Abstract

Dispositif de réglage de la quantité de gaz d'échappement recyclés sur un moteur à explosion comprenant un conduit de liaison entre la tubulure d'échappement et la tubulure d'admission et un obturateur monté dans ledit conduit de liaison, caractérisé en ce que les portions du conduit de liaison situées entre l'obturateur 1 et la tubulure d'échappement 2 d'une part et la tubulure d'admission 4 et l'obturateur 1 d'autre part sont courtes et de forte section, la section de passage de l'obturateur 1, constituée par un cylindral 14 forme dans un siège 7, est réduite par rapport à la section dudit conduit de liaison et un clapet 6, cooperant avec le siège 7, comporte une extrémité cylindrique 12 de diamètre très légèrement inférieur et de longueur supérieure à ceux du cylindre 14 du siège 7.
