Abstract

Dispositivo reductor de los ruidos radiados por el tubo de escape de un motor térmico, provisto de un silenciador de amortiguamiento de los ruidos de escape, caracterizado por el hecho de comprender, curso arriba de este silenciador, un tubo de diámetro ligeramente mayor que el de la tubería y provisto en sus dos extremos, respectivamente, de una entrada y una salida de fluido coaxiales entre sí y respecto al tubo, y , dentro de este tubo, una sucesión de diafragmas distribuídos en su longitud y que delimitan un paso de fluido que tiene una sección sensiblemente equivalente a la de la tubería.
