Abstract

L'invention concerne des pompes du type gérotor comprenant des anneaux dansants contraints latéralement (22), ce qui permet d'obtenir un degré de liberté orthogonal et permet aux ensembles de type gérotor (12) positionnés dans lesdites pompes de déterminer leur propre orientation d'engrènement préférée. Par ailleurs, le rotor extérieur de l'ensemble de type gérotor est positionné de force contre le rotor intérieur de l'ensemble de type gérotor dans la position d'engrènement de ce dernier, le mouvement relatif entre les rotors intérieur (14) et extérieur étant ainsi faible. On obtient ainsi un effet d'engrènement sensiblement sans usure et sans frottement de l'ensemble du type gérotor.
