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