PROBLEM TO BE SOLVED: To provide a compressor capable of improving COP. SOLUTION: A rear head 38 of the compressor has a discharging port 38e discharging a coolant compressed by the rotation movement of a roller in a cylinder chamber, and a recessed portion 38g formed at a part opposite to a discharging valve 54 for opening and closing the discharging port 38e. The thickness TA12 of the discharging port 38e of the rear head 38 is smaller than the thickness of a discharging port of a front head. The depth D12 of the recessed portion 38g of the rear head 38 is smaller than the depth of a recessed portion of the front head. COPYRIGHT: (C)2009,JPO&INPIT
