发明名称 BALL VALVE FOR A FAUCET
摘要 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). <IMAGE>
