Abstract
A seal arrangement has two machine parts movable toward one another along or about a movement axis. One of the two machine parts forms a seal holding structure and the other forms a sealing surface. A sealing device between the two machine parts is arranged on or in the seal holding structure, wherein the sealing device includes a sealing element and a pre-tensioning element which is separate from the sealing element and by means of which the sealing element is tensioned in the radial direction against the sealing surface of the respectively other machine part. The sealing element is formed by an elastically deformable sealing film. On the sealing film side, the pre-tensioning element forms an embossed structure which presses into the sealing film where the sealing film bears against the sealing surface with a contact pressure progression which corresponds to the embossed structure of the pre-tensioning element.
