Abstract

L'invention concerne une pompe à liquide. La pompe comporte un circuit de balayage et de refroidissement pour chaque ensemble de joints d'étanchéité 54 54a de son arbre 20. Chaque circuit comprend une cavité fermée 32 32a qui est formée dans le corps 12 de la pompe et comporte des orifices d'entrée 64 64a et de sortie 66 66a reliant la cavité à l'intérieur 14 du corps de pompe. Chaque ensemble de joints logé dans une cavite comprend un joint fixe et un joint annulaire rotatif formant pompe qui aspire le liquide par l'orifice d'entrée et le refoule par l'orifice de sortie après qu'il air balayé les joints. Les deux extrémités de la pompe sont munies d'un tel circuit, ces deux circuits étant reliés par un conduit 48 d'équilibrage des pressions. L'invention permet de réaliser le circuit de balayage et de refroidissement intégralement contenu à l'intérieur de la pompe.
