FIELD: machine engineering.
SUBSTANCE: brush seal (9) comprises a housing (4) and a plurality of brushes fixed to the housing (4) of the bristles of the brush (5). The free ends of the bristles (5) are supported with respect to the sealing surface (6) on the rotor (2). On the rotor (2) are provided in the radial direction in front of and behind the sealing surface (6) radially running around the circle relief grooves, so that in the region of the sealing surfaces (6) formed by a jumper, which can locally deform, in particular when tripping casing brush seal surface , so that danger may be minimized, and curvature of the rotor thus threatening attack oscillations along a helical path.
EFFECT: invention relates to a steam turbine system with a brush seal.
