Abstract

L'INVENTION CONCERNE UN AMORTISSEUR IMMERGE DANS UN FLUIDE AUTORISANT LES MOUVEMENTS LENTS MAIS PROVOQUANT UN BLOCAGE A L'ENCONTRE DES MOUVEMENTS RAPIDES D'UN ELEMENT MOBILE OU DEFORMABLE PAR RAPPORT A UN ELEMENT FIXE ET RIGIDE. L'AMORTISSEUR COMPREND UN CYLINDRE DIRIGE SUIVANT UNE DIRECTION DE DEPLACEMENT DE L'ELEMENT MOBILE ET EN APPUI SUR L'UN DES DEUX ELEMENTS ET UN PISTON EN APPUI PAR L'UNE DE SES EXTREMITES SUR L'AUTRE ELEMENT. LE PISTON EST MOBILE DANS LA CHAMBRE DU CYLINDRE QUI EST REMPLIE DE FLUIDE ET COMPORTE UNE OUVERTURE DE FUITE. LE CYLINDRE A UNE PAROI EPAISSE DE GRANDE RIGIDITE. LE PISTON EST ENGAGE DANS LE CYLINDRE AVEC UN LEGER JEU RADIAL METTANT LA CHAMBRE DU CYLINDRE EN COMMUNICATION AVEC LE FLUIDE DANS LEQUEL IL BAIGNE. LE PISTON EST CREUX ET A UNE PAROI DE FAIBLE EPAISSEUR DEFORMABLE RADIALEMENT SOUS L'EFFET D'UNE PRESSION TELLE QUE CREEE PAR UN DEPLACEMENT RAPIDE ENTRE LE CYLINDRE ET LE PISTON, AVEC UNE AMPLITUDE DE DEFORMATION ELASTIQUE VOISINE DU JEU RADIAL ENTRE CYLINDRE ET PISTON. L'INVENTION S'APPLIQUE, EN PARTICULIER, AU MAINTIEN DES ASSEMBLAGES COMBUSTIBLES DANS LA PISCINE DU COMBUSTIBLE USE D'UN REACTEUR NUCLEAIRE.
