Claims

[Claims for Utility Model Registration] A rotating shaft, a rotor that is rotated via the rotating shaft, a large number of vanes that are attached to the rotor so as to be freely retractable in a substantially radial direction, and a rotor that houses the vanes. A cam ring, a side plate that holds the cam ring and forms a pump chamber on the inner periphery of the cam ring, and a housing that accommodates the side plate or rotor, and when the rotor is rotated, it is attached to the rotor. The vanes in the cam ring slide while being pressed against the inner peripheral surface of the cam ring, and the volume change between each vane at that time introduces working gas into the pump chamber via the suction passage, pressurizes it, and discharges it to the outside via the discharge passage. and a vane configured to introduce oil or the like in an oil reservoir connected to the discharge passage into the bottom of the vane receiving hole of the rotor through a throttle ring installed between the rotating shaft and the side plate by gas discharge pressure. In the rotary type rotary compressor, the side plate has an oil reservoir that directly supplies oil, etc. from an oil reservoir to the bottom of the vane hole near the small arc where the outer circumferential surface of the rotor approaches the inner circumferential surface of the cam ring, without going through a throttle ring. . 1. A vane type rotary compressor, characterized in that a vane receiving hole near the small arc is independent or almost independent from other vane receiving holes.
