Abstract

LA VALVULA INCLUYE UNA CAJA TUBULAR (2), UN ELECTROIMAN (3) DEFINIDO POR UNA MATRIZ TUBULAR (4) Y UN DEVANADO ELECTRICO (5), UN CUERPO TUBULAR (6), UNA PARTE (7) EL CUAL CONSTITUYE EL NUCLEO DEL CIRCUITO MAGNETICO DEFINIDO EN LA VALVULA, UN MIEMBRO MOVIL OBTURADOR DE LA VALVULA (8) QUE CONTROLA EL FLUJO DE COMBUSTIBLE A TRAVES DE UN ORIFICIO DE INYECCION (11) Y UNA ARMADURA TUBULAR (12) ATRAIDA POR LA PARTE (7) DEL CUERPO (6) CUANDO EL ELECTROIMAN (3) ES EXCITADO Y POR ELLO DETERMINA LA CARRERA DEL MIEMBRO OBTURADOR DE LA VALVULA (8). LA CARACTERISTICA PRINCIPAL DE LA VALVULA RESIDE EN EL HECHO DE QUE INCLUYE UN ENCLAVAMIENTO AXIAL ENTRE LA CAJA (2) Y LA MATRIZ (4), TENIENDO ESTE ENCLAVAMIENTO POR LO MENOS UNA LENGUETA (36) FORMADO EN LA CAJA (2) Y ENGANCHANDO EN UNA RANURA (25) DE LA MATRIZ (4).THE VALVE INCLUDES A TUBULAR CASE (2), AN ELECTROMAGNET (3) DEFINED BY A TUBULAR MATRIX (4) AND AN ELECTRIC WINDING (5), A TUBULAR BODY (6), A PART (7) WHICH CONSTITUTES THE NUCLEUS OF THE CIRCUIT DEFINED MAGNETIC IN THE VALVE, A MOBILE MEMBER SEALING THE VALVE (8) THAT CONTROLLES THE FLOW OF FUEL THROUGH AN INJECTION HOLE (11) AND A TUBULAR ARMOR (12) ATTRACTED BY PART (7) OF THE BODY (6) ) WHEN THE ELECTROMAGNET (3) IS EXCITED AND THEREFORE DETERMINES THE CAREER OF THE VALVE SHUTTER MEMBER (8). THE MAIN CHARACTERISTIC OF THE VALVE RESIDES IN THE FACT THAT IT INCLUDES AN AXIAL INTERLOCK BETWEEN THE BOX (2) AND THE MATRIX (4), HAVING THIS INTERLOCK AT LEAST ONE TAB (36) FORMED IN THE BOX (2) AND HITCHING IN A SLOT (25) OF THE MATRIX (4).
