    摘要: A combustion chamber (10) for a gas turbine engine (1) comprises:
    - an inner wall (22) delimiting an inner volume (V) of the combustion chamber (10), through which combustion gas flow from a burner (2) to a gas turbine (3) of the gas turbine engine (1),
    - a plurality of dampening cavities (30) for the dampening of thermo-acoustic vibrations in the combustion gas, each dampening cavity (30) communicating with the inner volume (V) through at least a dampening hole (40) on the inner wall (22),
    - at least a cooling passage (50) for a cooling medium flowing outside the inner volume (V) in thermal contact with the inner wall (22), each dampening cavity (30) comprising at least a purging hole (60) communicating with the cooling passage (50) for purging a portion of the cooling medium through the dampening cavities (30) to the inner volume (V).
