Title (EN) MUFFLER FOR MOTOR VEHICLES
(FR) SILENCIEUX POUR VÉHICULES À MOTEUR
Abstract: front page image
(EN)A muffler (4) for motor vehicles comprising an intake pipe (8) of the exhaust gases that separates, at a fork (10), into a main pipe (12) and a secondary pipe (16), a muffler body (24) which delimits an expansion volume (28) and houses at least partly the main pipe (12) and the secondary pipe (16), wherein the intake pipe (8) of the exhaust gas is in fluid continuous connection with the main pipe (12) through the secondary pipe (16), and wherein the main pipe (12) comprises, downstream of the fork (10), a throttle valve (32) which allows or prevents a further fluidic connection of the intake pipe (8) of exhaust gas with the main pipe (12), and an output of the exhaust gases (40), for the expulsion of the gases from the muffler pipe (4).
(FR)L'invention concerne un silencieux (4) pour véhicules à moteur. Ce silencieux comprend un tuyau d'admission (8) de gaz d'échappement qui se sépare, au niveau d'une fourchette (10), en un tuyau principal (12) et un tuyau secondaire (16), un corps de silencieux (24) qui délimite un volume d'expansion (28) et loge au moins partiellement le tuyau principal (12) et le tuyau secondaire (16), le tuyau d'admission (8) du gaz d'échappement étant en liaison continue fluidique avec le tuyau principal (12) à travers le tuyau secondaire (16), et le tuyau principal (12) comprenant, en aval de la fourchette (10), un papillon des gaz (32) qui permet ou empêche une autre connexion fluidique du tuyau d'admission (8) de gaz d'échappement avec le tuyau principal (12), et une sortie de gaz d'échappement (40), pour l'expulsion des gaz du tuyau de silencieux (4).
