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. The buoy prevents the valve closure element from seating during an interval from when the valve closure element has been lifted from the valve seat until the water level in the toilet tank recedes to less than approximately the predetermined length above a valve seat. A weight is attached to the bottom of the valve closure element for forcing the valve closure element to seat when the buoy does not prevent the valve closure element from seating.
