Abstract
A diverter valve assembly (10) has a one piece valve seat member (26) that is fitted within a cavity (12) of the faucet body (14). The one piece valve seat member has a flexible peripheral lip (62) with an annular recess (64) that allows fluid to pressurize and exert an outward force on the lip to move the lip and seal it against the valve cavity. Furthermore, the one piece valve seat member has prongs (44) which resiliently bias the spool assembly (28) to a first position to reduce chattering of the valve assembly and to provide an anti-siphon system. A cup valve (36) has a thin peripheral lip (76) at an end of a peripheral section (75) that is about a tubular inner section (78) that has a narrow annular groove (79) therebetween which limits collapse of the cup valve (36) during operation thereof as a pressure responsive piston to move the valve element (34) to a closed position.
