ABSTRACT:
A tank having an outlet conduit is provided with a valve assembly for controlling the flow of a fluid through the outlet conduit. The valve assembly includes a first valve element cooperating with a first valve seat formed by the conduit to provide a first valve. A second valve element cooperates with a second valve seat formed by the first valve element to provide a second valve. Valve opening means are pivotal on the tank to selectively open the second valve or the first and second valve to permit the discharge of fluid volumes of different magnitudes.
Both the first and second valve elements can be heavier than equivalent volumes of the fluid so a first float is provided to maintain the first valve in its open state and a second float is provided to maintain the second valve in its open state. As the surface of the fluid descends, the respective floats close their respective valves at fluid levels dependent upon the initial height of the floats in the tank. The second float can be attached to the valve opening means at any height to control the magnitude of the lesser fluid volume.
