Abstract
In a gas compressor, an outline shape of an inner peripheral surface () of a cylinder () is set such that in a point before a first compression chamber (B) adjacent to a second compression chamber (A) in an upstream side in a rotational direction (W) is exposed to a discharge hole () of a primary discharge portion () with rotation of a rotor () in the rotational direction (W) (point where the first compression chamber (B) is positioned upstream of an angular position of being exposed to the discharge hole () of the primary discharge portion ()), a pressure of refrigerant gas (G) inside the compression chamber () reaches a discharge pressure. Therefore, the discharge hole () of the primary discharge portion () always discharges the refrigerant gas (G) from the compression chamber ().
