Claims

[Scope of utility model registration request]

A rotor is rotatably mounted horizontally in a cylinder chamber formed by a cylinder and both side plates attached to both sides of the cylinder, and the vanes are slid approximately radially into multiple vane grooves formed in this rotor. In a single-vein type compressor, the gas is freely installed, and as the rotor rotates, gas is sucked in from the suction port, compressed, and discharged from the discharge port. A small high-pressure oil supply hole that communicates with the high-pressure oil passage is opened at a position facing the vane groove bottom space when passing nearby, and a vane groove bottom space in the above state is provided on both end surfaces of the rotor, concentric with the rotor axis. A ring-shaped groove is formed at a position outside of the ring-shaped groove, and a large-diameter deep hole communicating with the medium-pressure oil passage is formed in both side plates at a position not facing the bottom space of the vane groove in the above-mentioned state. A vane type compressor, characterized in that the opening is made to face a concave groove and a band formed by rotating the vane groove bottom space in the above state around a rotor axis.
