Docket No. 2111-WF A B S T R A C T A delivery valve assembly, especially for a rotary mechanism, such as a compressor, disposed within a valve chamber of a peripheral wall of a housing, which includes a stop disposed within the chamber, a valve seat formed in an end-wall disposed across an outer end of the chamber, and a movable valve element having an open and closed position. The valve element is generally rectan- gularly shaped in cross-section and comprises a resilient plannar inner portion disposed against the valve seat when it is closed and against the stop when opened. Springs, in the form of a pair of strips are fixedly attached at one end to the peripheral wall and extend across the outer end of the chamber, are attached at their other ends to the inner portion via a pair of side portions. These side portions are resilient and are in substantially opposed relationship. In operation, the springs normally bias the inner portion against the valve seat to its closed position, but when the valve is opened, the inner portion is moved away from its seat until it is disposed against the stop permitting flow to enter and pass through the valve chamber.
