Abstract (en)
[origin: WO2010012570A2] To improve a screw-type compressor comprising an outer housing, a compressor screw housing which is arranged in the outer housing and in which are arranged rotor bores for screw rotors, a drive which is arranged in the outer housing on one side of the compressor screw housing, a bearing housing which is arranged in the outer housing on an opposite side of the compressor screw housing from the drive, and a silencer which is arranged within the outer housing and through which compressed working medium flows, in such a way that the working medium exiting the screw-type compressor entrains as little lubricant as possible, it is proposed that, in an interior space, the silencer conducts the compressed working medium by means of a flow guide as a rotating flow about an axis, and that lubricant is separated from the encircling flow of the working medium by centrifugal forces.
