ABSTRACT:
The crest of a projecting helical thread formed on a rotor is located on a surface of revolution with respect to the rotor axis and cooperates in a fluid-tight manner with a stationary casing which surrounds the rotor. At least one toothed sealing wheel is engaged with the rotor thread so as to rotate about a transverse axis with respect to the rotor axis and one face of each tooth which is in mesh with the thread is exposed to the high-pressure fluid. The portions of each tooth-flank which are adjacent to said face are portions of surface of revolution and include those zones of the flanks which come into contact with the thread during rotational motion.
