Abstract
BLOQUEO DE PERNO PARA UNION DE UN TUBO GUIA A UN CABEZAL DE UN CONJUNTO COMBUSTIBLE. CONSTA DE UN CABEZAL Y AL MENOS UN TUBO GUIA QUE SE EXTIENDE LONGITUDINALMENTE Y SE PROYECTA HACIA FUERA DESDE DICHO CABEZAL. ESTE TIENE UN TALADRO PASANTE Y UN REBORDE DEFINIDO DENTRO DE DICHO TALADRO ENFRENTADO AL TUBO GUIA, DIVIDIENDOLE EN DOS ZONAS. UNA DE ELLAS TIENE UNA SECCION TRANSVERSAL MAYOR QUE LA OTRA. CONSTA ADEMAS DE UN PERNO INSERTABLE A TRAVES DE DICHO TALADRO. UNO DE LOS EXTREMOS DEL PERNO TIENE UNA ROSCA COMPLEMENTARIA E INTERGRANABLE CON LA ROSCA DEFINIDA EN EL EXTREMO DEL TUBO GUIA.
