Title (EN) SEALING RING ASSEMBLIES CONFIGURED FOR PRESSURE LOCKING
(FR) ENSEMBLES BAGUES D'ÉTANCHÉITÉ CONFIGURÉS POUR UN VERROUILLAGE SOUS PRESSION
Abstract:
(EN) A sealing ring (200) includes a first sealing element (220) having a first mating surface and a second sealing element (230) having a second mating surface. A high-pressure boundary (250) extends across at least a portion of the first sealing element and across at least a portion of the second sealing element, and a low-pressure boundary (252) extends across at least a portion of the first sealing element and across at least a portion of the second sealing element. The first mating surface, the second mating surface, or both, includes a recess (221) open to the low-pressure boundary and not open to the high-pressure boundary. The recess may include a groove (223), for example. The first mating surface is sealed against the second mating surface by a first force (290) acting on the first sealing element and a second force (291) acting on the second sealing element. These forces act to pressure-lock the assembly.
(FR) La présente invention concerne une bague d'étanchéité (200) comprenant un premier élément d'étanchéité (220) ayant une première surface de contact et un second élément d'étanchéité (230) ayant une seconde surface de contact. Une enveloppe haute pression (250) s'étend à travers au moins une partie du premier élément d'étanchéité et à travers au moins une partie du second élément d'étanchéité, et une enveloppe basse pression (252) s'étend à travers au moins une partie du premier élément d'étanchéité et à travers au moins une partie du second élément d'étanchéité. La première surface d'accouplement, la seconde surface d'accouplement, ou les deux, comprennent un évidement (221) ouvert vers l'enveloppe basse pression et non ouvert vers l'enveloppe haute pression. L'évidement peut comprendre une rainure (223), par exemple. La première surface d'accouplement est scellée contre la seconde surface d'accouplement par une première force (290) agissant sur le premier élément d'étanchéité et une seconde force (291) agissant sur le second élément d'étanchéité. Ces forces agissent pour verrouiller l'ensemble sous pression.
