Abstract

L'invention a pour objet une vanne de régulation de gaz d'échappement destinée à être agencée au moins en partie dans un dispositif d'interface (40) entre un système de dépollution (30) de gaz d'échappement et un conduit d'échappement (24), le dispositif d'interface comprenant : - une entrée (44) agencée pour recevoir le gaz d'échappement sortant du système de dépollution (30), - une sortie d'échappement (46) agencée pour faire entrer le gaz d'échappement dans le conduit d'échappement (24), et - une sortie auxiliaire (48) pour le gaz d'échappement; la vanne comprenant : - un corps (60) délimitant un conduit interne (62) comportant une extrémité destinée à être raccordée à la sortie auxiliaire (48) du dispositif d'interface (40), et - un volet (70) comportant une première aile (72) et une seconde aile (74), le volet (70) étant monté mobile entre une position d'ouverture permettant le passage du gaz d'échappement dans le conduit interne (62) et une position de fermeture empêchant ledit passage par la première aile (72), et pour que, lorsque le volet (70) est en position d'ouverture, la seconde aile (74) obture partiellement la sortie d'échappement (46) du dispositif d'interface (40).
