Abstract

L'invention a pour objet une pompe à injection de carburant liquide comprenant un plongeur de pompage amené d'un mouvement alternatif dans un cylindre et se prolongeant au-delà d'une extrémité du cylindre, des moyens provoquant le mouvement alternatif du plongeur, un orifice de sortie à l'autre extrémité du cylindre, et au moins un orifice formé dans la paroi du cylindre, ledit orifice communiquant avec une conduite d'alimentation en carburant Selon l'invention, la pompe à injection comprend des moyens qui font communiquer la chambre de pompage avec ledit orifice formé dans la paroi du cylindre pendant une partie de la durée pendant laquelle le plongeur participe à la course de pompage, lesdits moyens agissant pour faire passer du carburant de la chambre de pompage dans ledit orifice et entraîner ainsi toute cavité pouvant s'y trouver, vers ladite conduite d'alimentation.
