Abstract

L'invention concerne les pompes à engrenage. La pompe de l'invention comprend un corps 10 définissant un alésage 14 fermé par des parois d'extrémité 13 et 15. Deux étages de pompage 31 et 31, consistant chacun en une pompe à engrenages sont montés dans l'alésage 14 entre les élements de stator 20, 21 et 23. Le premier étage de pompage a un débit supérieur à celui du second et l'excédent de fluide s'écoule par un clapet 42. Application aux pompes de carburant pour les moteurs Diesel.
