Abstract

SE PROPONE UN VALVULA DE INYECCION DE COMBUSTIBLE CON TAMIZ (10) DE PULVERIZACION PARA SUMINISTRO DE COMBUSTIBLE O MEZCLA DE COMBUSTIBLE/GAS A MOTORES DE COMBUSTION INTERNA, QUE SE CARACTERIZA DE TAL MODO QUE SE ASEGURA UNA CALIDAD DE ROCIADO PARTICULARMENTE ALTA Y UN ACONDICIONAMIENTO NOTABLE DEL COMBUSTIBLE. ADICIONALMENTE EL TAMIZ (50) DE PULVERIZACION FORMA UNA PANTALLA DE PROTECCION CONTRA FORMACION DE HIELO, TAPONAMIENTO Y DEPOSITOS DE SUSTANCIAS QUIMICAS DENTRO DE LA VALVULA DE INYECCION DE COMBUSTIBLE. EL TAMIZ (50) DE PULVERIZACION, QUE TIENE UNA FORMA DE BOMBEO CONCAVA CON PERFIL DE CONCHA, ESTA MONTADO POR DEBAJO DE AL MENOS UN AGUJERO (15) DE INYECCION, VISTO EN LA DIRECCION DE FLUJO DEL COMBUSTIBLE. LA ZONA (60) CIRCUNFERENCIAL EXTERIOR DEL TAMIZ (50) DE PULVERIZACION ESTA FUNDIDA DENTRO DE LA CAPERUZA (40) PROTECTORA PROVISTA EN EL EXTREMO POR DEBAJO DE LA VALVULA DE INYECCION DE COMBUSTIBLE. LA CAPERUZA (40) PROTECTORA DISPONE DE UN DENTADO (62) PROTECTOR QUE SE EXTIENDE MASDEBAJO QUE EL AREA (56) MAS PROFUNDA DEL TAMIZ (50) DE PULVERIZACION, PARA PROTEGERLO CONTRA INFLUENCIAS MECANICAS. CUANDO SE INYECTA COMBUSTIBLE, UNA CANTIDAD PARCIAL DE COMBUSTIBLE LLEGA A ESTA ZONA (56) MAS PROFUNDA INDICADA Y FORMA UNA CANTIDAD RELATIVA DE LIQUIDO, AL QUE SE AÑADE NUEVO COMBUSTIBLE. ESTA DISPOSICION PERMITE UN ROCIADO IDEAL DE COMBUSTIBLE EN GOTITAS MAS PEQUEÑAS.
