Abstract

EN UN CONJUNTO COMBUSTIBLE RECONSTITUIBLE, UN CABEZAL SUPERIOR QUE LLEVA UNA ESTRUCTURA PARA MONTAR LA PLACA ADAPTADORA DEL CABEZAL SUPERIOR EN UNION DE BLOQUEO DESMONTABLE SOBRE LAS POSCIONES EXTREMAS SUPERIORES DE LOS TUBOS GUIA, INCLUYE VARIAS MEJORAS. PRIMERO, UN TUBO DE BLOQUEO SE MONTA DENTRO DE LA PORCION EXTREMA SUPERIOR DEL TUBO GUIA CON MOVIMIENTO ENTRE UNA POSICION DE BLOQUEO SUPERIOR, DONDE LA PLACA ADAPTADORA Y LA PORCION EXTREMA SUPERIOR DEL TUBO GUIA SE MANTIENEN EN EL ACOPLAMIENTO DE BLOQUEO, Y UNA POSICION DE DESBLOQUEO INFERIOR, DONDE LA PLACA ADAPTADORA SE LIBERA DE LA PORCION EXTREMA SUPERIOR DEL TUBO GUIA. TAMBIEN, UNA PLURALIDAD DE PROYECCIONES SE UNEN EN EL TUBO DE BLOQUEO DE MANERA QUE SE EXTIENDEN HACIA FUERA DE EL Y A TRAVES DE RANURAS AXIALES DEFINIDAS EN LA PORCION EXTREMA SUPERIOR DEL TUBO GUIA. LAS PROYECCIONES PUEDEN DEFORMARSE ELASTICAMENTE PARA ACOPLARSE Y LIBERARSE DEUNA MUESCA DEL TALADRO PASANTE DE LA PLACA ADAPTADORA.
