Abstract

L'invention concerne un dispositif de recyclage de gaz d'échappement. Il comporte une tubulure prévue entre l'échappement et l'admission du moteur apte à acheminer une partie des gaz d'échappement vers ladite admission et est caractérisé par le fait qu'il comporte en outre d'une part une première et une deuxieme soupapes de contrôle de débit disposées sur ladite tubulure et en parallèle l'une par rapport à l'autre et d'autre part une troisième soupape de contrôle actionnée mécaniquement et disposée sur ladite tubulure en série avec lesdites première et deuxième soupapes, lesdites première et deuxième soupapes étant aptes à être actionnées par deux valeurs de dépression régnant dans l'admission d'un carburateur, et présentant des caractéristiques différentes entre elles, ladite troisième soupape étant actionnée par le papillon dudit carburateur. L'invention est mise en oeuvre dans les automobiles.
