A sealing ring is disclosed for radially sealing two coaxial surfaces. The sealing ring has an annular convolution with a first radially facing sealing surface and a pair of annular leg portions forming second and third radially facing sealing surfaces. Each of the leg portions are provided with an annular bend to increase the radial resiliency of the seal. In an alternate embodiment, each of the leg portions of the sealing ring has a pair of annular bends. In yet another embodiment, the sealing ring is constructed of a pair of plies or layers.

[ What is claimed is:] [1.] A sealing ring for sealing two coaxial surfaces relative to one another, comprising:an annular convolution portion be configured to form a first bending area which has a first annular end and a second annular end with a convex annular surface and a concave annular surface extending therebetween, and said convex surface extending 360.degree. to form a first radial sealing surface facing in a first radial direction;a first annular leg portion extending outwardly from said first end of said convolution portion to a first free end, and having a second radial sealing surface facing in a second radial direction substantially opposite to said first radial sealing surface of said convolution portion and a first annular bent section located between said second radial sealing surface and said convolution portion, said first annular bent section being configured to form a second bending area; anda second annular leg portion extending outwardly from said second end of said convolution portion to a second free end, and having a third radial sealing surface facing in said second radial direction and a second annular bent section located between said third radial sealing surface and said convolution portion, said second annular bent section being configured to form a third bending area,said first annular bent section being arranged axially between said first radial sealing surface and said second radial sealing surface, said second annular bent section being arranged axially between said first radial sealing surface and said third radial sealing surface, said first and second annular bent sections being further arranged radially between said first radial sealing surface and said second and third radial sealing surfaces such that radial compression of said sealing ring causes bending to primarily occur at said first, second and third bending areas to permit said sealing ring to decrease in its radial direction and increase in its axial direction.
