Abstract

EN VALVULAS ACCIONABLES ELECTROMAGNETICAMENTE CONOCIDAS LA AGUJA DE VALVULA SE COMPONE DE UN TRAMO DE ANCLAJE EN FORMA TUBULAR, UN TRAMO DE CASQUILLO DE VALVULA DE FORMA TUBULAR Y UN TRAMO DE MIEMBRO DE CIERRE DE VALVULA. EL COMBUSTIBLE CIRCULA CON ELLO EN EL INTERIOR DE LA AGUJA DE VALVULA HASTA EL TRAMO DEL MIEMBRO DE CIERRE DE VALVULA Y APARECE ENTONCES A TRAVES DE PERFORACIONES TRANSVERSALES EN LA AGUJA DE VALVULA EN DIRECCION HACIA EL ASIENTO DE VALVULA. LA NUEVA AGUJA (34) DE VALVULA SE CARACTERIZA DE TAL MODO, QUE EL TRAMO (36) DE ANCLAJE Y EL TRAMO (46) DE MIEMBRO DE CIERRE DE VALVULA CON EL TRAMO (38) DE AGUJA DE VALVULA UNIDO ESTAN CONFIGURADOS DE FORMA MACIZA. PARA GARANTIZAR UNA CORRIENTE DE COMBUSTIBLE EN DIRECCION DEL ASIENTO (22) DE VALVULA, SE HAN PREVISTO EN EL TRAMO (36) DE ANCLAJE AL MENOS DOS RANURAS AXIALES. LAS RANURAS AXIALES EN EL TRAMO (36) DE ANCLAJE ESTAN CONFIGURADAS DE TAL MODO, QUE EL COMBUSTIBLE QUE APARECE EN EL PERIMETRO EXTERIOR DEL TRAMO (38) DE AGUJA DE VALVULA PUEDE CIRCULAR A LO LARGO DE LA DIRECCION DEL ASIENTO (22) DE VALVULA. LA AGUJA DE VALVULA ES APROPIADA ESPECIALMENTE PARA VALVULAS DE INYECCION EN INSTALACIONES DE INYECCION DE COMBUSTIBLE DE MOTORES DE COMBUSTION INTERNA DE ENCENDIDO EXTERIOR CON MEZCLA COMPRIMIDA.
