摘要
An improved screw compressor for the compression and axial displacement of a gas is set forth. The compressor is of the type having a housing formed with an axially extending passage. The axially extending passage has at one axial end thereof a gas inlet and at the other axial end thereof a gas outlet. A one piece male rotor is positioned in the passage and extends axially therein. The male rotor is formed with a plurality of helical ribs having generally convex flanks and root regions which are at least partially formed as involutes in cross section. Each rib of the male rotor has a profile consisting of a leading flank formed at least partially as an involute generated from a first base circle and a trailing flank at least partially formed as an involute generated from a second base circle. The second base circle has a diameter greater than the first base circle.
