Abstract

Dispositif d'étanchéité pour mécanisme à cylindre et piston destiné à assumer notamment la fonction d'un amortisseur. Il comprend une bague montée de manière amovible sur la tête 14 d'un cylindre 12 et portant un joint annulaire fendu qui entre en contact étanche avec la tige 15 d'un piston 11 mobile dans le cylindre 12. La bague peut être déplacée suffisamment sur la tige du piston pour faire apparaître le joint afin d'en permettre le démontage et la remise en place si cela est souhaité. Domaine d'application : amortisseurs hydrauliques pour centrale nucléaire.
