Abstract

L'invention concerne une soupape d'injection de carburant (1), notamment une soupape d'injection pour systèmes d'injection de carburant de moteurs à combustion interne. Cette soupape d'injection comprend une bobine d'excitation (2), un induit (7) sollicité en position de fermeture par un premier ressort de rappel (8) et un pointeau de soupape (10) communiquant par liaison de force avec l'induit (7) pour actionner un corps de fermeture de soupape (11) qui forme un siège d'étanchéité conjointement avec une surface de siège de soupape (12). La soupape d'injection de carburant (1) peut être placée dans une première position de commutation avec une première section transversale d'ouverture, en faisant circuler dans la bobine d'excitation (2) un courant de maintien d'une première intensité et dans une seconde position de commutation avec une seconde section transversale d'ouverture, en faisant circuler dans la bobine d'excitation (2) un courant de maintien d'une seconde intensité.
