摘要： A leaf seal arrangement is provided in which within a housing there are edge portions to inter associate with non parallel chamfer edges in leaf seal elements. In such circumstances, deflection of the leaf seal elements in an outward direction or inward direction relative to a rotating shaft creates variation in a control gap X, XX between the edges and the chamfer edge. Such increase or decrease in the control gap X, XX adjusts the aerodynamic radial force that is presented to the leaf seal elements whereby those elements can be more accurately maintained at a desired leaf position for optimizing leakage whilst achieving better wear resistance performance.

摘要： An assembly, for example in a gas turbine engine, includes a rotatable component supported by a bearing in a support structure. A sealing arrangement includes a non-rotating sealing ring which makes sealing contact with sealing features on the rotatable component. The non-rotating sealing ring is radially displaceable with respect to the support structure by means of ribs which engage axially facing support faces of the support structure. The non-rotating sealing ring is radially located by an outer, non-rotating, race of the bearing, by means of a locating surface on a locating body of the non-rotating sealing ring. As a result of this arrangement, the running clearance at the sealing arrangement can be maintained, despite radial displacement of the rotatable component with respect to the support structure, and despite thermal and mechanical deflections of the support structure.
