Abstract
In order to improve a screw compressor for compressing a working medium, comprising an outer housing, two screw rotors which are arranged in the outer housing in rotor bores provided for them and a drive for the screw rotors, in such a manner that the sealing gap is subject to as little variation as possible it is suggested that a compressor screw housing, in which the rotor bores for the screw rotors are arranged, be provided within the outer housing and that a space be arranged between a substantial part of the compressor screw housing and the outer housing.
