Abstract
Un outil de fond de trou, comme un bouchon provisoire, comporte un élément de garniture disposé sur un mandrin de loutil adjacent à un élément dactivation, comme un arrangement de cône et de glissière. Lélément de garniture comprend une garniture et au moins une bague détanchéité de fond. La garniture est composée de matériau de garniture et compressible sur loutil de fond de trou au moins en partie au moyen de lélément dactivation. La au moins une bague détanchéité de fond limite lextrusion de la garniture. La au moins une bague détanchéité de fond est moulée dans le matériau de garniture à une extrémité de la garniture adjacente à lélément dactivation. Préférablement, chaque extrémité de la garniture comporte au moins deux bagues détanchéité de fond moulées intégralement et des fentes dans les bagues détanchéité de fond adjacentes sont préférablement décalées aux extrémités.
