Abstract

Il s'agit d'un vérin comportant un piston 23 qui, monté mobile dans un corps creux 10 et y définissant une chambre 25, est annulairement relié audit corps creux 10 par une membrane déformable 24 fermant de manière étanche ladite chambre 25, le piston 23 correspondant ayant au moins une portée de guidage 43, 44 disposée à l'intérieur de cette chambre 25. Suivant l'invention, la membrane déformable 24 est constituée par un soufflet réalisé en un matériau à faible taux d'allongement, par exemple en métal. Application notamment à la réalisation de vérins émetteurs et/ou récepteurs pour commande hydraulique d'embrayage.
