Seat keeper

A faucet valve cartridge comprising:

• a valve body including an outer wall defining a receiving bore extending axially along a longitudinal axis;
• a valving member supported within the receiving bore of the valve body for rotation about the longitudinal axis of the receiving bore;
• a valve plate positioned within the receiving bore and coupled to the valving member, such that the valve plate rotates with the valving member, the valve plate including a first sealing surface and a first inlet opening offset from the longitudinal axis of the receiving bore;
• a seat including a second sealing surface and a second inlet opening, the first inlet opening configured to be in selective fluid communication with the second inlet opening upon rotation of the valving member and the valve plate;
• a retainer extending intermediate the outer wall of the valve body and the seat, the retainer configured to couple the seat to the outer wall while providing for limited axial movement of the seat relative to the cylindrical wall;
• and
• a biasing member operably coupled to the seat and configured to bias the first sealing surface into sealing engagement with the second sealing surface.

A faucet valve assembly comprising:

• a valve housing including a first bore having a longitudinal axis, a second bore in fluid communication with the first bore, the second bore being laterally offset from the longitudinal axis of the first bore, and an outlet port in fluid communication with the first bore;
• a valve body positioned within the first bore of the valve housing, the valve body including a cylindrical outer wall defining a receiving bore extending axially along the longitudinal axis;
• a valving member supported within the receiving bore of the valve body for rotation about the longitudinal axis, the valving member including an outlet passageway configured to be in fluid communication with the outlet port of the valve housing in at least some of the rotational positions of the valving member;
• a valve plate positioned within the receiving bore and coupled to the valving member, such that the valve plate rotates with the valving member, the valve plate including a first sealing surface and a first inlet opening laterally offset from the longitudinal axis;
• a seat positioned within the second bore of the valve housing, the seat including a second sealing surface and a second inlet opening laterally offset from the longitudinal axis, the first inlet opening configured to be in selective fluid communication with the second inlet opening upon rotation of the valving member and the valve plate;
• a retainer coupled to the seat and to the cylindrical outer wall of the valve body;
• and
• a biasing member operably coupled to the seat and configured to bias the first sealing surface into sealing engagement with the second sealing surface.
