Abstract
A sealing arrangement for sealing a gap (11) between two concentric machine elements which can relatively move with respect to each other, the first machine element (3) having a smooth contact surface (5) and the second machine element (4) having a profiled section (6) which faces the contact surface (5) of the first machine element (3), accommodates a sealing ring (2). The profiled section (6) is bounded by a first flank (8) and a second flank (9). The sealing ring has a curved peripheral surface (7) and a radial surface (13), either of which may be completely exposed to the high pressure side. A sealing edge (10) of the sealing ring (2) is formed by the line of intersection of a conical surface (14) and the curved peripheral surface (7). The conical surface (14) merges into the radial surface (13). The sealing ring of the invention has a defined pressing distribution and, if the curved peripheral surface (7) faces the high-pressure side, the whole surface of the sealing ring is pressed positively against the second flank (9) by a pressurized medium.
