Abstract
The invention relates to a brush seal 1 with bristles 3 arranged at an angle, for sealing a rotor (2) against a stator. The brush seal (1) has a support plate (9) with a longitudinal section (10) and a support section (11). The brush seal (1) also has bristles (3) with shaft sections (6) and bristle sections (7) arranged at an angle to the shaft sections (6). The end of the bristle sections (7) run against the sealing area (U) of the rotor (2). A bending clearance (13) is provided between the shaft sections (6) of the bristles (3) and the support plate (9). Between the bristle sections (7) and across the entire length of the support section (11) of the support plate (9) there is a gap (12) which closes if there is differential pressure on opposite sides of the bristles (3).
