Abstract

La présente invention concerne un système d'alimentation en carburant haute pression réduisant le bruit créé à l'ouverture et la fermeture d'une électro-vanne. L'électrovanne (100) du système comporte un corps (41), un plongeur (40) coulissant dans le corps (41), un siège de soupape (42) avec lequel une extrémité du plongeur est amenée à venir en contact et hors de contact en mettant le siège de soupape en communication avec une chambre de mise sous pression de carburant (27) lorsqu'il s'écarte du siège de soupape, une butée (43) pour limiter la distance séparant le plongeur du siège de soupape et un ressort (48) pour repousser le plongeur en direction du siège de soupape. Un joint torique élastique (101) est agencé autour du siège de soupape pour absorber les bruits de collision produits lorsque le plongeur vient heurter le siège de soupape.
