摘要:
A scroll compressor includes stationary and orbiting scroll members in engagement with each other. The stationary scroll member includes a stationary end plate having first and second end surfaces opposite to each other, a stationary scroll wrap protruding axially from the first end surface of the stationary end plate, a discharge port defined in the stationary end plate in the proximity of a center thereof, and a recess defined in the stationary end plate on the second surface thereof. A check valve is received in the recess so as to open or close the discharge port. The recess has a shape substantially identical to the shape of the check valve and also has a depth greater than a maximum lift of the check valve.
