Abstract
A vane-type compressor includes a rotor shaft that includes rotating shaft portions and a rotor portion, which are integrated with one another. A lower end of the rotating shaft is disposed in an oil reservoir. The vane-type compressor also includes vane aligners disposed at both end portions of vanes, and recess portions, which are respectively formed in a frame and a cylinder head so as to be concentric with an inner circumferential surface of a cylinder. Outer circumferential surfaces of the vane aligners are slidably supported by the recess portions. In the rotor shaft, oil supply channels, which allow communication between the oil reservoir and the recess portions of the frame and the cylinder head, and an oil pump, which supplies refrigerating machine oil in the oil reservoir to the oil supply channels, are provided.
