Title
(EN) SEAL WITH NON-METALLIC INTERFACE
(FR) JOINT AVEC INTERFACE NON MÉTALLIQUE
Abstract
(EN)
A seal for use between a first duct and a second duct and, the ducts having relative motion therebetween, includes a first plurality of fingers for attachment to the first duct to be disposed about one of the first duct and the second duct, a seal land attaching to about an other of the first duct and the second duct, and a seal attaching to the seal land and in contact with the plurality of fingers wherein one of the plurality of fingers and the seal is metallic and an other of the seal land or the plurality of fingers is non-metallic.
(FR)
Selon l'invention, un joint à utiliser entre une première conduite et une deuxième conduite, les conduites présentant un mouvement relatif entre elles, comprend une première pluralité de doigts permettant la fixation à la première conduite à placer autour de soit la première conduite, soit la deuxième conduite, une lèvre de joint s'attachant autour de l'autre desdites conduites, et un joint s'attachant à la lèvre de joint et en contact avec la pluralité de doigts, où un parmi la pluralité de doigts et le joint étant métallique et un autre parmi la lèvre de joint et la pluralité de doigts étant non métallique.
