Abstract

L'invention concerne un injecteur pour moteurs à combustion interne, comportant un boîtier (1) et une soupape de commande permettant de connecter une chambre de commande (15) à une chambre de trop-plein d'huile (40). La soupape de commande (5) comporte un corps de soupape (25) et un manchon de commande (32) pouvant être déplacé par un électro-aimant (37), le manchon de commande (32) délimitant, radialement vers l'extérieur, une chambre annulaire (30) connectée à la chambre de commande (15). Le manchon de commande (32) agit avec un siège de soupape (42) formé sur le corps de soupape (25) pour ouvrir et fermer une section transversale connectant la chambre annulaire (30) à la chambre de trop-plein d'huile (40). Le manchon de commande (32) présente une section cylindrique extérieure (49) qui fait face à une section cylindrique intérieure (48) sur le corps de soupape (25) lorsque le manchon de commande (32) s'appuie sur le siège de soupape (42), de telle manière qu'un espace d'étranglement (50) est formé entre la section cylindrique extérieure (49) du manchon de commande (32) et la section cylindrique intérieure (48) du corps de soupape (25).
