Abstract

Injecteur (1) pour système d'injection de carburant, comprenant un corps de buse (2) dans lequel est formé un compartiment sous pression (4) qui est apte à être rempli de carburant et dans lequel une aiguille d'injecteur (5) en forme de piston et présentant un axe longitudinal (11) est apte à coulisser longitudinalement et coopère avec le siège de buse (8) pour ouvrir et fermer au moins un orifice d'injection (10). L'aiguille d'injecteur (5) abrite un évidement (20; 20') en forme de fente, lequel comprend au moins une partie du volume de l'aiguille d'injecteur (5) à partir de la surface de l'aiguille d'injecteur (5), à travers lequel passe l'axe longitudinal (11).
