Patent ID: 8387651

Claim:
A valve assembly for a faucet, said valve assembly comprising: a housing having an inner surface; a spout; a valve stem positioned within said housing; a first valve positioned within said housing and rotatably coupled to said valve stem upstream from said spout such that said first valve does not translate along a longitudinal axis of said valve stem, said first valve selectively positionable to control a flow of fluid from a fluid source to said spout, said first valve comprising a first valve seat and a first valve disc having at least one opening defined therein, said first valve having a radially outermost surface coupled in sealing contact against the inner surface of said housing such that fluid does not leak between the radially outermost surface of said first valve and the inner surface of said housing, said first valve disc is selectively movable to enable fluid to flow through said at least one opening; and a second valve positioned within said housing and rotatably coupled to said valve stem such that said second valve does not translate along the longitudinal axis of said valve stem, said second valve configured to selectively drain fluid from said valve assembly, said second valve coupled to said first valve such that when said first and second valves are positioned in a first operational position, fluid flows from said fluid source through said spout, and such that when said first and second valves are positioned in a second operational position, fluid is substantially prevented from flowing from the fluid source through said spout and residual fluid within said faucet is gravity drained from the faucet, said second valve downstream from said spout when positioned in said first and second operational positions, and said second valve having a radially outermost surface coupled in sealing contact against the inner surface of said housing in the first operational position and the second operational position such that fluid does not leak between the radially outermost surface of said second valve and the inner surface of said housing.
