Abstract: A linear compressor assembly includes a housing having a bore formed therein, the bore being axially oriented along a first axis, a piston reciprocally disposed within the bore, and a plurality of drive coils adjacent the bore for energizing the drive coils to produce a magnetic field capable of displacing the piston within the bore substantially along the first axis. A controller is used for selectively controlling energizing of the drive coils. A cooling system is at least partially disposed in the housing and the cooling system is used for cooling the apparatus.

Abstract: 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.
