Heat insulating structure of compressor

摘要

A compressor has a suction chamber and a discharge chamber, and compresses refrigerant gas. The compressor includes a cover housing having an inner wall surface. The inner wall surface defines at least one of the suction chamber and the discharge chamber. A heat insulating member covers the inner wall surface. A flow restraining member restrains refrigerant gas from flowing between the heat insulating member and the inner wall surface. Hence, the adiabatic efficiency increases in at least one of the suction chamber and the discharge chamber within the compressor.
