Abstract
L'invention concerne un appareil de pompage pour l'injection de combustible dans un moteur à combustion interne, comprenant des pompes d'injection et d'alimentation, un organe mobile axialement, un orifice réglable défini par une rainure dans l'organe et une lumière dans le corps, une masselotte centrifuge pivotante, un ressort de régulateur pour rappeler l'organe contre l'action de la masselotte, un organe de réaction pour le pivot de la masselotte, et un amortisseur pour limiter la vitesse de déplacement de l'organe de réaction. L'appareil est caractérisé par le fait qu'il est formé une deuxième rainure dans l'organe mobile, espacée de la première rainure, déplacée en face de ladite lumière lorsque ledit orifice est fermé pendant le ralentissement du moteur, et communiquant de façon réduite avec la première rainure, de manière qu'une faible quantité de combustible puisse être envoyée dans le moteur lorsque ledit orifice est fermé, pendant le ralentissement du moteur.
