Abstract

The invention relates to a high temperature-resistant sealing assembly comprising a sealing segment and a component border which is connected to the sealing segment. A flexible sealing element is provided in order to joining the sealing segment and the component border. The invention is characterized in that the flexible sealing element compensates both thermal expansions and relative movements of the component border and the components resting against the sealing segment. The flexible sealing element and the sealing segment are subject to little wear and have a long service life. The invention further relates to a combustion chamber that is equipped with a high temperature-resistant sealing assembly as well as a gas turbine encompassing such a combustion chamber.
