Abstract
L'aiguille 3 de l'injecteur est appliquée contre un piston 15 qui coopère avec une douille 6 pour délimiter une chambre de refoulement 17. Le déplacement du piston (soulèvement de l'aiguille) et l'abaissement de la douille (pression d'un agent hydraulique sur la surface frontale 5 de la douille) occultent des lumieres 18. La chambre de refoulement fermée, bloque la course de l'aiguille. Les fonctions charge de l'aiguille et limitation de course sont ainsi séparées.
