ABSTRACT:
A dual capacity flush valve comprises a rotatable valve plate arranged in a sealed housing through which water passes from a supply to the flush outlet. The valve plate has openings which are moved to register with the water outlet and an actuator is provided for vertical movement to either of two open positions of the valve, a downward movement of the actuator for a small quantity flush and an upward movement for a full flush. The flush volume for each position is adjustable. A water motor driven by the flow of flush water returns the valve plate to closed position, stopping its operation when the flow of water is stopped.
