Title (EN) PISTON SEALING RING ASSEMBLY HAVING A GAP COVER ELEMENT
(FR) ENSEMBLE BAGUE D'ÉTANCHÉITÉ DE PISTON AYANT UN ÉLÉMENT DE RECOUVREMENT D'ESPACE
Abstract:
(EN) The present disclosure provides a sealing ring assembly having a ring and one or more gap cover elements, configured to seal a high-pressure region from a lower pressure region of a piston and cylinder device. The ring may be segmented, and the gap cover elements may engage with interfaces between the ring segments. The gap cover elements are configured to move radially outward and wear as the ring wears. The gap cover elements may include, for example, wedge- shaped features that engage with corresponding wedge recesses in the interfaces. The sealing ring assembly may include a high-pressure boundary and a low-pressure boundary. As the sealing ring wears, the gap cover elements stay engaged with the interfaces, so that ring gaps do not form on the low pressure boundary.
(FR) La présente invention concerne un ensemble bague d'étanchéité ayant une bague et un ou plusieurs éléments de recouvrement d'espace, conçus pour sceller une zone haute pression à partir d'une zone basse pression d'un dispositif à piston et cylindre. La bague peut être segmentée, et les éléments de recouvrement d'espace peuvent venir en prise avec des interfaces entre les segments de bague. Les éléments de recouvrement d'espace sont configurés pour se déplacer radialement vers l'extérieur et s'user au fur et à mesure que la bague s'use. Les éléments de recouvrement d'espace peuvent comprendre, par exemple, des éléments en forme de coin qui viennent en prise avec des évidements de coin correspondants dans les interfaces. L'ensemble bague d'étanchéité peut comprendre une enveloppe haute pression et une enveloppe basse pression. Au fur et à mesure de l'usure de la bague d'étanchéité, les éléments de recouvrement d'espace restent en prise avec les interfaces, de sorte que des espaces annulaires ne se forment pas sur l'enveloppe basse pression.
