Abstract
A scroll compressor includes a compression mechanism having a fixed scroll and an orbiting scroll. The fixed scroll includes a first end plate, an outer peripheral wall extending from an edge of the first end plate, a first oil groove, and a first wrap inside of the outer peripheral wall. The orbiting scroll includes a second end plate in sliding contact with an end of the first wrap and an end of the outer peripheral wall, a second oil groove, and a second wrap. The first oil groove is disposed on a surface of the outer peripheral wall, extends along an inner periphery of the outer peripheral wall, and is configured to receive lubricating oil at a high pressure corresponding to a discharge pressure of the compression mechanism. The second oil groove is disposed on a surface of the second end plate, and is communicatable with the first oil groove.
