Abstract
A sealing arrangement which comprises at least two abutting components that form a gap therebetween and a seal that sealingly bridges the gap. The inventive sealing arrangement is characterized in that the seal entirely consists of a matrix or is provided with a matrix representing a composite system. The matrix is combined with a base body and is a pasty mixture comprising a water-soluble material. A lubricant and a swelling agent which can be activated by means of water as well as optionally additional additives are mixed into the material. In an advantageous embodiment, the matrix is introduced into the chamber. The wall of the chamber is configured in the form of a web that can be torn out. The web is removed before assembly. The base body consisting of an elastomeric material is provided with channels and grooves which extend in an extruded-like manner.
