通するようにしたことを特徴とする気体圧縮機。[Claims for Utility Model Registration] A cylinder block with a substantially elliptical inner periphery provided between the side blocks on both sides, and a cylinder rotatable within a cylinder chamber formed by the cylinder block and both side blocks.
In a rotary vane type gas compressor, the rotor is provided with a groove-like recess in the radial direction, and a vane is formed with a vertical groove that can move forward and backward into the groove-like recess and reaches the lower end of the surface in the rotation direction. The side block is provided with a communication hole in which one opening is opened at a position corresponding to the bottom of the groove-like recess, and the other opening is opened to the intake side, so that the vane is in the suction process. A gas compressor characterized in that when the bottom portion and the cylinder chamber are in a disconnected state, the bottom portion and the communication hole communicate with each other.
