Squeeze-film damper arrangement
Abstract:
A squeeze-film damper arrangement comprising: concentric inner and outer components defining an annular gap there between for accommodating radial motion of the inner component within the outer component; and a fluid filling the annular gap around the outside of the inner component for damping said radial motion of the inner component, the fluid being axially contained between spaced-apart, radially-compliant first and second face-seals provided between the inner and outer components; wherein the first face-seal is provided between the opposing faces of a first pair of radially overlapping circumferential sealing elements associated with the inner and outer components respectively, a first one of the circumferential sealing elements in said pair being mounted for axial movement relative to the associated inner or outer component and being axially biased against the second of said circumferential sealing elements in said pair to form the first face-seal.
