Abstract

L'invention concerne des corps creux déformables et réversibles, utilisés pour actionner des dispositifs de maintien et/ou de tension dans des cylindres, notamment des cylindres de presse. Ils nécessitent une conduite de moyen de pression étanche et simple à monter. L'invention vise à réaliser une conduite de moyen de pression dans le corps creux (01) à la fois simple, rapide à monter et autoétanchéifiante. A cet effet, les surfaces d'étanchéification et les surfaces de séparation entre le cylindre (02) et le corps creux (01) amovible sont pratiquement parallèles l'une par rapport à l'autre et pratiquement perpendiculaires par rapport au sens de la pression (P) créée par l'alimentation en moyen de pression. Dans un mode de réalisation préféré, les surfaces d'étanchéification et les surfaces de séparation ne s'interpénètrent pas.
