MULTISTAGE COMPRESSOR

摘要

A multistage compressor, wherein the refrigerant compressed by a pre-stage compression element (30) is delivered from a noise reducing chamber (35) into an enclosed container (10), led to a post-stage compression element (40) through a post-stage side connection pipe (16) while cooling a motor (20), and delivered to the outside of the compressor after compressed by the post-stage compression element (40), whereby the motor (20) can be cooled with a simple structure.
