Abstract

L'invention concerne un dispositif (100) comportant une ligne d'admission (55) d'air vers un moteur à combustion de véhicule automobile, cette ligne d'admission étant disposée en amont d'un circuit de recirculation de gaz d'échappement (50), la ligne d'admission étant reliée à ce circuit, cette ligne d'admission comportant une vanne (2) agencée pour générer une perte de charge de l'air d'admission circulant dans cette ligne, cette vanne étant agencée pour pouvoir occuper seulement deux positions stables de fonctionnement.
