Abstract

L'invention concerne une machine rotative à vis, telle qu'un compresseur à vis, une pompe à vide ou un moteur, comprenant des rotors homologues présentant des profils asymétriques et le même diamètre extérieur. De préférence, l'extrémité de la dent de rotor mâle présente, du point de vue du rayon maximum, sur les deux flancs, deux parties d'arc d'un cercle de dimension sensiblement différentes en ce qui concerne le rayon mais tangentes, décrivant une partie du flanc gauche et une partie du flanc droit respectivement. Le rotor femelle présente les éléments homologues respectifs dans la zone correspondante du fond de la dent. De préférence, le rotor mâle présente trois ou quatre filets, tandis que le rotor femelle présente de préférence six ou sept filets, et idéalement le rotor mâle présente quatre filets et le rotor femelle présente sept filets. Des lignes peuvent être tracées du centre du rotor femelle de manière tangente aux deux flancs de la même dent.
