ABSTRACT:
A flush valve for a conventional toilet which replaces the conventional flapper valve assembly and seat and operates in conjunction with the standard ballcock valve. A hollow annular drain stopper seat is connected to the upper end of a male threaded cylindrical shank secured in the drain outlet opening of the tank that communicates with the bowl. A stopper fits in a central passage of the drain stopper seat and may be lifted so that water from the tank drains into the bowl through the central passage. At the same time, high pressure water is injected downwardly and tangentially into the central passage through a plurality of circumferentially spaced orifices in the interior cylindrical wall of the drain stopper seat. Water is supplied under pressure from the ballcock valve through a filler hose to an upper pressure chamber in the drain stopper seat that communicates with the orifices. When the stopper descends to seal the central passage in the drain stopper seat, the orifices are located so that the water therefrom refills the tank. The lower end of an overflow tube communicates with the central passage in the shank so that water supplied from the standard refill hose of the ballcock valve can refill the bowl with standing water to provide a trap seal.
