Abstract
SE DEFORMA POR PLEGADO HACIA EL INTERIOR CADA UNA DE LAS ZONAS DE LA VIROLA (25) QUE CONSTA DE UNA PARTE DEFORMADA (29) PROTUBERANTE RADIALMENTE, DE MANERA QUE SE EXTRAIGA LA PARTE DEFORMADA (29) DE UNA CAVIDAD (22) CORRESPONDIENTE DE LA CONTERA. SE EXTRAE A CONTINUACION EL MANGUITO DE BLOQUEO (20) POR TRACCION DEL MISMO (20) EN LA DIRECCION AXIAL (ZZ'') DEL TUBO-GUIA (4). PREFERENTEMENTE, LA VIROLA (25) ESTA CONSTITUIDA POR UNOS SECTORES CILINDRICOS SEPARADOS POR RANURAS DISPUESTAS DE ACUERDO CON LAS GENERATRICES DE LA VIROLA (25). UNA HERRAMIENTA (31) PERMITE REALIZAR EL PLEGADO DE LOS SECTORES DE LA VIROLA (25) Y EL PINZAMIENTO DE ESTOS SECTORES PARA REALIZAR LA EXTRACCION DEL MANGUITO DE BLOQUEO (20). LA EXTRACCION SE EFECTUA BAJO EL AGUA EN UNA PISCINA DE ALMACENAMIENTO DE COMBUSTIBLE.
