Hermetic compressor in super critical refrigeration cycle in vehicle, has heat insulating resin material provided at discharge chamber to directly insulate heat of fluid compressed by compression mechanism

摘要

The circumference of a discharge chamber (257) which is formed from a material different from the material of casing (101), changes with the working pressure of sucked fluid. A heat insulating resin material (290) is provided at the discharge chamber to directly insulate the heat of the fluid compressed by a compression mechanism (200).
