Kind Code:

Abstract:
A toilet flushing device has a body with an inlet and an outlet. There is a valve seat in the body in the flow path between the inlet and the outlet and a valve in the body movable toward and away from the valve seat to control water flow through the toilet flushing device. A handle assembly for causing movement of the valve toward and away from the valve seat includes a socket attached to the body and a handle mounted in the socket for pivotal movement. A plunger is positioned in part within the socket and is in contact with the handle. Pivotal movement of the handle causes axial movement of the plunger with a portion of the plunger being positioned for contact with valve for causing movement thereof. There is a spring for biasing the plunger toward the handle. A bushing is attached to the socket and has a central bore within which the plunger moves. A seal member is attached to the bushing and forms a seal therewith. The seal member has a central passage with the plunger being positioned within this central passage. The seal member has a plurality of spaced inwardly extending circumferential seal lobes which are in sealing contact with the plunger at axially spaced locations thereon. The lobes define at least one recess therebetween and there is lubricant within the at least one recess.
