Abstract

SE PRESENTA UN SISTEMA SECUNDARIO DE SUMINISTRO DE AIRE PARA UN VEHICULO QUE INCLUYA UN MOTOR (7) QUE TENGA UNA CAMARA DE CIGUEÑAL (8) QUE ESTE OPERATIVAMENTE CONECTADO A UN FILTRO DE AIRE (11) Y A UN SISTEMA DE ESCAPE QUE INCLUYA UN TUBO DE ESCAPE (14). EL SISTEMA COMPRENDE UNA BOMBA DE DIAFRAGMA (1) PROVISTA DE UNA CAMARA INTERIOR (4A, 4B, 4C) Y QUE TIENE UN CONDUCTO DE ENTRADA DE AIRE (9) Y UN CONDUCTO DE SALIDA DE AIRE (12) ESTANDO AMBOS COMUNICADOS CON LA CAMARA INTERIOR, UN DIAFRAGMA (2) DISPUESTO EN LA CAMARA INTERIOR PARA DIVIDIRLA EN UNA CAMARA DE DIAFRAGMA (3) Y UNA CAMARA DE BOMBA (4A, 4B, 4C), UN PRIMER MANGUITO (10) QUE CONECTA EL CONDUCTO DE ENTRADA DE AIRE Y EL FILTRO DE AIRE PARA INTRODUCIR AIRE SECUNDARIO DESDE EL FILTRO DE AIRE AL INTERIOR DE LA CAMARA DE LA BOMBA (4A), UN SEGUNDO MANGUITO (13) QUE CONECTA EL CONDUCTO DE SALIDA DE AIRE Y EL TUBO DE ESCAPE (14) PARA SUMINISTRAR EL AIRE SECUNDARIO AL INTERIOR DEL TUBO DE ESCAPE A TRAVES DEL CONDUCTO DE SALIDA, Y UN TERCER MANGUITO (6) QUE CONECTA LA CAMARA DE DIAFRAGMA DE LA BOMBA DE DIAFRAGMA Y LA CAMARA DEL CIGUEÑAL DEL MOTOR. EL AIRE SECUNDARIO SE SUMINISTRA AL INTERIOR DEL TUBO DE ESCAPE A TRAVES DE LA BOMBA DE DIAFRAGMA EN UNA CANTIDAD EN PROPORCION A LA MAGNITUD DE UNA OSCILACION DEL DIAFRAGMA (2) PROVOCADA DE ACUERDO CON LA VARIACION DE PRESION EN LA CAMARA DE CIGUEÑAL QUE SERA PROPORCIONAL A LA VELOCIDAD DE REVOLUCION DEL MOTOR. UNA VALVULA (5A, 5B) SE DISPONE ADEMAS EN LA CAMARA DE LA BOMBA (4A, 4B, 4C) PARA PERMITIR QUE EL AIRE SECUNDARIO SE INTRODUZCA EN EL INTERIOR DE LA CAMARA DE LA BOMBA FLUYENDO UNIDIRECCIONALMENTE DESDE EL CONDUCTO DE ENTRADA (9) HASTA EL CONDUCTO DE SALIDA (12).
