Abstract
A brush seal, which may be used in gas or steam turbine rotor applications, includes a packet of bristles attached to a seal housing. A seal member is slideably-attached to the seal housing, has a planar first surface portion parallel to, and slideably in contact with, a first surface of the seal housing, and has a planar second surface portion which is parallel to, and slideably in contact with, a first side of the bristle packet. A mechanical spring is positioned in compression between the seal housing and the seal member.
