An improved resilient type sealing member for use at least in an application which requires both sealing of an annular space between an inner surface of a first member and an adjacent outer surface of a second member at least partially disposed for reciprocal movement within such first member and for providing support to such second member during such reciprocal movement. The improved resilient type sealing member includes a generally round resilient disc-like member having each of a first predetermined diameter and a predetermined thickness. Such resilient disc-like member includes a pair of radially opposed and substantially flat parallel side portions. A first groove, having a first predetermined shape and a first predetermined depth, is formed in a first one of such pair of radially opposed and substantially flat parallel side portions. Such first groove being disposed closely adjacent an outer edge of the resilient disc-like member. A second groove, having a second predetermined shape and a second predetermined depth, is formed in a second one of such pair of side portions. This second groove is disposed substantially radially opposite the first groove and an aperture, having a second predetermined diameter, is formed substantially through an axial center of such resilient disc-like member.

Élément de scellement élastique amélioré pour servir dans le cas d'une application nécessitant le scellement d'un espace annulaire entre une surface interne d'un premier élément et une surface externe adjacente d'un deuxième élément au moins partiellement disposé pour qu'il y ait mouvement réciproque dans le premier élément et pour servir d'appui au deuxième élément pendant le mouvement du premier élément. L'élément de scellement élastique amélioré comprend un élément rond élastique en forme de disque dont le diamètre et l'épaisseur sont prédéterminés. L'élément élastique en forme de disque comprend une paire de parois latérales, parallèles, plates et radialement opposées. Une première rainure, d'une forme et d'une profondeur prédéterminées, est formée dans l'une des parois latérales, parallèles, plates et radialement opposées. Cette première rainure se trouve très rapprochée du rebord extérieur de l'élément élastique en forme de disque. Une deuxième rainure, d'une forme et d'une profondeur prédéterminées, est formée dans une autre des parois latérales, parallèles, plates et radialement opposées. Cette deuxième rainure est radialement à l'opposé de la première rainure tandis qu'une ouverture d'un second diamètre prédéterminé est formée dans un centre axial de l'élément élastique en forme de disque.
