Abstract

L'invention a pour objet un débitmètre volumétrique comportant deux rotors en prise l'un avec l'autre. Elle est caractérisée en ce que les rotors comportent des dents munies dans leur partie de têtes de profils en cycloïde et dans leur partie de pieds de profils en trochoïde, le profil des dents d'un rotor étant identique à celui des dents de l'autre rotor, ce qui permet une transmission uniforme d'énergie entre les deux rotors, et par conséquent une élimination de l'usure des dents des deux rotors. Elle se rapporte au domaine des débitmètres.
