PROBLEM TO BE SOLVED: To ensure sealability of a seal part of a check valve, without complication of machining of a shell.SOLUTION: A seal part 41s extends in an arc manner along the inner peripheral surface of a rear housing 12. Then, by arranging the arc-shaped seal part 41s along the arc-shaped inner peripheral surface of the rear housing 12, refrigerant is prevented from flowing back in valve closing of a check valve 40. With this constitution, compared to a case where the seal part 41s is formed into a flat surface shape, the seal part 41s easily contacts with the periphery of a suction port 22 on the inner peripheral surface of the rear housing 12. Consequently, a compressor eliminates such machining that a portion with which the seal part 41s on the inner peripheral surface of the rear surface 12 contacts is formed into the flat surface shape.SELECTED DRAWING: Figure 5 |
