Abstract

Pompe à carburant comportant une soupape de décharge. La pompe à carburant comporte une chambre de compression (10) dans laquelle le carburant est mis sous pression, et une soupape de décharge (2) ayant une entrée en communication avec une sortie haute-pression (13) pour libérer du carburant, la soupape de décharge (2) étant placée dans un logement (15) et comportant un obturateur (20) sollicité en appui par un ressort (21) contre un siège (220) porté par une bague de siège (22). La soupape de décharge (2) comporte une pièce de guidage (23) sur laquelle le ressort (21) prend appui à l’opposé de l’obturateur (20), la pièce de guidage (23) étant montée coulissante dans une bague d’arrêt (25) fixée dans le logement (15) et limitant le coulissement de la pièce de guidage (23) à l’encontre du ressort (21).
