| description | PROBLEM TO BE SOLVED: To provide a scroll compressor with high reliability in which a sliding face of a stationary scroll and a movable scroll is always sufficiently lubricated when a back pressure space is formed around the movable scroll.SOLUTION: A scroll compressor comprises: a stationary scroll 31 having a stationary side mirror plate 311, a stationary side lap 312 and a peripheral edge 313; a movable scroll having a movable side mirror plate and a movable side lap; and a drive motor. The drive motor turns the movable scroll, so as to compress a refrigerant in a compression chamber. A back pressure space intermittently communicated with the compression chamber is formed on the movable scroll back face side. A lower face 313a at a peripheral edge has an always sliding face R1 always contacting an upper face of the movable side mirror plate, an intermittent sliding face R2 intermittently contacting the upper face, and a non-sliding face R3 always facing to the back pressure space. A first oil groove 313d supplied with oil from an oil storage space communicated with a compression chamber on a center side is formed on the always sliding face. A second oil groove 313e extending from the intermittent sliding face to the always sliding face is formed on an outer side than the first oil groove. |
