Abstract
A compressor for an air conditioning system in an automobile, having a housing (1) and a compressor unit (2) accommodated in the housing (1) for taking in and compressing a refrigerant. The refrigerant flows from an intake area (4) preferably in a front-end housing cover (3) through the compressor unit (2) into a discharge area (5), preferably likewise designed and constructed in the housing cover (3). The compressor is designed and constructed for promoting efficiency such that components coming into contact with the refrigerant, particularly the walls forming a flow path (6) between the intake area (4) and the discharge area (5) are thermally insulated against the refrigerant at least partially and in areas of contact. For an effective protection of the drive belt when the drive shaft or the compressor unit locks, the compressor is further designed and constructed such that a coupling device automatically disengages, when a defined thermal and/or mechanical load limit is exceeded.
