PROBLEM TO BE SOLVED: To provide a gas compressor in which super compression inside a compression chamber is prevented and a structure of an oil separator disposed in a compressor body or outside the compressor body is simplified.SOLUTION: A gas compressor is provided with: a compressor body 60 having a compression chamber 43, which is partitioned by a rotor 50, a cylinder 40, side blocks 20, 30 on both sides, and vanes 58, formed in such a manner that only a single cycle is carried out during a single rotation of the rotor 50; and a cyclone block 70 that isolates a refrigerant oil R as a refrigerant gas G passes. In the cylinder 40, when the pressure inside the compression chamber 43 reaches a discharge pressure in a previous stage in which the compression chamber 43 faces a first discharge part 45, a second discharge part 46, which discharges the refrigerant gas G, is formed, and a communication path 39, which allows a discharge chamber 45a of the first discharge part 45 and a discharge chamber 46a of the second discharge part 46 to communicate each other, is formed further upstream side of the refrigerant gas G flow than the cyclone block 70. |
