Abstract: front page image
(EN)The fuel (C) injector (10) according to the invention comprises a tubular body (12) provided with a bore (14) and a needle (18) that is arranged axially (A) sliding in the bore (14), the needle (18) having a cross-section significantly smaller than that of the bore (14). The needle (18) is locally provided with a collar (20) extending radially from the needle (18) to the vicinity of the wall (16) of the bore (14) and longitudinally (A) between an upstream face (22) and a downstream face (24). The collar (20) is provided, in its longitudinal peripheral wall (26), with at least one groove (28) so as to create at least two restrictions (R1, R2) that the fuel (C) must cross in series.
(FR)Un injecteur (10) de carburant (C) comprend un corps (12) tubulaire pourvu d'un alésage (14) et, une aiguille (18) agencée axialement (A) coulissante dans l'alésage (14), l'aiguille (18) ayant une section transversale nettement inférieur à celle de l'alésage (14). L'aiguille (18) est localement pourvue d'une collerette (20) s'étendant radialement depuis l'aiguille (18) jusqu'à proximité de la paroi (16) de l'alésage (14) et longitudinalement (A) entre une face amont (22) et une face avale (24). La collerette (20) est pourvue dans sa paroi périphérique (26) longitudinale d'au moins une gorge (28) de sorte à créer au moins deux restrictions (RI, R2) que le carburant (C) doit franchir en série.
