Abstract
An annular seal for use in sliding or translating applications is provided. An annular can comprises a metallic material formed into a ring. One or more ribs are disposed about an inner surface or an outer surface wall of the ring where the ribs provide a sliding sealing surface smaller having a reduced contact area relative to the width of the ring wall. The sliding sealing surface provides a seal against one or more sliding members. The rib-wall structure forms a circular beam providing greater structural integrity to the seal than would otherwise be possible.
Claims20
An annular seal for use between a first and a second sliding member, the seal comprising:
- an annular ring formed of a metallic material, where the annular ring is sized and dimensioned to have:
- (a) an inner cylindrical surface coaxial with an outer cylindrical surface,
- (b) a width (W) in the range from 0.1 inches to 6 inches, and
- (c) an outer diameter (OD) in the range from 0.1 inches to 12 feet;
- a rib protruding from and circumferentially disposed on the outer surface wherein the rib has a surface that is configured to provide a sliding sealing surface with one of the first and the second sliding members, and wherein the surface of the rib has a rib width (RW) of less than 50% of the width (W);
- a first flange and a second flange extending approximately 90 degrees from the inner surface and wherein the first and second flanges each have a thickness that is substantially different than the rib width;
- and
- wherein the first flange and second flange have ends, each end having a surface coaxial with the inner cylindrical surface that is configured to provide a sliding sealing surface with one of the first and second sliding members.
A sliding seal system comprising:
- first and second sliding members;
- an annular ring formed of a metallic material, where the annular ring is sized and dimensioned to have:
- (a) an inner cylindrical surface coaxial with an outer cylindrical surface,
- (b) a width (W) in the range from 0.1 inches to 6 inches, and
- (c) an outer diameter (OD) in the range from 0.1 inches to 12 feet;
- a rib protruding from and circumferentially disposed on the outer surface wherein the rib has a surface that is configured to provide a sliding sealing surface with one of the first and the second sliding members, and wherein the surface of the rib has a rib width (RW) of less than 50% of the width (W);
- a first flange and a second flange extending approximately 90 degrees from the inner surface and wherein the first and second flanges each have a thickness that is substantially different than the rib width;
- and
- wherein the first flange and second flange having ends, each end having a surface coaxial with the inner cylindrical surface that is configured to provide a sliding sealing surface with one of the first and second sliding members.
