Abstract

DISPOSITIVO SILENCIADOR PARA GASES DE ESCAPE. CONSISTE EN UNA CAJA TUBULAR (4) CON UNA ENTRADA (30) Y UNA SALIDA (36) FORMADAS POR UN CUERPO DOBLE TUBULAR TAMBIEN UNIDO LONGITUDINALMENTE EN SU PARTE CENTRAL, EL CUAL ESTA PERFORADO CON AGUJEROS (62) Y ENTRE EL Y LA PARED INFERIOR DE LA CAJA EXISTE UN CANAL ANULAR LONGITUDINAL DE CIRCULACION (31) POR EL QUE FLUYE EL GAS SEGUN LAS FLECHAS A TRAZOS. ENTRE ESTE CANAL (31) Y LA CARCASA (4) EXISTEN DOS CAPAS AISLANTES, UNA PRIMERA, ACUSTICA, Y UNA SEGUNDA, TERMICA. LAS FLECHAS GRUESAS INDICAN LA CIRCULACION DEL GAS EN LA ENTRADA Y SALIDA, ASI COMO SU ACCESO Y SALIDA DE UNA CAMARA DE EXPANSION (66) EN LA QUE SE PRODUCE UNA PRIMERA ABSORCION SONORA Y TERMICA A TRAVES DE LA EXPANSION Y DE LOS TALADROS (68) Y EL MATERIAL AISLANTE (70). LA OTRA AMORTIGUACION SONORA SE PRODUCE AL CIRCULAR EL GAS A TRAVES DE LOS TALADROS (62, 64), EL CANAL (31 Y 38). EXISTEN VARIANTES EN SU CONSTRUCCION. DE APLICACION EN MOTORES DE COMBUSTION INTERNA.
