The invention relates to a compressor especially for an automobile air conditioning system, containing a compressor unit (2) for suction and compression of a cooling medium arranged inside of the housing (1). Said compressor unit (2) has a piston (7) which operates inside a cylinder block (6) and a driving plate (8), i.e. a swash or pivot plate, which actuates said piston (7). In order to increase efficiency, the invention is characterized in that the driving plate (8) is mounted in such a way that the center line (9) of mounting, i.e. swash or mounting axis, forms a tangential line to the reference circle (10) defined by the stroke so that the angle of inclination (11) of the driving plate (8) can be changed without displacing the dead center above the stroke position. The compressor providing increased efficiency is also characterized in that the driving plate is mounted in such a way that the center line of mounting, i.e. swash or mounting axis, forms a tangential line to the reference circle defined by the stroke so that the angle of inclination of the driving plate can be changed without displacing the dead center above the stroke. In order to increase efficiency, the compressor is constructed in such a way that the components which come in contact with the cooling medium, preferably the walls configured between the intake and outlet areas along the flow path, are slightly thermally shielded from the cooling medium in the area of the flow path. In addition, the compressor is constructed in such a way that the belt is protected by means of uncoupling of the coupling assembly when a defined thermal and/or mechanical capacity limit is exceeded during blocking of the drive shaft or compression unit. |
