Abstract

VALVULA CONTROLADA ELECTROMAGNETICAMENTE DESTINADA A SER UTILIZADA EN UN SISTEMA DE INYECCION DE COMBUSTIBLE DE MOTOR DE COMBUSTION INTERNA. UNA VALVULA DE CONTROL PARA SISTEMA DE INYECCION DE COMBUSTIBLE DE MOTOR INCLUYE UN ELEMENTO DE VALVULA (24) EN FORMA DE PLACA QUE PUEDE DESPLAZARSE EN UNA CAMARA DE ENTRADA (21) ENTRE UN PRIMER ASIENTO (19) Y UN SEGUNDO ASIENTO (23) EN LADOS OPUESTOS DEL ELEMENTO DE VALVULA. EL DIAMETRO DEL PRIMER ASIENTO ES INFERIOR AL DEL SEGUNDO Y RODEA UN PASO DE CIRCULACION DE REBOSAMIENTO (20). LA CAMARA DE ENTRADA ESTA CONECTADA DURANTE EL FUNCIONAMIENTO CON LA CAMARA DE BOMBEO DE UNA BOMBA DE COMBUSTIBLE. CUANDO EL ELEMENTO DE VALVULA ESTA EN CONTACTO CON EL SEGUNDO ASIENTO, SE FORMA UNA CAMARA DE CONTROL (25) QUE ESTA CONECTADA POR UN PASO RESTRINGIDO (26) CON LA CAMARA DE LA BOMBA. LA CIRCULACION DEL LIQUIDO A PARTIR DE LA CAMARA DE CONTROL SE REGULA POR MEDIO DE UN ELEMENTO DE VALVULA (28) QUE PUEDE SER DESPLAZADO POR UN ACTUADOR (29) Y QUE CONTROLA CONVENIENTEMENTE LA CIRCULACION A TRAVES DE UN ORIFICIO (27) FORMADO EN EL ELEMENTO DE VALVULA.
