Abstract:
A compressor for refrigerant, comprising:a housing; a scroll compressor, which is disposed in the housing and has a first compressor body, which is disposed in a stationary position in the housing, and a second compressor body, which can move relative to the first compressor body, each of these bodies having a base and respective first and second scroll ribs, which rise above the respective base and engage in one another in such a way that, during compression of the refrigerant, the second compressor body can be moved along an orbital path about a center axis with respect to the first compressor body, a drive for the second compressor body, having a drive motor, a rear-side cooling chamber, arranged between the rear side of the first compressor body and a partition of the housing which is spaced from the rear side, and at least one aperture in the base of the first compressor body enabling refrigerant which is to be sucked into an intake region of the scroll compressor to flow at least in part through the rear side cooling chamber and then flow from the rear side cooling chamber through the at least one aperture in the base of the first compressor body in order to cool the first compressor body in the region of the rear side, the second compressor body being adapted to enable the refrigerant which is to be compressed by the scroll compressor to wash around the second compressor body, so that the second compressor body can be cooled.
