Abstract
A gas compressor includes a block part inside which a cylinder chamber is formed; a rotor rotatably housed in the cylinder chamber; and vanes provided on an outer circumferential portion of the rotor. The block part has a pressure supply part configured to supply pressure to backpressure spaces behind the vanes. This pressure supply part has an intermediate-pressure supply part which communicates with each backpressure space from an intake cycle to a compression cycle in the compression chamber, a first high-pressure supply part which communicates with the backpressure space from the compression cycle to a discharge cycle in the compression chamber, and a second high-pressure supply part which is formed between the intermediate-pressure supply part and the first high-pressure supply part independently of the first high-pressure supply part and which communicates with the backpressure space in a middle of the compression cycle in the compression chamber.
