摘要： A brush seal is provided for sealing, with minimized leakage, a circumferential gap (S), for example between a rotor (1) and a stator (2) in a gas turbine engine. The brush seal includes a bristle housing (4) rigidly mounted on the stator or the rotor, and bristles (6) having fixed ends securely and durably held in the housing (4) and free ends protruding toward and into the annular gap (S). The housing (4) includes two holder disks (5A, 5B) with an interspace (Z) therebetween, wherein the interspace includes at least one of an axially directed first clamping portion (8) and a radially directed second clamping portion (10), and a widened non-clamping portion (7A, 7B). The fixed ends of the bristles are clampingly held in the first and second clamping portions, while the free ends of the bristles extend generally toward the opposite rotor or stator while being movably supported and guided by the widened non-clamping portion of the interspace (Z). The bristles (6) may extend at a tilt angle in the circumferential direction and may be stitched, woven, or glued together at their fixed ends in order to form a single bristle packet.

摘要： A brush seal (1, 101) seals a circumferential gap (S.sub.1) between two relatively rotatable machine components (2, 102; 3, 103), such as the rotor or a shaft and a stator of a fluid flow machine, such as a gas turbine engine. A plurality of seal bristles (4, 104) are fixed in a bristle holder (5) in an annular shape, and are mounted on the stator (3, 103) so that the free bristle ends (7, 107) extend toward and provide a seal against a seal surface (9, 109) of the rotor (2, 102). Each bristle includes a middle body portion (4A) that is tilted at a first tilt angle (.alpha..sub.1) in the circumferential direction following the rotation direction, and the free bristle end (7, 107) is bent or angled relative to the tilted body portion (4A) so as to extend at a second tilt angle (.alpha..sub.2) which is smaller than the first tilt angle (.alpha..sub.1). Preferably, the first tilt angle (.alpha..sub.1) is in the range from 30.degree. to 60.degree., while the second tilt angle (.alpha..sub.2) is in the range from 0.degree. to 15.degree.. The bristles may further be tilted in an axial direction at an angle (.beta.) relative to a radially extending plane. Since the free bristle ends (7, 107) extend substantially perpendicularly to the seal surface (9, 109), the seal effectiveness and the elastic resiliency of the brush seal are maintained, and the bristles are not damaged, independent of the rotation direction of the rotor.

摘要： A brush seal for sealing a rotor against a housing. The brush seal includes a front panel and a supporting plate attached to the housing wherein a number of bristles are disposed between the front panel and supporting plate. A seal housing that defines a fit surface is formed by cold joining the front panel and supporting plate. The front panel or the supporting plate include a beaded lip for firmly joining the front panel to the supporting plate.
