PROBLEM TO BE SOLVED: To solve a problem that oil supply quantity is slightly more than optimum supply quantity and required hose power of a compressor is large in a conventional vane rotary type compressor and provide a stable quality and low cost compressor reducing required hose power by optimizing oil supply quantity. SOLUTION: In this invented compressor 1, a restriction passage 17a is provided in a part of an oil supply passage 19b supplying oil from an oil reservoir chamber 5b to a vane back pressure control device 22. The restriction passage 17a is provided on a gasket 17 put between a compression mechanism and a high pressure case 5 and sealing high pressure fluid and oil. Width and length of the restriction passage provided on the gasket 17 is optimized to reduce oil supply quantity and required hose power of the compressor 1 can be reduced.
