Abstract: A brush seal for sealing a leakage gap in an axial flow path between a relatively higher fluid pressure region and a relatively lower fluid pressure region. The brush seal may comprise an outer housing and an inner housing located at least partially within and configured for radial displacement relative to the outer housing. The outer housing may comprise a first downstream outer contact member comprising a first upstream facing outer contact surface configured along a first radial contact line. The outer housing may comprise a second downstream outer contact member comprising a second upstream facing outer contact surface configured, and radially spaced from the first upstream facing outer contact surface, along the first radial contact line to define a downstream outer chamber opening of a downstream outer housing chamber therebetween.

Abstract: A sealing arrangement (30) for providing sealing between a first structure (10), e.g. a rotor shaft, and a second structure (15), e.g. a portion of a casing, of an engine, and between first (HP) and second (LP) pressure regions located between the first (10) and second (15) structures, the first pressure region (HP) being at a relatively higher pressure than the second pressure region (LP), and the first structure (10) being moveable relative to the second structure (15) along an axis, wherein the sealing arrangement (30) comprises: a sealing member (20), e.g.
