Patent

CA 2551014

The present invention relates to a multi-layered seal ring capable of expanding for installation onto a shaft, rod or other cylindrical member, and then once in position, provides a seal as though it were a continuous solid ring allowing for only a minimal amount of leakage over a wide temperature range. More specifically, the present invention relates to first and second annular or non-annular forms having gaps or fractures in their structure, wherein the first and second annular or non-annular forms are affixed to one another.

L'invention concerne un joint d'étanchéité multicouche capable de se dilater lorsqu'il est monté sur un arbre, une tige ou autre élément cylindrique et qui, une fois en position, procure une étanchéité comme s'il s'agissait d'un anneau solide continu, et ne présentant qu'une quantité minimale de fuite sur un vaste intervalle de température. Plus spécifiquement, l'invention concerne une première et une seconde formes annulaires, ou non annulaires, présentant des espaces ou des fractures dans leur structure, la première et la seconde formes annulaires ou non annulaires étant fixées l'une à l'autre.
