Abstract

Ce dispositif comprend un mandrin exerçant une traction ou une poussée sur une tige. Il comprend un corps 26 dans lequel un trou 28 est formé en plusieurs passages 30 pratiqués dans le corps de manière à traverser celui-ci en communication avec le trou central, plusieurs mâchoires mobiles 32 montées chacune à pivotement dans l'un des passages, ainsi que des moyens élastiques 38 qui tendent à amener les mâchoires dans leur position active, une tige creuse de piston 44 d'un dispositif à cylindre-piston hydraulique 46 étant fixée concentriquement sur le corps du dispositif. Ce dispositif convient par exemple pour extraire des tubes d'un condenseur.
