Abstract
A description is given of a damping arrangement for reducing resonant vibrations in a combustion chamber (), with a combustion-chamber wall (), which is of double-walled design and, with an outer wall-surface part () and an inner wall-surface part () facing the combustion chamber (), gastightly encloses an intermediate space (), into which cooling air can be fed for purposes of convective cooling of the combustion-chamber wall (). The invention is distinguished by the fact that at least one third wall-surface part () is provided, which, with the outer wall-surface part (), encloses a gastight volume (), and that the gastight volume () is connected gastightly to the combustion chamber () by at least one connecting line ().
