Cover Story: Conical screw compressors use a mechanism consisting of two conically shaped rotors, which rotate one inside the other. This specific design offers advantages in terms of efficiency, durability and compactness. These compressors are characterized by high efficiency, durability, compact dimensions and silent operation. The screw profiles of conical screw compressors are mutually enveloping, with this aspect being essential for its correct operation. This paper proposes an algorithm for profiling the compressor stator, based on the method called "virtual contact point method", developed at the "Dunărea de Jos" University of Galați. The proposed method is based on the observation that the sealing of the compression chambers is done on a curve that follows the axial section of the two screws, in a plane determined by their axes. View this paper
