Abstract

La présente addition concerne une vanne à étanchéité encore améliorée par rapport au brevet principal. Cette vanne comprend essentiellement un arbre 19 comportant un collet 61 dont la face supérieure 62 définit une portée annulaire prévue en dessous d'une portée annulaire 63 solidaire du corps de vanne 10, de sorte que les fuites de fluide dans le corps de vanne exercent une force F tendant à appliquer le joint d'étanchéité 31 agencé dans la portée annulaire 62, contre la portée annulaire 63. La vanne selon la présente addition s'applique notamment à des conduites assurant le transport de fluide sous une pression très élevée.
