Abstract

La présente invention concerne un dispositif d'étanchéité par pression de fluide. Le dispositif d'étanchéité par pression de fluide destiné à assurer l'etanchéité entre une pièce fixe 18 et une pièce mobile 12 reliant deux enceintes 10, 11 soumises à des pressions différentes, est caractérisé en ce que l'une des deux pièces est munie sur au moins une partie de sa surface périphérique d'au moins une gorge ou rainure 17 orientée de manière à créer sous l'effet du mouvement de la pièce mobile une contre-pression entre les deux enceintes. La présente invention est utilisée dans les pompes, moteurs ou compresseurs.
