摘要： A scroll compressor (1) of the present invention includes a pressing mechanism (75) and a back-flow prevention mechanism (35). The pressing mechanism (75) includes a back-pressure chamber (53) facing a back surface of a movable-scroll end plate (71), and a back-pressure supply path (80) for allowing the back-pressure chamber (53) to communicate with a compression chamber (23) which is in a state right before the compression chamber (23) communicates with an outlet port (64) or a state in which the compression chamber (23) communicates with the outlet port (64). The back-flow prevention mechanism (35) allows refrigerant of the back-pressure supply path (80) to flow from the compression chamber (23) to the back-pressure chamber (53), and prevents fluid of the back-pressure supply path (80) from returning from the back-pressure chamber (53) to the compression chamber (23).

摘要： A compressor (1) prevents lubrication oil from leaking from a lower end of a bearing (3) and flowing out from a casing (5). The compressor (1) includes a compression mechanism (7), a drive shaft (11), a bearing (3) for the drive shaft (11), and an oil supply passage (29) configured to supply lubrication oil to a clearance between the drive shaft (11) and the bearing (3). The drive shaft (11) includes a large-diameter shaft part (11f) supported by the bearing (3), and a small-diameter shaft part (11g) connected to a lower end part of the large-diameter shaft part (11f). A sealing part (10) configured to reduced or prevent oil leakage from the bearing (3) includes an oil receiving surface (26) facing a circular stepped surface (12) formed at a boundary between the large-diameter shaft part (11f) and the small-diameter shaft part (11g) and being apart from the stepped surface (12) with a clearance.

摘要： An oil groove (80) on a fixed scroll is disposed on a surface, of an outer peripheral wall (63) of a fixed scroll (60), that is in sliding contact with an end plate (71) of an orbiting scroll (70). The oil groove (80) on the fixed scroll extends along an inner periphery of the outer peripheral wall (63). The oil groove (80) on the fixed scroll receives lubricating oil at a high pressure corresponding to a discharge pressure of a compression mechanism (40). An oil groove (83) on the orbiting scroll is disposed on a surface, of the end plate (71) of the orbiting scroll (70), that is in sliding contact with the outer peripheral wall (63) of the fixed scroll (60). The oil groove (83) on the orbiting scroll can communicate with the oil groove (80) on the fixed scroll.
