Abstract: A float valve assembly for a water closet that has perfect seating control. The float valve can only move in an up and down direction and cannot move sideways. The float valve assembly has a float member that forms a valve which cooperates with a valve seat for opening and closing the flushing opening of the outlet coupling of the water closet. A pair of laterally spaced wire arm members have their one end pivotally attached to the top of the float member and their other end are pivotally attached to a C-shaped clamp that snaps onto the overflow tube within the water closet. A string-like member has its one end attached to the top of the float member and its opposite end can be attached to the free end of the actuating arm within the water closet.

Abstract: A toilet tank flush valve assembly including a vinyl foam valve closure element is disclosed. A guide element is attached to the bottom of the valve closure element and extends into the flush pipe when the valve closure element is seated for guiding the seating of the valve closure element. A linkage element links the bottom of the valve closure element to the inside of the flush pipe below the valve seat for limiting upward vertical movement of the valve closure element and for limiting revolution of the valve closure element about the overflow pipe when the valve closure element is lifted off of the valve seat so that the bottom extremity of the guide is not moved horizontally to a position that is not within the valve seat.A vinyl foam disc-shaped buoy is attached to the top of the valve closure element by a ball chain and is restrained from moving more than a predetermined length of the chain from the valve closure element.
