Patent number: 11703127Abstract: A seal assembly includes: a seal element; a part to be sealed; and a measuring arrangement for monitoring an aging of the seal element. The seal element is held on the part so as to provide a contact stress between the seal element and the part. The seal element has a contact face with which the seal element bears against the part. At least one measuring component of the measuring arrangement is integrated in each case into the seal element and into the part. The contact face of the seal element has a surface geometry with depressions.Type: GrantFiled: January 9, 2020Date of Patent: July 18, 2023Assignee: CARL FREUDENBERG KGInventors: Olaf Nahrwold, Stefan Sindlinger, Boris Traber, Tanja Claus, Thomas Kramer, Frank Lauer, Rainer Kreiselmaier, Guido Hohmann, Christoph Naumann
