Abstract

La présente invention permet d'abaisser les exigences en ce qui concerne les techniques de fabrication de rotors (3, 4) et la propreté du milieu de travail, d'accroître le niveau d'étanchéité des chambres de travail (8), de simplifier l'assemblage et la réparation du fait que le rotor externe (3) est composite et se compose de pièces interchangeables, d'améliorer l'efficacité de fonctionnement du moteur du fait de l'accroissement du volume de travail relatif des chambres des rotors, de la modification de la caractéristique de frottement aux points de contact des rotors (passage d'un frottement par glissement à un frottement par roulement) et de l'accroissement de surface de la plage de contact.
