摘要： In order for 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, and a drive for the second compressor body, having a drive motor, to be improved with regard to its performance, that the refrigerant which is to be compressed by the scroll compressor can wash around the two compressor bodies in the region of their rear side, which is remote from the scroll ribs, so that the compressor bodies can be cooled, it is proposed that the refrigerant which is to be compressed by the scroll compressor can wash around the two compressor bodies in the region of their rear side, which is remote from the scroll ribs, so that the compressor bodies can be cooled.

摘要： To provide a screw compressor comprising a compressor screw housing, two screw rotors with intermeshing screw bodies arranged in the compressor screw housing and with shaft sections arranged on both sides of the screw bodies, the screw rotors being mounted by means of the shaft sections in bearing housings arranged on both sides of the compressor screw housing, which prevents pressure losses, it is proposed that an intermediate portion of the respective shaft section adjoining an end of the respective screw body at the pressure side and extending as far as a bearing section be sealed off in the area of a closure wall of the compressor screw housing at the outlet side from an inside surface of an opening in the closure wall, which surrounds the intermediate portion.
