Claims

[Scope of utility model registration request]

(1) In a rotary compressor in which a freely rotatable rotor is horizontally suspended in a cylinder chamber formed in a substantially elliptical shape, and a plurality of vanes are provided that can move forward and backward in the radial direction of this rotor, a pair of adjacent '' 1. The relative closed position of the nearly crescent-shaped compression chamber formed by the vane and the cylinder interior wall with respect to the intake port. A gas compressor characterized in that the maximum confinement position is appropriately shifted in the rotational direction of the rotor.

(2) The scope of the utility model registration claim, characterized in that a communication groove is formed in the inner wall of the cylinder chamber, one end of which communicates with the intake boat, and the other end of which extends toward the advancing side of the rotational direction of the rotor. The gas compressor according to item 1.

(3) The gas compressor according to claim 1, which is a registered utility model, characterized in that a chamfered portion that slopes toward the rear in the rotational direction is provided on the contact surface of the vane tip with respect to the inner wall of the cylinder.
