Claims

[Scope of Claim for Utility Model Registration] 1. Vanes are fitted into vane grooves drilled in the radial direction on the circumferential surface of a rotor housed in a pump body which is housed in a housing and has side blocks attached to both ends of a cam ring. the vanes slide into sliding contact with the inner circumferential surface of the cam ring due to the centrifugal force of the vanes as the rotor rotates, and as the rotor rotates, a compression chamber defined by the inner circumferential surface of the cam ring, the outer circumferential surface of the rotor, and the vanes is expanded. Alternatively, in a vane type compressor that compresses and suctions refrigerant and discharges the compressed refrigerant into a discharge chamber defined between the housing and the pump body, each end surface of the cam ring and each end surface of these A vane type compressor, characterized in that a groove substantially along the compression chamber is provided on at least one of the abutting surfaces of each of the abutting side blocks and at a location where there is a large pressure difference between the inside and outside of the pump body. 2. The vane type compressor according to claim 1, wherein a portion of the pump body where the pressure difference between the inside and outside is large is a suction port for sucking the refrigerant of the compression chamber. 3. A claim for registration of a utility model, characterized in that the groove is located outside the suction port of the compression chamber, extends along the circumferential direction of the suction port, and is longer than the length of the suction port in the circumferential direction. A vane type compressor according to item 1 or 2.
