摘要： 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. Finally, an aperture, having a second predetermined diameter, is formed substantially through an axial center of such resilient disc-like member.
