Abstract
A flow control valve is described comprised of first and second rigid members and a resilient single or multi stage valve element disposed between the rigid members. A fluid flow path is defined through the rigid members and through or around the valve element to provide a continuous flow path through the valve. The rigid members are movable relative to each other between a first position and a second position. The valve element is sufficiently compressed by the rigid members when they are in the first position so as to close the flow path through or around the valve element. The valve element is sufficiently relaxed when the rigid members are in the second position to allow fluid flow through the flow path through or around the valve element.
