Abstract
A compressor, which is adapted for use in an air-conditioning system of a motor vehicle, having a housing (2) and a compressor unit (1) arranged in the housing (2) for drawing in and compressing a coolant. The structural size of the compressor is reduced, while sufficient compressor capacity is ensured, as a result of manufacturing the housing (2) from a high-strength material and using a gas that has a high density even in the drawn-in state as the coolant.
