| 摘要 |
The invention relates to a sliding seal (12) made of a carbon and/or graphite material having a sliding surface. To simplify the manufacturing process without any loss of sealing effect, it is proposed that the sealing surface (18) of the unused sliding seal (12) should have at least one peripheral protrusion (20) that is supportable on a surface (14) to be sealed and serves as the breaking-in aid.
