Abstract (en)
[origin: WO2015086159A1] The invention relates to a screw compressor (10) with at least one screw rotor (20, 22) which is rotatably arranged about a rotational axis arranged in the axial direction. The at least one screw rotor (20, 22) is arranged in a compression area (24) which is fluid-tight against the surrounding area at least in some sections and opens into a high-pressure volume (26). The compressor (10) further has a Vi slide (28) for influencing an inner volume ratio of the compressor, said Vi slide (28) at least partly forming a section of the fluid-tight border of the compression area (24) and being arranged such that the position of the slide can be adjusted in the axial direction. The Vi slide (28) can be continuously displaced, and the compressor (10) has a device (32) for detecting the position of the slide.
