Abstract

EN LAS VALVULAS DE SOLENOIDE CONOCIDAS QUE TIENEN UN NUCLEO (1) RODEADO POR UNA BOBINA MAGNETICA (3) Y UNA ARMADURA (30) QUE ACTUA SOBRE UN CUERPO DE CIERRE DE LA VALVULA MEDIANTE UN TUBO DE CONEXION (28), LA CONEXION EN TUBO DE CONEXION Y EL CUERPO DE CIERRE DE LA VALVULA DURO (35) SE HACE POR SOLDEO. SIN EMBARGO, LA CONEXION NO ES SIEMPRE SEGURA Y FIDEDIGNA. POR EL CONTRARIO, EN LA NUEVA VALVULA, SE HACE PRIMERO, EN EL CUERPO DE CIERRE DE LA VALVULA METALICO (35), UNA SOLDADURA POR PUNTOS (40) QUE SE SOLDA DESPUES AL TUBO DE CONEXION METALICAMENTE MAS BLANDO (28) MEDIANTE UNA SEGUNDA SOLDADURA POR PUNTOS (41) HASTA QUE AL MENOS SE FORMA LA JUNTA DE LA SOLDADURA (39) QUE RODEA PARCIALMENTE ASEGURA UNA CONEXION SEGURA Y FIDEDIGNA ENTRE EL CUERPO DE CIERRE DE LA VALVULA (35) Y EL TUBO DE CONEXION (28). LA CONFIGURACION DE LA VALVULA ES PARTICULARMENTE APTA PARA VALVULAS DE INYECCION EN INSTALACIONES DE INYECCION DE COMBUSTIBLE.
