ABSTRACT:
The threads of the gate rotor of a screw rotor machine are generated by a rounded crest portion of the main rotor thread so that the flanks of the gate rotor threads will have a contour tangent to a plurality of circles which have progressively decreasing diameters taken from the radially innermost to the radially outermost of said circles, with the circles each having a center which lies on a curved radial line directed forwardly of the direction of rotation of the gate rotor when the machine is operated as a compressor. A crest portion of the gate rotor threads shaped in conformity with the radially outermost of said contour-defining plurality of circles has its center lying within and closely adjacent to the pitch circle of the gate rotor, with the gate rotor thread crest portion projecting beyond the gate rotor pitch circle a distance corresponding approximately to the radius of the radially outermost circle.
