Patent ID: 7210498

Claim:
A water limiting, automatic shutoff, back flow prevention, toilet fill flo-control valve ( 32 ) for use with a flush toilet tank ( 10 ) comprising: a flo-control body ( 66 ), a flo-control cover ( 72 ), said flo-control cover ( 72 ) being sealed to said flo-control body ( 66 ) so as to be capable of mounting below a water line in the toilet tank ( 10 ), a flo-control valve stopper ( 58 ) means mounted within said flo-control body ( 66 ) for shutting off or permitting water flow, a hold/release lever ( 110 ) means to hold said flo-control valve stopper ( 58 ) means open, and release the flo-control valve stopper ( 58 ) means to a closed position, a drive impeller ( 80 ) means mounted in said flo-control body ( 66 ) for producing rotational energy, an impeller drive flow chamber ( 68 ) means for directing flow of water to drive said drive impeller ( 80 ) means, a means for gearably coupling rotational energy from said drive impeller ( 80 ) means to said hold/release lever ( 110 ) means, an inlet means ( 36 ) attached to said flo-control body ( 66 ) for mounting said flo-control body ( 66 ) in the flush toilet tank ( 10 ) and providing a connection to a source of water ( 34 ) under pressure, a particle screen means ( 40 ) for screening foreign particles from entering said inlet means ( 36 ), a back flow check ball ( 46 ) means for preventing back flow within said inlet means ( 36 ), an outlet means ( 120 ) on said flo-control body ( 66 ) for coupling to a float valve ( 122 ) or to a water delivery chamber ( 125 ) means, a replenish tube ( 30 ) means to replenish the water level in a toilet bowl ( 12 ) during flush when said water delivery chamber ( 125 ) means is used, a replenish tube clip ( 132 ) means for attaching said replenish tube ( 30 ) means to a toilet over flow tube ( 26 ), a delivery chamber outlet ( 128 ) means for directing water from said water delivery chamber ( 125 ) means to and towards the bottom of the toilet tank ( 10 ) for fill up, an actuator lever ( 104 ) means for initiating operation of said flo-control valve ( 32 ), an actuator lever flush extension ( 106 ) means to link the actuator lever ( 104 ) means to a toilet flush rod ( 16 ) means, whereby when said toilet flush rod ( 16 ) means is depressed said actuator lever ( 104 ) means will open said flo-control valve stopper ( 58 ) means, and cause said hold/release lever ( 110 ) means to hold said flo-control valve stopper ( 58 ) means open allowing flow of water to rotate said drive impeller ( 80 ) means thereby retracting said hold/release lever ( 110 ) means allowing said flo-control valve stopper ( 58 ) means to close terminating the flow of water after allowing a predetermined volume of water to pass through the flo-control valve ( 32 ).
