SCROLL-TYPE COMPRESSOR AND CO2 VEHICLE AIR CONDITIONING SYSTEM HAVING A SCROLL-TYPE COMPRESSOR

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.
