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.
Claims18
An automatic flush valve for delivering a predetermined amount of water upon each acutation thereof comprising a closed casing having an inlet for water under pressure and an outlet, a valve comprising a plate for closing said outlet mounted for sliding movement across said outlet and having an opening therethrough movable into alignment with said outlet for affording the passage of water through said outlet, said opening having a leading edge and a trailing edge, actuator means for sliding said plate from its outlet closing position a predetermined distance across said outlet to a position wherein said leading edge has moved to effect a partial opening of said outlet, and driving means dependent upon the resulting passage of water through said valve for sliding said plate in the same direction as by said actuator means until said trailing edge passes said outlet to close said valve and stop the flow of water.
A dual capacity flush vlave comprising a closed casing having a water inlet and a water outlet, a valve member movable from a fully closed position to a fully open position, means providing a water passage between said inlet and said outlet and a water motor positioned within said passage for rotation by water passing therethrough, means connecting said motor to drive said valve member in a predetermined direction, an actuator for selectively moving said valve member to a first open position and alternatively to a second more open position, said actuator upon moving said valve member to either of said positions effecting the supplying of water to said motor for driving said valve member to its closed position whereby movement of said member to said first position allows a greater volume of water to flow before closing said valve than that resulting from the movement of said valve member to said second position.
A dual capacity fluch valve comprising means providing an inlet for water under pressure and an outlet, a rotatable valve member positioned between said inlet and said outlet and having an opening therethrough for controlling the flow of water from said inlet to said outlet, a closed casing for said rotatable member, a valve actuator movable alternatively to either of two flush actuating positions, means connecting said actuator and said rotatable valve for effecting rotation of said valve in the same direction on movement of said valve to either of said positions, movement of said valve to one of said positions opening said valve a first predetermined amount and to the other of said positions to a second and greater predetermined amount, and power means dependent upon a flow of water from said inlet to said outlet for rotating said valve in the same direction to close said valve, the aggregate amount of water flowing to said outlet being greater for said one position of said valve than for said other position.
