<P>PROBLEM TO BE SOLVED: To provide a compressor in which a refrigerating machine oil is applied smoothly on a surface, and which reduces a leakage loss of a refrigerant. <P>SOLUTION: A swing compressor 1 includes an oscillating piston 21 and a cylinder 27a which relatively move in cooperation with each other to compress the refrigerant. While the swing compressor 1 is driven, a part where the oscillating piston 21 and the cylinder 27a come close to each other is covered with coating layers 60a, 60b, and 70a of which a contact angle with the refrigerating machine oil is ≤25 degrees. <P>COPYRIGHT: (C)2013,JPO&INPIT |
