Abstract

Dispositif de recyclage (1) des gaz d'échappement pour un moteur à combustion interne, en particulier dans un véhicule à moteur, qui comporte une conduite (2) de recyclage des gaz d'échappement destinée à introduire des gaz d'échappement dans une conduite d'air frais (4), et une soupape (3) de recyclage des gaz d'échappement destinée à commander la conduite (2) de recyclage des gaz d'échappement, la conduite (2) de recyclage des gaz d'échappement comportant un segment terminal (7) s'étendant dans la conduite d'air frais (4) et pourvu d'un orifice de sortie (8). L'objet de la présente invention est d'améliorer la fiabilité dudit dispositif de recyclage (1) des gaz d'échappement. A cet effet, la soupape (3) de recyclage des gaz d'échappement possède un manchon (10) placé dans la conduite d'air frais (4), qui entoure la conduite de recyclage (2) des gaz d'échappement dans la zone de l'orifice de sortie (8), qui est installé de manière à pouvoir être déplacé axialement dans la conduite d'air frais (4) et qui possède radialement sur sa face interne un profil de buse (11) avec une section transversale d'écoulement se rétrécissant d'abord puis s'élargissant dans le sens d'écoulement, la soupape (3) de recyclage des gaz d'échappement possédant un dispositif de réglage (12) pour le déplacement axial du manchon (10) par rapport à la conduite d'air frais.
