Abstract

An axial sealing device has a sealing member 36 mounted between a stationary part 23 of a machine and a rotating part 28 of the machine. A static sealing ring 60 is located between a surface 57 of the stationary machine part 23 and a corresponding surface 53 of the sealing member 36. To provide at least partial pressure equalisation on the sealing member 36, this member 36 has one or more steps 53, 54 formed in it and supplied with axial fluid pressure so that axial pressure is exerted on the sealing member 36 in the direction tending to close the sealing gap 50 between a surface 48 of the sealing member 36 and a surface 49 of the rotating machine part 28, an oppositely directed axial pressure acting on the sealing member 36 at the sealing gap 50. <IMAGE>
