Abstract

L'invention porte sur un dispositif d'alimentation en carburant compact et à faible coût. Dans un dispositif d'alimentation en carburant (1) agencé pour distribuer du carburant (F) à partir d'un réservoir de carburant (2) tout en mettant sous pression le carburant au moyen d'une pompe d'alimentation (3), la pompe d'alimentation (3) comporte de plus un dispositif de soupape (30) ayant un corps principal cylindrique (31) équipé d'un premier orifice (30A) relié à un orifice côté sortie de carburant (3B) et des second et troisième orifices (30B, 30C) reliés à un orifice côté entrée de carburant (3A). Une régulation de pression de l'orifice côté sortie de carburant (3B) est effectuée par ouverture/fermeture du second orifice (30B) selon la pression du carburant du premier orifice (30A) au moyen d'un élément de soupape de piston (32) et d'un élément de ressort (33) disposé dans le corps principal cylindrique (31). Lorsque la pression de carburant du troisième orifice (30C) devient supérieure à celle du premier orifice (30A) au moyen d'un mécanisme de clapet anti-retour (34) disposé dans l'élément de soupape de piston (32), la pression de carburant du troisième orifice (30C) est relâchée vers le premier orifice (30A).
