Abstract
A scroll compressor includes fixed and movable scrolls, and a drive part. The fixed scroll has a fixed-side end plate, a fixed-side lap, and a thrust sliding portion surrounding the first lap. The movable scroll has a movable-side end plate and a movable-side lap. The drive part revolves the movable scroll so that refrigerant in a compression chamber formed by the fixed-side lap and movable-side lap is compressed. A back-pressure space which communicates with the compression chamber for at least a prescribed period in a revolution cycle is formed at the back face side of the movable scroll. A first oil channel supplied with oil from a space is formed in a first angle region of the fixed-side end plate. A communication channel formed in a second angle region communicates with the compression chamber. A second oil channel communicating with the back-pressure space is formed in the second angle region.
