Abstract
A sealing arrangement for sealing a gap between two components which can move rotationally with respect to one another about a common axis of rotation, having a brush seal on a first component which interacts with a sealing surface of the second component. The sealing surface is conical in form, with at least one component being axially displaceable and adjustable with respect to the other component in order to reduce the gap between the brush seal and the second component.

A sealing arrangement for sealing a gap between two components which can move rotationally with respect to one another about a common axis of rotation, having a brush seal which is arranged fixedly in a first component and interacts with a sealing surface of the second component, wherein the sealing surface is conical in form, with at least one of the first and second components being axially displaceable and adjustable with respect to the other component.
A method of sealing a gap between two components which are rotatable relative to one another about a common axis of rotation, comprising the steps of:
- providing a brush seal fixed to a first one of the two components, wherein the brush inner diameter is between a minimum diameter and a maximum diameter of a conical portion of a second one of the components;
- and
- axially displacing the first component along the common axis of rotation until a distance between the inner diameter of the brush seal and the conical portion of the second component is reduced to a desired distance.
