Abstract
This invention relates to a seal between two components which two components can move relative to one another. The seal can be used in particular for hydraulic, pneumatic or hydropneumatic systems, whereby at least one elastic seal element interacts with a running surface. Preferably, this seal is used between a piston-shaped part and a cylinder-shaped part. In any case, the running surface, which running surface is mobile relative to the gasket, is provided with depressions. The depressions in the running surface, which running surface interacts with the gasket, form a cross-hatched pattern.
