Abstract

L'invention concerne un dispositif d'injection (1) comportant une rampe commune (2) s'étendant dans une direction longitudinale et définissant un chambre principale (4), la rampe commune (2) comportant : - un orifice d'entrée (3), - au moins un puits d'injection (5), - au moins un conduit (6) débouchant dans la chambre principale (4) et dans le puits d'injection (5) ; et - au moins un perçage (7) traversant, débouchant dans la chambre principale (4) en regard du conduit (6), le dispositif d'injection comportant en outre au moins un organe d'obstruction (8) qui comporte une première partie (8a) logée dans le perçage (7) et obturant de manière étanche ledit perçage (7) et une deuxième partie (8b) qui est logée dans le conduit (6) de manière à réduire la section de passage du carburant au travers dudit conduit (6) de sorte à former un gicleur.The invention relates to an injection device (1) comprising a common rail (2) extending in a longitudinal direction and defining a main chamber (4), the common rail (2) comprising: - an inlet port ( 3), - at least one injection well (5), - at least one conduit (6) opening into the main chamber (4) and into the injection well (5); and - at least one through hole (7), opening into the main chamber (4) facing the duct (6), the injection device further comprising at least one obstruction member (8) which comprises a first part (8a) housed in the bore (7) and sealingly closing said bore (7) and a second part (8b) which is housed in the duct (6) so as to reduce the section of passage of the fuel through said duct (6) so as to form a nozzle.
