ABSTRACT:
The flapper valve is to be utilized in a compressor of the type having a valve chamber adjacent a discharge or outlet port. The valve comprises a flexible valve member in the valve chamber which has a port closure at the front end thereof to seal the discharge port of the compressor. A backer plate is similarly received in the valve chamber and has one end in engagement with the rear end of the valve member to normally bias the port closure to a position wherein the discharge port of the compressor is closed. The valve member is provided with forwardly extending arms which cooperate with upturned ears on the backer plate to prevent longitudinal and lateral movement of the valve member. Accordingly, the valve member and backer plate need not be connected together prior to placement into the valve chamber. Alternatively, if the member and plate are connected together, their relative positions will be maintained even if the connection breaks.
