Compressor

Abstract

A compressor ( 10, 100 ), comprising a compressor housing ( 15 ), a drive mechanism ( 12 ), and a compressing unit ( 14 ) having one or several compression levels ( 14 - 1, 14 - 2 ) for compressing a cooling agent, wherein the compressor ( 10, 110 ) is further provided with one or several cooling agent feeder units ( 20, 36 ) for feeding cooling agents to the compressing unit ( 14 ) and with one or several cooling agent discharge units ( 24, 38 ) for discharging cooling agents from the compressing unit ( 14 ). At least one segment of the one cooling agent feeder unit or at least one segment of at least one, in particular each one of the several cooling agent feeder units ( 20, 36 ), is arranged thermally separated from the one cooling agent discharge unit or at least one, in particular each one of the several cooling agent discharge units ( 24, 38 ).
