Title (EN) REINFORCED SEALING RINGS
(FR) BAGUES D'ÉTANCHÉITÉ RENFORCÉES
Abstract:
(EN) The present disclosure provides a sealing ring assembly having a sealing ring and a reinforcement, configured to seal a high-pressure region from a lower pressure region of a piston and cylinder device. The sealing ring may be segmented, and a metal layer, wire, or other reinforcement may be affixed to the ring. The reinforcement is placed into tension against the sealing ring, which is correspondingly placed into compression. The composite structure of a relatively brittle sealing ring and reinforcement provides for reduced tensile loads in the sealing ring, thus extending life and reducing the likelihood of failure. The brittle portion of the sealing ring assembly may include a polymer or ceramic such as graphite, which is relatively less strong in tension than compression.
(FR) La présente invention concerne un ensemble de bague d'étanchéité ayant une bague d'étanchéité et un renfort, configuré pour sceller une région à haute pression d'une région de basse pression d'un dispositif à piston et cylindre. La bague d'étanchéité peut être segmentée, et une couche métallique, un fil ou un autre renfort peuvent être fixés à la bague. Le renfort est placé en tension contre la bague d'étanchéité, qui est placée de manière correspondante en compression. La structure composite d'une bague d'étanchéité relativement fragile et d'un renfort permet de réduire les charges de traction dans la bague d'étanchéité, prolongeant ainsi la durée de vie et réduisant la probabilité de défaillance. La partie fragile de l'ensemble de bague d'étanchéité peut comprendre un polymère ou une céramique tel que du graphite, qui est relativement moins résistant à la tension qu'à la compression.
