Abstract
Abstract There is disclosed herein a valve assembly principally for use with a tub filler or spout and a spray head. The spout is connected with a fluid supply, and the valve assembly is mounted within the spout. The assembly includes an anti-siphon valve. The valve assembly further includes a button member and seat arrangement for allowing fluid to pass from the inlet to the outlet of the spout or to divert the fluid to a spray head coupled with the valve assembly. Diversion of fluid to the spray head occurs upon operation of the spray head and as a result of a differential pressure operating on components of the valve assembly.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
241 words
A spout assembly comprising spout means having a passageway therethrough, said passageway having an inlet and an outlet, partition means mounted in the inlet of said spout means, said partition means being adapted to be coupled to a fluid supply and having an opening therein communicating with the passageway in said spout means, means defining a drain outlet, said drain outlet being disposed within said passageway and being in axial alignment with said opening in said partition means, valve inlet means disposed within said passageway, said inlet being adapted to communicate with said opening in said partition means, flexible anti-siphon valve means mounted within said spout means between said opening in said partition means and said drain outlet for normally closing said opening in said partition means when no fluid is supplied to said assembly, said antisiphon valve means including a diaphragm normally biased to close said opening in said partition means and having a flexible webbing portion with openings therethrough for allowing said diaphragm to move away from said opening upon supply of fluid to said assembly, said supply of fluid to pass through said openings and said diaphragm to move against said drain outlet preventing fluid flow therethrough and directing said flow to said valve inlet means, said valve means including a rim and said flexible portion intercoupling said rim and said diaphragm, and retaining means coupled with said rim for maintaining said valve means within said spout means.
