Abstract
L'INVENTION CONCERNE LA TECHNIQUE NUCLEAIRE. LE GRAPPIN FAISANT L'OBJET DE L'INVENTION EST DU TYPE COMPRENANT UN CORPS 3 DANS LEQUEL EST PLACE UN COULISSEAU 4 MONTE MOBILE PAR RAPPORT AUDIT CORPS ET ENTRANT EN CONTACT AVEC DES GRIFFES 7 DONT CHACUNE EST ARTICULEE A L'UNE DE SES EXTREMITES DUDIT CORPSET DONT L'AUTRE EXTREMITE COMPORTE UNE DENT 8 S'ENGAGEANT DANS UN ALESAGE 14 DE LA TETE DE L'ASSEMBLAGE COMBUSTIBLE 15 LORS DE L'OUVERTURE DESDITES GRIFFES SOUS L'EFFET DU DEPLACEMENT RELATIF DU COULISSEAU ET DU CORPS, ET EST CARACTERISE EN CE QUE LE COULISSEAU COMPORTE DES RAINURES LONGITUDINALES 11 DANS CHACUNE DESQUELLES EST LOGEE UNE GRIFFE CORRESPONDANTE, LA PAROI EN BOUT INFERIEURE 12 DE CHACUNE DESDITES RAINURES ETANT INCLINEE PAR RAPPORT A L'AXE LONGITUDINAL DU GRAPPIN ET ENTRANT EN CONTACT AVEC LA DENT DE LA GRIFFE CORRESPONDANTE POUR ASSURER L'OUVERTURE DES GRIFFES LORS DUDIT DEPLACEMENT RELATIF. L'INVENTION S'APPLIQUE NOTAMMENT AUX EQUIPEMENTS DE RECHARGEMENT DES REACTEURS NUCLEAIRES DONT LES ASSEMBLAGES COMBUSTIBLES COMPORTENT UNE TETE AVEC UN ALESAGE INTERIEUR POUR LES GRIFFES DU GRAPPIN DE LA MACHINE DE RECHARGEMENT.
