Abstract

A sealing assembly comprising two abutting components and a sealing profile produced from an elastomeric material, which bridges the gap between the two components to form a seal. The components are configured in particular as sections which are assembled into a tubular tunnel thus forming transverse and longitudinal joints. There is also a sealing profile being located in turn in each recess, thus forming a cornered sealing framework. There is also a lubricant for the contact surfaces between each component and the sealing profile, in particular for the contact surfaces between two sealing profiles. The sealing assembly has at least one sealing profile that has at least two protrusions in the vicinity of the contact surfaces. The protrusions form a sealed chamber, in which the lubricant is contained.
