摘要： A scroll-type compressor for a CO2 vehicle air conditioning system, having a movable displacement spiral which is rotatably connected to an eccentric bearing and which engages into a counterpart spiral such that, between the windings of the displacement spiral and of the counterpart spiral, there are formed chambers which travel radially inward in order to compress the refrigerant and discharge the refrigerant into a pressure chamber, wherein the displacement spiral is arranged on the suction side and the counterpart spiral is arranged on the high-pressure side. The scroll-type compressor is wherein the eccentric bearing is arranged in the displacement chamber between the displacement spiral and the counterpart spiral and has a bearing bushing which is formed integrally with the displacement spiral and the base of which is in alignment with the face side of the windings of the displacement spiral.

摘要： A scroll-type compressor for a CO2 vehicle air conditioning system, having a mechanical drive which is connected by a drive shaft to an eccentric bearing. A movable displacement spiral is rotatably connected to the eccentric bearing and engages into a counterpart spiral such that, between the displacement spiral and the counterpart spiral, radially inwardly traveling chambers are formed in order to compress the refrigerant and discharge it into a pressure chamber. Wherein the counterpart spiral is movable in alternating fashion relative to the displacement spiral in an axial direction, wherein, between the counterpart spiral and the displacement spiral, there is arranged at least one spring for exerting an axial release force on the counterpart spiral, and at least one piston engages on the counterpart spiral, in order to exert an axial closing force on the latter, adjacent to the pressure chamber in an off-center position.
