PROBLEM TO BE SOLVED: To reduce production cost of a gas compressor by eliminating parts such as an ejection valve.SOLUTION: A housing 60 stores a compressor body 60 having a rotor 50 rotating around the axis C, a cylinder 40, three plate-like vanes 58, a front side block 20, and a rear side block 30. An ejection chamber 14 is formed in the housing 10 for ejecting a high pressure refrigerant gas G (gas) ejected from the compressor body 60. A plurality of compression chambers 43 are formed so as to be partitioned with the rotor 50, the cylinder 40, the side blocks 20, 30 and two vanes 58, 58. A notch 54 and ejection holes 38, 39 (ejection passages) are formed in a predetermined rotation angle range around the axis C of the rotor 50, so that the compression chambers 43 and the ejection chamber 14 communicate with each other, to eject the refrigerant gas G from the compression chambers 43 to the ejection chamber 14 through the ejection passage in the predetermined rotation angle range. |
