Abstract

EN UN AMORTIGUADOR DE SONIDOS PARA MAQUINAS MOTRICES DE COMBUSTION, ESPECIALMENTE PARA MOTORES DE DOS ACTOS HAY INSTALADAS EN LA CJA EXTERIOR (1) PIEZAS DE LA CAJA INTERIOR (2, 13, 16), CUYA PARED LIMITA CAMARAS (3, 8, 14, 15), QUE ATRAVIESAN LA FILA DE LOS GASES DE ESCAPE SOBRE QUEBRAMIENTOS (7, 19 Y 17) A LAS PAREDES (2, 13, 16). LA PRIMERA CAMARA EN SENTIDO DEL ATRAVESAMIENTO ESTA FORMADA POR UN TUBO AGUJEREADO (2), QUE ESTA DISPUESTO DENTRO DE UN EMBUDO (13), QUE FORMA LA SEGUNDA CAMARA. SOBRE EL EMBUDO (13) Y EN LA CAJA EXTERIOR (1) SE AJUSTA UNA PARED QUE SE DESVIA EN EL SENTIDO DEL EJE Y ESTA FORMADA CON AL MENOS UN QUEBRAMIENTO, QUE SE SEPARA LA ULTIMA CAMARA DE LA PENULTIMA EN SENTIDO DE ATRAVESAMIENTO. AMBAS CAMARAS ESTAN CERRADAS POR UNA PLACA (18) AGUJEREADA, TRANSVERSAL PARA EL EJE DE LA CJA EXTERIOR (1). EL LUGAR (22) ENTRE LA PLACA AGUJEREADA Y UNA COFIA (21), QUE CONSTA DE MATERIAL LLENO ESTA RELLENADA CON MATERIAL INSONORIZANTE COMO POR EJEMPLO, LANA MINERAL O LANA DE ACERO INOXIDABLE, POR LO CUAL SE OBTIENE UNA AMORTIGUACION DE SONIDOS. SOBRE LA ULTIMA CAMARA (15) SE AJUSTA UNA ABERTURA DE ESCAPE, QUE ESTA FORMADA POR TUBOS (20), QUE SE CONSIGUEN DEL LUGAR (22) ENTRE LA PLACA AGUJEREADA (18) Y LA COFIA (21). ANTES DE LA PRIMERA CAMARA CONSTA EN LA CAJA EXTERIOR UN LUGAR LIBRE (25), QUE POSIBILITA EL SOPORTE DE UN CATALIZADOR.
