Abstract
A check valve includes a valve seat portion and a reed valve element and is received in a receiving hole of an intermediate pressure refrigerant supply passage that is placed adjacent to a flow inlet of an injection port, through which a refrigerant of an intermediate pressure is injected into a compression chamber. A center of the flow inlet of the injection port is offset from a central axis of a valve seat passage formed in the valve seat portion.
