Claims

[Claims for Utility Model Registration] (1) A cylinder block with an elliptical inner circumference, front and rear side blocks attached to both sides of the cylinder block, and a cylinder interior constituted by the cylinder block and both side blocks. a rotor that is rotatably suspended horizontally on the rotor and has a plurality of vanes that can move forward and backward in the radial direction;
It consists of a substantially disc-shaped control plate disposed between the front side block and the cylinder block and rotatably mounted within a predetermined angle, and the control plate is rotated according to the suction pressure in the suction chamber. In a gas compressor, the capacity of the compression work chamber is variable according to the operating condition by continuously moving the suction port of the control plate that communicates the communication hole formed in the front side block with the cylinder chamber. In order to introduce oil from the compressor side into the rotor shaft of the rotor, an oil supply path is provided that supplies oil from an oil communication hole formed in the front side block to an oil filling groove formed on the periphery of the control plate. A gas compressor characterized in that a front side block and a control plate are connected to each other, and the oil introduced into the oil filling groove airtightly seals between the periphery of the control plate and the front side block. (2) The gas compressor according to claim 1, wherein the peripheral edge of the control plate is tapered so that the thickness gradually decreases toward the end.
