<p>A compressor, in particular for the air conditioning system of an automobile, with a housing (1) and a compressor unit (2) accommodated in the housing (1) for taking in and compressing a refrigerant, wherein the compressor unit (2) comprises pistons (7) reciprocating in a cylinder block (6) and a drive disk-swash plate or pivot disk (8)-that drives the pistons (7), is characterized for increasing efficiency in that the drive disk (8) is supported such that a center line (9) of the bearing mount (pivoting or bearing axis) forms a tangent to a reference circle (10) defining the stroke, so that an angle of inclination (11) of the drive disk (8) is variable, without displacing the dead center above the stroke position. Furthermore, for increasing efficiency, the compressor is characterized in that the drive disk is supported such that the center line of the bearing mount (pivoting or bearing axis) forms a tangent to the reference circle defining the stroke, so that the angle of inclination of the drive disk is variable, without displacing the dead center above the stroke position. Furthermore, for increasing efficiency, the compressor is designed and constructed such that components coming into contact with the refrigerant, preferably the walls forming a flow path between an intake area and a discharge area are thermally insulated against the refrigerant at least in part and in areas of contact. Finally for an effective protection of the belt in the case of a blocking drive shaft or compressor unit, the compressor is designed and constructed such that a coupling device automatically disengages, when a defined thermal and/or mechanical load limited is exceeded.</p> |
