Abstract

L'invention concerne une pompe centrifuge dont le rotor 14, alimenté en liquide ou en mélange de gaz et de liquide par sa partie centrale 18, comporte une pluralité d'aubes radiales 22 définissant entre elles des passages de fluide rectilignes ou incurvés 24 dont les extrémités 26 sont rétrécies pour former des buses de décharge dans le collecteur spiral 20 du carter de pompe, les rapports dimensionnels des deux parties de chaque passage étant établis de façon à permettre à la pompe de donner un écoulement et une pression stables sans produire de vibrations mécaniques préjudiciables quel que soit le rapport gaz-liquide du mélange déplacé. La pompe convient particulièrement aux circuits de carburant des aéronefs.
