Abstract

SE PRESENTA UNA VALVULA QUE COMPRENDE UN EMBOLO (7) CONTROLADO POR UN ELECTROIMAN (2) QUE A SU VEZ CONTROLA EL FLUJO DEL COMBUSTIBLE A TRAVES DE UN ORIFICIO DE INYECCION (9); EL EMBOLO ESTA DEFINIDO POR UNA SUPERFICIE LATERAL CILINDRICA (11) QUE ENCAJA DE FORMA DESLIZANTE CON UNAS SUPERFICIES DE GUIA CILINDRICAS CORRESPONDIENTES (6) DE UN ASIENTO FORMADO EN EL CUERPO DE LA VALVULA (1). DE ACUERDO CON LA INVENCION, EL BARICENTRO (G) DEL EMBOLO DESCANSA EN UN PLANO (SG) DE LA VALVULA PERPENDICULAR AL EJE DE LA VALVULA, Y LA DISTANCIA (D) ENTRE DICHO PLANO (SG) Y EL PLANO MEDIO (SM) DE LA SUPERFICIE DE LA GUIA CILINDRICA (6) ES MENOR A 2 MM.
