Abstract
Abstract Water is supplied to a water storage tank through a floatactuated fill valve and a primary control valve of a flush control unit which provides for selecting either a full flush or a partial flush of the water in the tank into the toilet bowl. The primary control valve determines whether water flows directly into the tank or to a secondary control valve connected by a tube to a water-actuated cylinder which is effective to close the flush valve member after a partial flush. The secondary control valve is actuated by movement of the float support rod connected to the fill valve and cooperates with the primary control valve to assure proper filling of the bowl after either a full flush or partial flush. The control unit also provides for reversing between a full flush and a partial flush at any time, and for providing anti-siphon protection in the fill line, in addition to accommodating a wide pressure variation in the fill line.
