ABSTRACT:
A compressor for an air-conditioning system of a motor vehicle is proposed, which has a controllable compression medium feed mechanism powered by a drive shaft and which, for example, is powered by the combustion engine of the motor vehicle by a belt driven by a drive shaft, where the belt is coupled with the drive shaft of the compressor. the compressor is characterized by the drive wheel (29) having a belt pully body (31) engaged with the belt (33) and coupled via an elastic coupling element (35) with the drive shaft (7), and by the drive shaft (7) being equipped with a torque limiting mechanism (predetermined fracture point (65)). In the case of another version, it is envisaged that the support mechanism (127) contains a projection (137) protruding from the take-up plate (11) and preferentially forming a single piece with this, as well as a supporting element (139). Furthermore, it is envisaged that the supporting element (139) has a first sliding surface (143) which works in conjunction with a bearing surface (second bearing surface (145)) of the thrust bearing (129), and that the projection (137) and the supporting element (139) fit tightly together via a second sliding surface (147) and/or that the driver (81) and the drive shaft (7) are joined using different materials or are made from a single piece.
