Abstract
L'invention concerne un procédé et un dispositif de fermeture étanche d'un intervalle annulaire. Une pièce d'étanchéité annulaire est tournée de façon toroïdale d'un angle substantiel avant ou pendant sa mise en place dans l'intervalle, et elle peut réagir façon toroïdale sur les surfaces qui limitent l'intervalle, en assurant ainsi l'étanchéité. L'invention s'applique notamment à des joints de robinets à tournant sphérique.
