Abstract
An arrangement of a shaft with a slip-ring seal mounted thereon is disclosed. The slip-ring seal () comprises a pair of cooperating slip rings (), the sealing faces of which define a sealing gap () between them. One of the slip rings is mounted on the shaft () with torque transmission from a drive element () mounted on the shaft, whilst the other slip ring is provided for fixed mounting on a stationary component. The arrangement is characterised in that the drive element () comprises a tubular drive housing (), extending over the external circumference of the slip ring () with a radial gap () and a passage () for introduction of a flow medium is provided, opening out at one end in a chamber (A), defined by the drive housing (), which drains out through the radial gap (), whereby the radial gap forms a flow path for the flow medium which terminates at or near the sealing gap ().
