Abstract

Injecteur de carburant pour moteur à combustion interne prévu pour déclencher et doser avec précision une injection de fluide ayant un débit prédéterminé variant au cours du temps, caractérisé en ce qu'il comprend en combinaison une chambre de pression destinée à recevoir ledit débit, une valve d'injection communiquant avec ladite chambre de pression et susceptible de s'ouvrir en réponse à un niveau de pression régnant dans ladite chambre pour délivrer une injection de carburant dans une chambre de combustion dudit moteur, et des moyens destitués à absorber une quantité de carburant, lesdits moyens communiquant avec ladite chambre de pression et étant adaptés à absorber un débit de carburant variant avec le temps et provenant de la chambre de pression de façon à faire varier ledit débit à travers ladite valve d'injection au cours du temps. Application aux moteurs à combustion interne.
