<p>The invention relates to a sealing arrangement (1) for sealing a first space (A) against a second space (B) of a machine arrangement (2), comprising a first carrier element (3) which is fixed at or in a first machine part (4) of the machine arrangement (2) and a second carrier element (5) which is fixed at or in a second machine part (6) of the machine arrangement (2), wherein the second machine part (6) can rotate relatively to the first machine part (3). To obtain a good sealing performance the invention is characterized in that at least one magnet (7) is arranged at the first carrier element (3), wherein a magneto-rheological fluid (8, 9) is arranged at at least a part of the surface of the mag- net (7) and/or at at least a part of the surface of a part (10) of the sealing arrangement (1) in which a magnetic field is induced by the magnet (7), where- in at least a part of the second carrier element (5) is arranged in the proximity of the magneto-rheological fluid (8, 9), wherein a gap (11, 12, 13) is established between the second carrier element (5) and a surface of the magneto-rheological fluid (8, 9) and wherein a ferro fluid (14) is arranged in the gap (11, 12, 13).</p> |
