<p>A brush seal 51 adapted to restrict a fluid flow through a gap 65 between a first component 53 and a second component 63, comprising: a body 55,57; a brush pack 61 secured to said body; and a passage 67 through said body for introducing a cooling flow C to said gap. The passage 67 has a first end that is exposed to the gap 65 and a second end that is not exposed to the gap 65. The passage discharges a cooling flow C to said brush seal 51, the cooling flow C being discrete from the fluid flow.</p> |
