PROBLEM TO BE SOLVED: To reduce time for which a movable scroll inclines while a scroll compressor operates, and to realize improvements in efficiency and reliability of the scroll compressor.SOLUTION: A scroll compressor (1) comprises a compression mechanism (14). In the compression mechanism (14), a compression chamber (50) is formed by engagement of laps (42, 52) of a fixed scroll (4) and a movable scroll (5). In the compression mechanism (14), a fixed-side slide-contact surface (84) of the fixed scroll (4) slidably contacts a movable-side end plate portion (51) of the movable scroll (5). A high pressure path (90) is formed in the fixed scroll (4). The high pressure path (90) has one end opening to the fixed-side slide contact surface (84) and the other end communicating with a high pressure chamber (45). As the movable scroll (5) inclines, high pressure gas refrigerant emitted from the high pressure path (90) flows into a second back pressure space (24) to raise a pressure of the second back pressure space (24). As a result, a pressing force acting on the movable scroll (5) increases. |
