Flush water valve assembly

Claim 1

A flush water valve assembly of the class described comprising: a. a flush water valve seat means having an integral radial spider in axial alignment therewith fixedly mounted in the flush water outlet passage of the bottom wall of a water reservoir tank and an upstanding vertical valve guide blade means fixedly mounted on said spider in axial alignment therewith, b. a cylindrical movable flush valve means having an upstanding cylindrical tubular element extending above the water level in the reservoir prior to the flush release and slidably mounted on said valve guide blade means and in frictional engagement therewith, a ring float chamber having a flat bottom surface mounted on the lower end of said tubular element and an elastomeric flush valve means removably mounted over the bottom surface of said ring float means in water seal alignment with said valve seat means and having a valve opening hook means adjacent to the top of said tubular element, c. said guide blade means having integral guide blades spaced apart and extending upwardly from said spider to just below the top of said tubular element prior to the flush release thereof, d. said guide blades having like recesses along the adjacent inner top edges thereof extending downwardly and having shoulders therein adjacent their midpoint and forming an axially aligned opening therein, e. a water replenishing after flush trap seal refill tube fixedly mounted in said opening adjacent said shoulders and extending above the tops of said tubular element and guide blade means, f. a nippled cap ring valve control means removably mounted on the upper end of said water refill tube and having a substantially flat upper surface and an integral nipple on its lower surface, the said cap ring having an outside ring diameter of at least equal to the outside diameter of said tubular element thereby limiting the upward movement thereof when the valve is open and a nipple and ring inside diameter sufficient for mounting on said refill tube and to receive an after flush water supply refill tube for replenishing the water supply in the trap of the plumbing fixture.
