Abstract

L'invention concerne un obturateur s'adaptant à tout pot d'échappement et interdisant à l'air de rentrer à l'intérieur et de refouler les impuretés restant dans le pot d'échappement grâce au fonctionnement d'une soupape 4; il est constitué d'un corps 1, d'un amortisseur cylindrique 2 et d'un ressort de rappel 3. Le dispositif selon l'invention est particulièrement destiné aux pots d'échappement; la température élevée dégagée par le moteur, l'entrée d'air venant de l'extérieur dégradent ces derniers, l'obturateur a pour effet d'arrêter cette dégradation et de prolonger la durée d'utilisation du pot.The invention relates to a shutter adapting to any muffler and preventing the air from entering the interior and discharging the impurities remaining in the muffler thanks to the operation of a valve 4; it consists of a body 1, a cylindrical damper 2 and a return spring 3. The device according to the invention is particularly intended for exhaust pipes; the high temperature given off by the motor, the air intake coming from the outside degrade the latter, the shutter has the effect of stopping this degradation and of prolonging the life of the pot.
