Abstract
A seal assembly for providing a seal between a first component and a second component. The seal assembly includes a seal ramp associated with one of the components and a seal element associated with the other of the components. The seal ramp has an inclined seal ramp surface having a lower end and an upper end. The seal element is engaged with the seal ramp surface to provide the seal. The seal ramp and the seal element are movable relative to each other to enable the seal element to move along the seal ramp surface toward the upper end of the seal ramp surface. A seal energizing device urges the seal element toward the upper end of the seal ramp surface.
Claims23
A seal assembly for providing a seal between a first component and a second component, wherein the seal assembly has a seal assembly axis, the seal assembly comprising:
- (a) a seal ramp associated with one of the first component and the second component, wherein the seal ramp has a seal ramp surface, wherein the seal ramp surface has a lower end and an upper end which are axially spaced along the seal assembly axis, and wherein the seal ramp surface is inclined relative to the seal assembly axis between the lower end of the seal ramp surface and the upper end of the seal ramp surface;
- (b) a seal element associated with the other of the first component and the second component, wherein the seal element is engaged with the seal ramp surface in order to provide the seal, and wherein the seal ramp and the seal element are movable relative to each other in order to enable the seal element to move along the seal ramp surface toward the upper end of the seal ramp surface;
- and
- (c) a seal energizing device for urging the seal element toward the upper end of the seal ramp surface.
A seal assembly for providing a seal between a shaft and a housing, wherein the seal assembly has a seal assembly axis, wherein the shaft has a shaft axis, wherein the seal assembly axis is parallel with the shaft axis, and wherein the shaft is adapted to rotate relative to the housing about the shaft axis, the seal assembly comprising:
- (a) a seal ramp associated with the shaft, wherein the seal ramp has a seal ramp surface, wherein the seal ramp surface has a lower end and an upper end which are axially spaced along the seal assembly axis, and wherein the seal ramp surface is inclined relative to the seal assembly axis between the lower end of the seal ramp surface and the upper end of the seal ramp surface;
- (b) a seal element associated with the housing, wherein the seal element is engaged with the seal ramp surface in order to provide the seal, and wherein the seal element is movable relative to the seal ramp in order to enable the seal element to move along the seal ramp surface toward the upper end of the seal ramp surface;
- and
- (c) a seal energizing device for urging the seal element toward the upper end of the seal ramp surface.
