Abstract

L'invention concerne une soupape d'injection de carburant (1), équipant notamment les systèmes d'injection de carburant des moteurs à combustion interne. Cette soupape comporte une première tige (3) en liaison active avec un premier élément de fermeture de soupape (4). Ce premier élément de fermeture de soupape (4) coopère avec une première surface de siège de soupape (5) dans un corps de siège de soupape (6) pour former un siège d'étanchéité (7). La soupape d'injection de carburant (1) comprend au moins un orifice d'injection (8) disposé en aval du siège d'étanchéité (7). En amont de ce siège d'étanchéité (7), un élément de turbulence (28) est situé dans l'alimentation du carburant, cet élément étant pourvu d'au moins un canal de turbulence (34) et d'au moins un canal de distribution à turbulence (30) qui débouchent dans une chambre de turbulence (35). Une deuxième tige de soupape (20) peut recouvrir des orifices d'alimentation de commande (29) ouvrant sur les canaux de distribution à turbulence (30).
