A scroll compressor includes fixed and movable scrolls and a crank shaft coupled to the movable scroll. The fixed and movable wraps are engaged to form a compression chamber. A refrigerant compressed in the compression chamber is discharged from a discharge port open at a central portion of the fixed end plate. The compression chamber is divided into first and second compression chambers facing outer and inner circumferential surfaces of the movable wrap. One of the end plates is provided with a communication groove recessed at a portion near a wrapping start position of the wrap. The communication groove connects the first compression chamber and the discharge port before the outer circumferential surface of the movable wrap, which is eccentrically rotating while sliding on an inner circumferential surface of the fixed wrap, separates from the inner circumferential surface of the fixed wrap. |
