Abstract
A seal arrangement suitable for sealing between two coaxially mounted, axially restrained, radially spaced apart and relatively rotatable members comprises two concentric, ring-shaped seal elements having adjacent sealing faces. The seal elements are mounted on the respective members by a spline and groove arrangement which permits radial growth or shrinkage of the relatively rotatable members due to their thermal expansion or contraction without such growth or shrinkage being transferred to the seal elements. The arrangement insures that the gap between the sealing faces of the seal elements remains substantially constant during thermal variations.
