A compressor system that includes a compressor, a refrigeration system, a
drive member and a cooling passage. The compressor is operable to produce
a flow of compressed fluid. The refrigeration system includes an
evaporator, and a flow of refrigerant passes through the evaporator and
is operable to cool the flow of compressed fluid. The drive member is
coupled to the compressor and is operable to drive the compressor. The
cooling passage extends from a point downstream of the evaporator to a
point upstream of the compressor. At least a portion of the cooling
passage is in thermal exchange relationship with the drive member.
