ABSTRACT:
An improved flushing device is disclosed for use in tanks such as are used for flushing toilets. The flushing device has an inlet means including an improved two-stage valve which uses inlet line pressure in operating each of the two stages. A float is movably mounted on an inlet fixture for use in controlling the tank filling operation with a lever operatively coupling the float to the first stage of the valve. A vertical hollow overflow tube including a bowl filling aperture cooperates with a liquid operated variable buoyancy means on the float and alternatively a tube connects the inlet means with an overflow tube.
