Abstract

L'invention concerne une pompe volumétrique (13) comprenant un corps (15) définissant une chambre (16) et un côté d'entraînement (18), un rotor (12) qui transfère un fluide depuis au moins un premier environnement vers au moins un second environnement par au moins un orifice d'entrée d'un conduit d'aspiration (19) et au moins un orifice de sortie d'un conduit d'évacuation, une roue d'engrenage entraînée (10a, 11) jointe de manière fixe audit rotor (12) et une roue d'engrenage d'entraînement (10a, 11) joignable à l'élément d'entraînement (10) et couplée à ladite roue entraînée (10a, 11), ladite roue entraînée étant conçue pour tourner autour dudit rotor (12). La roue d'entraînement (10a, 11) et la roue entraînée (10a, 11) sont situées l'une dans l'autre de manière à obtenir une réduction ou une multiplication d'un rapport de vitesse. L'invention concerne également un procédé de fonctionnement de ladite pompe.
