Abstract
A compressor having a purge circuit. In one embodiment, the compressor includes: a rotor having a plurality of stages, each of the plurality of stages including a set of radially extending rotor wheels; a working fluid supply path for providing working fluid to each of the plurality of stages for compression by each set of radially extending rotor wheels; a purge circuit for diverting a first portion of the working fluid from an upstream portion of the working fluid supply path to at least one downstream stage of the plurality of stages; and a substantially axial bypass path bypassing the at least one downstream stage, the substantially axial bypass path for diverting a second portion of the working fluid around the at least one downstream stage.
