Abstract

EL DISPOSITIVO CONSTA DE UNA BARRA FIJADA A UN ELEMENTO DE SUJECION Y DE ELEVACION SITUADO POR ENCIMA DE LA PISCINA EN LA QUE ESTA SUMERGIDO EL ENSAMBLAJE COMBUSTIBLE. LA BARRA CONSTA, AL MENOS, DE UN EXTREMO INFERIOR (32) CUYO DIAMETRO ES INFERIOR AL DIAMETRO INTERIOR DEL MANGUITO DE BLOQUEO (25). ESTE EXTREMO (32) TIENE UNA PERFORACION CENTRAL (40) Y AL MENOS DOS ABERTURAS RADIALES (56) EN CADA UNA DE LAS CUALES HAY UNA GARRA DE SUJECION (57). UN VASTAGO (41) QUE SE DESLIZA POR LA PERFORACION AXIAL (40) PERMITE CONTROLAR LA EXTRACCION DE LAS GARRAS. EL DESPLAZAMIENTO VERTICAL DE LA BARRA PERMITE EXTRAER EL MANGUITO DE BLOQUEO (25).
