PROBLEM TO BE SOLVED: To improve efficiency (COP) in a gas compressor.SOLUTION: A compression chamber 43A partitioned by a rotor 50, a cylinder 40, both side blocks 20 and 30, and a vane 58, includes a compressor body 60 constituted to execute suction, compression and discharge only by one cycle in a period of one rotation of the rotor 50, and a housing 10 covering the compressor body 60; and a cross-sectional contour shape of an inner peripheral face 41 of the cylinder 40 is formed in a manner that (1) a region in which a volume of the compression chamber 43A is suddenly increased, (2) a region in which the volume of the compression chamber 43A is suddenly decreased, (3) a region in which a volume reduction rate of the compression chamber 43A is smaller than a volume reduction rate in the region (2), and (4) a region in which the volume reduction rate of the compression chamber 43A is larger than the volume reduction rate in the region (3), are successively connected. |
