Abstract

Silenciador con un resonador en derivación en el que el resonador en derivación (10) está formado por un canal exterior (1) que conduce el sonido un volumen de la caja que encierra una zona predeterminada, y en el que el canal que conduce el sonido (1) está unido con el resonador en derivación (10) a través de aberturas (6), las aberturas están formadas por elementos tubulares (6) que se extienden desde el canal que conduce el sonido (1) al volumen de la caja del resonador en derivación (10), caracterizado porque la zona con los elementos tubulares (6) dentro del canal que conduce el sonido (1) se introduce como pieza moldeada de inyección (5) entre los extremos (3, 4) del canal (1), y porque el volumen de la caja que rodea el resonador en derivación (10) se aplica con cada mitad de caja (7, 8) en cada extremo (3, 4) de canal (1) y los dos mitades de la caja (7, 8) se pueden montar juntas, incluyendo la pieza moldeada de plástico (5).
