Abstract: A leak preventing detent apparatus for a toilet flush valve assembly in which an inlet valve (13) to a toilet flush tank (11) is controlled by an inlet valve control device (14, 14a, 16, 17), and an outlet flush valve (21) is controlled by a flush lever (19). The detent apparatus includes a follower member (28) that is moved in response to movement of the flush lever at the initiation of a flush cycle, and a detent (25) that is operative to prevent opening of an inlet valve (26) except when a flush cycle is deliberately initiated. In a preferred form of the invention, a primary inlet valve (26) is provided upstream of the usual inlet valve (13) that is controlled by an inlet valve control device, such as a float (14, 14a, 16, 17), and the detent apparatus effectively cooperates with the primary inlet valve to maintain it closed unless a flush cycle is deliberately initiated. The detent member may be hydraulically damped (37-42) to provide a timed delay of its movement into inlet valve closing position. In the preferred form of the invention, the leak preventing apparatus is capable of preventing inflow of water into a toilet flush tank regardless of the position or condition of the inlet valve control device, or the outlet flush valve from the tank, or the usual water inlet valve, unless the flush lever is operated to deliberately initiate a flush cycle. In another form of the invention, the detent member (45, 58, 65, 80, 90, 100) acts directly on the inlet valve (13) to maintain it closed until a flush cycle is deliberately initiated.

The detent apparatus includes a follower member that is moved in response to movement of the flush lever at the initiation of a flush cycle, and a detent that is operative to prevent opening of an inlet valve except when a flush cycle is deliberately initiated. In a preferred embodiment, the detent member acts directly on the inlet valve to maintain it closed until a flush cycle is deliberately initiated. The detent member may be hydraulically damped to provide a timed delay of its movement into inlet valve closing position. Further, in some forms of the invention a primary inlet valve is provided upstream of the usual inlet valve that is controlled by an inlet valve control device, such as a float, and the detent apparatus effectively cooperates with the primary inlet valve to maintain it closed unless a flush cycle is deliberately initiated. In the preferred form of the invention, the leak preventing apparatus is capable of preventing inflow of water into a toilet flush tank regardless of the position or condition of the inlet valve control device, or the outlet flush valve from the tank, or the usual water inlet valve, unless the flush lever is operated to deliberately initiate a flush cycle.
