Abstract
A gravity flush toilet system includes a fixture with a water sealed trap and a tank having an overflow tube, a flush valve and a fill valve. A control assembly includes a float assembly with a member for pushing the flush valve toward its closed position as the water level descends. A full volume or a reduced volume flushing operation is selected by alternatively filling or emptying a bias chamber of the float assembly. Water pressure variations are compensated for by increasing the weight of the float with part of the flow through the fill valve as the tank is emptying. A regulated volume of reseal water is carried in a chamber on the float and is discharged into the overflow tube to refill the fixture trap after each flushing operation.
