Abstract

L'invention concerne un système de recyclage des gaz d'échappement, servant à réintroduire les gaz d'échappement dans l'arrivée des gaz de moteurs, notamment de moteurs automobiles. Ce système comprend une arrivée de gaz d'échappement (5), une arrivée de gaz frais (2) et un canal de sortie (4) débouchant dans l'arrivée de gaz d'échappement (5). Au moins l'arrivée de gaz d'échappement (5) et l'arrivée de gaz frais (2) sont reliées par l'intermédiaire d'un organe de commande (69) servant à doser les gaz d'échappement. Une plaque de pression (44) placée du côté de l'organe de commande (69), opposé à l'arrivée de gaz frais (2), minimise l'influence des variations de pression apparaissant côté gaz d'échappement et côté gaz frais et agissant sur le débit des gaz d'échappement.
