Abstract:
Leak preventing means for a toilet flush valve assembly having inlet valve means for controlling flow of water into a toilet flush valve tank, inlet valve control means connected with the inlet valve means to close the inlet valve means following a flush cycle and to permit opening of the inlet valve means upon initiation of a flush cycle, flush valve means for releasing water from the tank to flush a toilet, and flush valve actuator means connected with the flush valve means to open it, said leak preventing means comprising:detent means for preventing opening of the inlet valve means until a deliberate flush cycle is initiated by operation of the flush valve actuator means to open the flush valve means, said detent means including a detent member that is yieldably biased into a first position blocking opening movement of the inlet valve means and a second position moved against the bias to enable the inlet valve means to open, wherein the detent member engages the inlet valve means to hold it closed until the flush valve actuator means is deliberately actuated to initiate a flush cycle; anddetent actuator means connected between the flush valve actuator means and the detent member to move the detent member between its first and second positions independently of operation of the inlet valve control means.
