Abstract
A toilet flushing mechanism includes a dual flush device for effecting both a short flush cycle and a long flush cycle in a toilet tank including a flush valve actuated by an actuation arm.
A cam operable by a handle is rotatably supported adjacent the actuation arm. When rotated in a first direction, the cam acts to press against and pivot the actuation arm to effect the long flush.
When rotated in the second direction, the cam acts to press against and pivot said actuation arm to effect the short flush. A lever is pivotably supported with respect to the actuation arm and pivots between a first position out of blocking contact with the actuation arm and a second position where the lever blocks return of the actuation arm for a predetermined period of time when the cam is rotated in the second direction. A float is coupled to the lever for determining the predetermined period of time. The float acts to pivot the lever into the second position when the cam is rotated in the second direction. Where the toilet tank includes an overflow tube and a water control there is a trapway reseal device for the toilet tank. The trapway reseal device includes a float slidably supported along the overflow tube to move with the changing level of water in the tank as the tank is flushed and refilled. A reseal hose receives water from the water control and includes a free_ end coupled to the float. The reseal hose selectively directs water into at least one of the tank and the overflow tube dependent upon the position of the float as determined by the level of water in the tank.
