Abstract

L'invention concerne une soupape d'injection de carburant (1) pour des installations d'injection de carburant de moteurs à combustion interne, comprenant une bobine d'électro-aimant (10), une tige de soupape (3) en liaison active avec la bobine d'électro-aimant (10) et soumise à l'action d'un ressort de rappel (23) dans un sens de fermeture pour actionner un élément de fermeture de soupape (4), qui forme un siège d'étanchéité avec une surface (6) de siège de soupape façonnée sur un élément (5) de siège de soupape. Ladite soupape comporte également, en aval de l'élément (5) du siège de soupape, un disque à orifices d'injection (36) qui, dans le sens du flux du carburant, forme une calotte incurvée.
