Abstract

La présente invention concerne un injecteur de carburant servant à injecter du carburant dans la chambre de combustion d'un moteur à combustion interne, et comprenant un corps d'injecteur (2, 16) dans lequel est disposé un pointeau (5, 30, 40) de manière à pouvoir se déplacer. L'extrémité (12) du pointeau (5, 30, 40) referme ou ouvre une ouverture d'injection (15) débouchant sur la chambre de combustion. Le pointeau (5, 30, 40) comprend au moins une section de guidage (6, 7, 45). A la section de guidage (7, 45) du pointeau (5, 30, 40), située côté corps d'injecteur, est associée une zone de restriction (17).
