Abstract

L'invention concerne une pompe d'alimentation (1) muni d'une soupape d'entrée (12) pour commander l'aspiration d'un carburant dans une chambre de mise sous pression (3a) ainsi que d'une soupape de sortie (13) pour commander la distribution sous pression du carburant à partir de la chambre de mise sous pression (3a). La soupape d'entrée (12) et la soupape de sortie (13) sont disposées coaxialement dans un carter de soupape (14) et guidées par un corps de soupape commun (21). Un siège de soupape (22) de la soupape d'entrée (12) est construit sous la forme d'un corps séparé du corps de soupape (21).
