Abstract

L'invention concerne une électrovanne (2) permettant de piloter une soupape d'injection (1) de moteur à combustion interne, qui comprend un électroaimant (34), un induit (29) mobile, un élément de soupape de commande (25, 26) coopérant avec un siège de soupape (24) pour ouvrir et fermer un canal de décharge de carburant (17) de chambre de pression de commande (14) de la soupape d'injection et une pièce coulissante (40) guidant l'induit (29), qui est montée conjointement avec l'induit (29) et l'élément de soupape de commande (25, 26) dans une chambre d'induit (51, 52). Afin de réduire le rebondissement de l'induit, il est prévu que la pièce coulissante (40) divise la chambre d'induit en une chambre de détente (52) reliée à un raccordement basse pression de carburant (10) et en une chambre de vaporisation (51) hydraulique dans laquelle débouche le canal de décharge de carburant (17). Ladite chambre de vaporisation peut être détendue par l'intermédiaire d'au moins un canal de jonction (44, 47) menant vers la chambre de détente (52) et muni d'un papillon d'étranglement (43, 48). La vitesse de l'élément de la soupape de commande (25, 26) est réduite lors de la fermeture de l'électrovanne (2) avant la butée sur le siège de soupape (25, 26) par un coussin de pression de carburant agissant dans la chambre de vaporisation (51) sur l'élément de soupape de commande (25, 26).
