<p>Provided is a highly reliable scroll compressor where oil is supplied to an entire sliding portion of the scroll even when a back-pressure space is formed and a communication channel which allows communication between a compression chamber and a back-pressure space communicate is formed in a fixed scroll. The scroll compressor is equipped with: a fixed scroll (31) having a fixed-side end plate (311), a fixed-side lap (312), and a peripheral portion (313); a movable scroll having a movable-side end plate and a movable-side lap; and a drive motor. The drive motor 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 intermittently communicates with the compression chamber is formed at the back face side of the movable scroll. On a sliding face (R1, R2) in the peripheral portion, which slides with the movable-side end plate, a first oil channel (313d) supplied with oil from an oil-retention space is formed in a first angle region (A1) with respect to the centre of the fixed-side end plate, and a communication channel (314) allowing communication between the back-pressure space and the compression chamber and a second oil channel (80) communicating with the back-pressure space are formed in a second angle region (A2) with respect to the centre of the fixed-side end plate.</p> |
