ABSTRACT:
A self-contained, unitary mixing cartridge for use in hot and cold water faucets for manually selecting the mixture-proportions and flow-rates of water supplied from separate hot water and cold water inlets to a common outlet, comprises an outer housing, an inner housing, a lever pivotably mounted in the inner housing and having an outer end projecting through the top wall of the outer housing for coupling to the faucet handle, and a slide valve within the inner housing and coupled to the inner end of the lever. The slide-valve is formed with a first passageway cooperable with two bushings at the two inlets, and a second passageway cooperable with the outlet, such that rotating the handle in the circumferential direction controls the mixture-proportions and thereby the temperature of the water entering the first passageway from the two inlets and passing therefrom via the second passageway to the common outlet; whereas pivoting the handle in the vertical direction controls the flow-rate of the water passing via the first passageway and second passageway to the common outlet.
