off seal and ported seal. The actuating means is a handle that extends through a slot in the valve body, and indicators are provided adjacent the handle to indicate temperature range.
