Abstract
A brush seal for sealing between a rotor and a stator of a gas turbine engine includes a housing and a plurality of flexible bristles held within the housing. The bristles protrude from the housing so that a free end of each bristle is able to contact and seal against a seal surface of the rotor. The brush seal further includes a stop member for limiting movement of the free ends of the bristles towards the seal surface of the rotor, in order to reduce wear on the bristles.
