Abstract: A reversible flush valve is presented which may be manually actuated and is self-closing. The valve has a spool valve element, one end of which controls communication between a fluid inlet and a fluid outlet, and the other end of which defines a control chamber. A plug movable between two positions determines the mode or direction of operation of the valve. A passageway through the spool communicates with the control chamber via a flexible valve in the form of a resilient and compressible rubber ring which controls the rate of closing of the valve.
