Document Type and Number:
Japanese Patent JP7405382
Kind Code:
B2
Abstract:
Provided is a compressor in which friction loss between sliding surfaces that slide against each other can be effectively and stably mitigated over the long term, and a refrigeration cycle device utilizing said compressor. A refrigeration cycle device according to one embodiment of the present invention comprises a compressor, a radiator connected to the compressor, an expanding device connected to the radiator, and an evaporator connected to the expanding device, said compressor having a compressor mechanism that sucks in and ejects a working fluid. Of a first sliding surface and a second sliding surface of the compressor mechanism which slide against each other, a polymer brush is provided to the second sliding surface, which has a smaller surface area than the first sliding surface.
