The invention relates to a piston pressure device with a sealing device (10) to seal areas of differing pressure. Said sealing device consists of a first elastomer component (12) and a second component made of material which is plastically deformable under the effect of pressure. Both components provide a seal for various pressures. Said device also comprises a piston (30) and a piston shaft (20). The piston (30) can move axially in relation to the piston shaft (20). The sealing device (10) is arranged in positive fit in a recess between the piston (30) and the piston shaft (20).
Dispositif de pression à piston doté d'une garniture d'étanchéité (10) destinée à séparer de manière étanche deux zones de pression différente. Ladite garniture comporte en tant que premier composant un élastomère (12) et en tant que second composant une matière plastiquement déformable sous l'effet de la pression. Les deux composants garantissent l'étanchéité en cas de différences variables de pression. Ledit dispositif comporte en outre un piston (30) et une tige (20) de piston, le piston (30) étant mobile axialement (20) par rapport à la tige de piston. La garniture d'étanchéité (10) est placée par liaison de forme dans un évidement ménagé entre le piston (30) et la tige (20) de piston.
