Carbon dioxide axial piston compressor for vehicle air conditioning system, has further separator near cylinder block in bypass line leading from drive mechanism chamber to suction side of compressor

摘要

The device has a housing (27) bounding a drive mechanism chamber (21), a cylinder block (22) and a cylinder head (23). The high pressure side (25) of the compressor (20) has an associated lubricant or oil separator. A further separator (28) active between the drive mechanism chamber and compressor suction side (26) is arranged near the cylinder block in a bypass line (29) from the drive mechanism chamber to the suction side of the compressor.
