Abstract

La présente invention concerne un système hydraulique (1) comportant : - une chambre de compression (8) pouvant être soumise à la pression d'un fluide hydraulique, - un piston (10) mobile dans la chambre de compression (8) selon un axe (Z), - au moins un joint d'étanchéité (30) disposé entre le piston (10) et une paroi de la chambre de compression (8), avec une position axiale qui varie circonférentiellement autour de l'axe (Z), de façon à compenser des contraintes non axisymétriques induites par la pression du fluide.
