An oil passage of a centrifugal compressor includes a first oil passage that communicates with an oil pan and a speed increaser chamber to supply oil to a speed increaser and the seal. A second oil passage communicates with the speed increaser chamber. A third oil passage extends upward in a gravitational direction from an end of the second oil passage. A fourth oil passage extends in a horizontal direction and causes the oil pan and an end of the third oil passage to communicate with each other. A pressure relief passage that communicates with an outside is arranged in at least one of a portion of the fourth oil passage through which a gas layer passes and a portion of the oil pan in which the gas layer is stored.

Centrifugal compressor and method for manufacturing centrifugal compressor

A lubricating oil composition for refrigerator including a base oil and an acid scavenger, and a compressor using the composition are provided, where the acid scavenger is a polyalkylene glycol derivative represented by a formula (1) as follows:R&#x2014;[(OR)&#x2014;OR]&#x2003;&#x2003;(1) and the base oil is at least one compound selected from a group consisting of polyvinyl ether, polyalkylene glycol and an ether-base compound represented by a formula (2) as follows,R-[(OR)-(X)&#x2014;(OR)-R&#x2003;&#x2003;(2)where meanings of respective signs are as described in the specification.

Lubricant composition for refrigerating machine and compressor using the same

To provide a sliding member that exhibits excellent durability and is free of lead. A swash plate for a compressor as the sliding member of the invention contains a base material having on the surface thereof a sliding layer constituting at least a sliding surface, on which shoes slide. The sliding layer contains a first layer that contains an amorphous hard carbon (diamond-like carbon) film containing Si (DLC-Si film) and is formed on the base material, and a second layer that is formed on the first layer and contains polyamideimide (PAI) containing a solid lubricant such as MoS.
