Abstract

VALVULA INYECTORA DE COMBUSTIBLE PARA UN MOTOR DE COMBUSTION INTERNA. LA VALVULA DISPONE DE UNA AGUJA DE VALVULA (27), QUE ES ATRAIDA HACIA UN NUCLEO, POR MEDIO DE UN INDUCIDO CONECTADO CON LA MISMA, CUANDO SE EXCITA UNA BOBINA MAGNETICA, LEVANTANDO LA AGUJA DE LA VALVULA (27) CON UN ASIENTO DE VALVULA (48). EL ASIENTO HERMETICO (47) ES REDONDEADO (90), CUYO CONTORNO SIGUE LA SUPERFICIE LATERAL EXTERNA DE UN TORO IMAGINARIO (94), EL CUAL PUEDE PRESENTAR LA SECCION TRANSVERSAL DE UN CIRCULO (93) O DE UNA ELIPSE (96). MEDIANTE EL RADIO DEL REDONDEADO (90), QUE CONDUCE A UN CONTACTO FISICO LINEAL MARCADO ENTRE LA AGUJA DE LA VALVULA (27) Y LA SUPERFICIE DE ASIENTO DE LA VALVULA (48), LA TENDENCIA DE LA AGUJA DE LA VALVULA (27) CON RESPECTO AL <PEGADO> HIDRAULICO SOBRE LA SUPERFICIE DE ASIENTO DE LA VALVULA (48) ES MUCHO MENOR QUE EN EL CASO DE LAS VALVULAS DE INYECCION DE COMBUSTIBLE CONOCIDAS HASTA AHORA.
