MULTISTAGE COMPRESSOR

摘要

Refrigerant compressed by a first stage compression elements (30) run by a motor (20) is discharged in the closed container (10) via a silencer chamber (35) to cool the motor (20) before the refrigerant is led to a second stage compression element (40). The refrigerant is discharged from the second stage compression element (40) out of the compressor after it is further compressed in the second compression element (40). Thus, the motor (20) is cooled in a simple cooling mechanism during normal operation of the compressor.
