Abstract
Joint d'étanchéité, notamment à action d'amortissement en des positions extrêmes. Il est constitué en matière élastique telle que du caoutchouc comportant un corps d'étanchéité annulaire de section transversale sensiblement en U, dont l'aile radialement intérieure forme une lèvre d'étanchéité circulaire et comporte dans la zone reliant les ailes au moins un bourrelet détanchéité circulaire faisant saillie par rapport au corps d'étanchéité dans le sens axial. Le corps d'étanchéité 9 comporte au moins une partie en relief 21 saillant radialement au-dessus de sa surface périphérique, et le bourrelet d'étanchéité 28 va en se rétrécissant pour former un appui linéaire sur le cylindre. Application en particulier aux vérins de manoeuvre pneumatiques ou hydrauliques.
