Abstract

The invention relates to a combustion chamber ring (01) with an annular combustion chamber wall (02). To dampen combustion vibrations, a plurality of resonators (11) are arranged on the outside, each enclosing a cavity (12). It is necessary to ensure a connection between the cavities (12) and the combustion chamber by means of a plurality of damping openings (13). A plurality of purge air openings (14) are used to cool the resonators (11), connecting the cavities (12) to a cooling air supply. [0083] The resonators (11) are arranged in resonator rows (05) extending along the central axis. To reduce cooling air consumption and simultaneously ensure effective damping of vibrations, at least three different resonators (11) are provided within each resonator row (05).
