Abstract

L'invention porte sur une pompe à haute pression (1) qui est équipée d'un plongeur (13) qui se déplace en mouvement alternatif, d'une chambre de mise sous pression (121) dans laquelle le carburant est mis sous pression par le plongeur (13), d'une chambre à carburant (16) qui renferme un amortisseur de pulsation (50) et à travers laquelle le carburant circule, et d'un carter (11) qui renferme la chambre à carburant. La chambre à carburant (16) est reliée à un passage de retour (310) par lequel le carburant est renvoyé de la chambre à carburant (16) à un réservoir de carburant (301). De plus, un passage de liaison (68) qui comprend un étranglement (69) relie la chambre à carburant (16) au passage de retour (310).
