Abstract

See full text

A diverter valve 10 has a two piece housing 22 including a lower member 24 and an upper member 26 securely snap fitted together within a cavity 12 of a faucet body 14. The housing 22 has a piston valve assembly 28 slidably mounted therein for movement between a first position which allows water to flow through a spout and a second position which allows water to flow to a spray head. The diverter valve has prongs 72 which resiliently bias the spool assembly 28 to the first position to reduce chattering of the valve assembly and to provide a back-up anti-siphon system.
