Abstract

L'invention concerne un dispositif de garniture qui comprend un élément de garniture élastomère qui est en appui sur un manchon interne qui entoure un mandrin interne central. Le manchon interne et le mandrin interne sont orientés à un angle de départ par rapport à l'axe central de l'outil, permettant ainsi de fournir un ensemble rampe qui aide à fixer le dispositif de garniture. Une bague d'ancrage et une bague de retenue sont disposées sur des côtés axiaux opposés de l'élément de garniture et viennent en contact avec l'élément tubulaire environnant.
