ABSTRACT:
Toilet flushing apparatus for use in a toilet assembly having a drain valve seat, includes a flush valve assembly for enabling a partial flushing operation to occur for conserving the use of water. The flushing valve assembly includes a floating flapper valve device for sealing the drain valve seat, the floating flapper valve device including an air trapping float chamber and an inlet mounted in fluid communication with the chamber for trapping air in the chamber to delay the closing of the flapper device. A vent mounted in fluid communication with the chamber enables at least some of the trapped air to be released from the chamber for enabling the flapper device to close prematurely, thereby causing a partial flush operation to occur. In one form of the invention, a trip lever assembly directly controls the operation of the floating flapper valve device for full flush operations, and it is adapted to control the vent for a partial flushing operation.
