A buffer seal adapted for use in a seal assembly including at least a primary seal, the seal assembly being adapted to provide a fluid seal between two relatively moving machine elements, such as a piston or rod of a first machine element moving within a cylindrical bore of a second machine element. The buffer seal comprises a scaling element and a resiliently deformable biasing element. The material, shape, and/or volume of the biasing element are selected to provide a desired biasing force sufficient to maintain a surface of the sealing element in sealing contact with a surface of the first machine element and to simultaneously maintain another surface of the sealing element in sealing contact with a surface of the second machine element. The buffer seal may be further configured to inhibit the migration of system contaminants to the primary seal.

Cette invention concerne un joint amortisseur qui est con×u pour s'utiliser dans un ensemble joint comprenant au moins un joint primaire qui empÚche un fluide de passer entre deux ~l~ments m~caniques en mouvement l'un par rapport ~ l'autre, cas d'un piston ou d'une bielle dans un premier ~l~ment m~canique qui se d~place dans l'al~sage cylindrique d'un second ~l~ment m~canique. Le joint amortisseur comprend un ~l~ment d'~tanch~it~ et un ~l~ment de contrainte ~lastique et d~formable. La mati­re, la forme et/ou le volume de l'~l~ment de contrainte sont choisis de mani­re ~ fournir une force de contrainte suffisante pour maintenir une surface de l'~l~ment d'~tanch~it~ en contact avec le premier ~l~ment m~canique et ~ maintenir simultan~ment une autre surface dudit ~l~ment d'~tanch~it~ en contact avec une surface du second ~l~ment m~canique. Le joint amortisseur peut ~galement Útre con×u pour empÚcher des substances contaminantes d'atteindre le joint primaire.
