Abstract

L'invention concerne l'étanchéité des vérins hydrauliques et pneumatiques. Elle se rapporte à un vérin qui a un cylindre comportant une fente longitudinale destinée au passage d'un organe de commande. La fente est fermée de façon étanche par une bande souple. Selon l'invention, la face interne du cylindre, de part et d'autre de la fente, a une courbure inférieure à celle du reste de la surface du cylindre. La bande a des chanfreins à ses bords. Application aux vérins hydrauliques et pneumatiques.
