Abstract
Methods and systems are provided for a sealing device. In one example, a seal comprises a plurality of radial features and a plurality of axial features extending from a cylindrical body, the cylindrical body comprises a first material and a second material, wherein the second material is stiffer than the first material.
Claims20
A system, comprising:
- a seal comprising a plurality of radial features and a plurality of axial features extending from a cylindrical body, wherein a plurality of interior radial features extend into a central bore of the seal and a plurality of exterior radial features extend away from the central bore of the seal, the cylindrical body comprises a first material and a second material embedded within the first material, wherein the second material has a Z-shape and is stiffer than the first material, and a step feature arranged between the second material, an upper radial feature of the plurality of radial features, and an upper axial feature of the plurality of axial features, wherein the upper radial and axial features are respectively uppermost radial and axial projections of the seal, wherein the step feature is adjacent to a first extreme end of the second material axially higher than the upper radial feature and axially lower than the upper axial feature, and wherein the second material comprises a second extreme end, opposite the first extreme end and axially between the plurality of radial features.
A sealing device, comprising:
- a spine feature having a Z-shape, the spine feature comprising a stiff material encased in an elastomeric material, wherein a plurality of exterior radial features extends radially outward from the elastomeric material and a plurality of interior radial features extends radially inward from the elastomeric material toward a bore of the sealing device, and wherein an upper axial feature extends from a first end of the elastomeric material and wherein a lower axial feature extends from a second end of the elastomeric material, wherein the first end is opposite the second end, and a step feature arranged between the spine feature, an upper exterior radial feature of the plurality of exterior radial features, and the upper axial feature, wherein a first extreme end of the spine feature is adjacent to the step feature and axially between the upper exterior radial feature and the upper axial feature, wherein the upper exterior radial feature and the upper axial feature are respectively uppermost radial and axial projections of the sealing device, and a second extreme end of the spine feature, opposite the first extreme end, axially between the plurality of exterior radial features and the plurality of interior radial features.
A system, comprising:
- a seal comprising at least one upper axial feature configured to engage with a first surface, a plurality of exterior radial features and at least one lower axial feature configured to engage with a second surface outside a central bore of the seal, and a plurality of interior radial features configured to engage with a third surface inside the central bore of the seal;
- a spine feature comprising a Z-shape, embedded in a compressible material of the seal, the spine feature configured to provide a counterforce relative to a force of the first surface, the second surface, and the third surface;
- and
- a step feature arranged adjacent to a first extreme end of the spine feature and axially between an upper radial feature of the plurality of exterior radial features and the at least one upper axial feature, wherein the spine feature further comprises a second extreme end, axially below the first extreme end, and between the plurality of exterior radial features and the at least one upper axial feature.
