A faucet valve 10 includes a ball valve 28 seated in a valve chamber 18. The ball valve 28 has a plurality of apertures 46 circumferentially spaced about the control stem 32 which extends through an opening 60 in the cap assembly 48 of the valve housing 16. A check valve 66 is formed within the hollow interior 62 of the ball valve and includes a disc section 70 that mounts a flap valve 78. A shield formed by a cylindrical wall 80 downwardly depending from the disc section 70 and a snap ring 84 fitted on the lower end of the cylindrical wall protects the flap valve from undue water turbulence. Negative pressure in the supply inlet opens the flap valve 78 to draw air through passageway 64 formed by the apertures 46 and auxiliary opening 60 and hollow interior 62 of the ball valve seated in the valve chamber 18.

A faucet mixing valve characterized by: a housing having a valve chamber and two supply inlets for hot and cold water in communication with said valve chamber, respectively, and a supply outlet having one end adjacent to said valve chamber directly exiting from said valve chamber; a rigid movable valve element within said valve chamber operably movable to selectively cover and uncover said two supply inlets and closing and opening communication to said supply outlet from either of said two supply inlets; said housing including an auxiliary opening to said valve chamber in parallel to said supply outlet and in communication with a passage through said movable valve element forming an anti-siphon air passageway that is parallel and independent of said supply outlet; said air passageway having its distal end open to the atmosphere and is independent of said supply outlet; a one way check valve mounted within said air passageway to prevent fluid from either of said two supply inlets from exiting said auxiliary opening but allowing air to enter from said auxiliary opening into said air passageway and bypassing said supply outlet.
