Abstract

Motopompe électrique à tube de séparation de la chambre du rotor. La longueur axiale de l'orifice d'équilibrage 12 faisant communiquer la chambre de pompage 10 avec la chambre du rotor 11, dans le sens de circulation d'équilibrage du liquide, est supérieure à la plus grande dimension transversale dudit orifice et le volume contenu dans ledit orifice est supérieur au volume du courant d'échange maximal entre les chambres respectives du rotor et de la pompe pouvant prendre naissance sous l'action des variations de température du liquide contenu dans l'une ou l'autre chambre ou de modifications de la pression dans le circuit.
