Abstract

L'invention concerne un joint flexible à appliquer entre des organes dont un a un mouvement réciproque par rapport à l'autre, et il comprend un élément annulaire formé en un matériau élastique qui est stable par rapport à sa configuration préétablie. Selon l'invention, l'élément 1 des bords interne et externe 6 et 4 qui sont relativement plus épais qu'une âme intermédiaire 8 int gralement connectée, qui s'étend entre les bords, et dans la configuration préétablie, les bords interne et externe sont axialement décalés l'un par rapport à l'autre. L'invention s'applique notamment aux pompes.
