FIELD: engines and pumps.
SUBSTANCE: resonator for pressure oscillations damping in combustion chamber contains container filled with gas, container hole and heating element made with possibility to generate flame. The flame is intended to heat the gas in the container. The heating element is made with the possibility to generate flame, and for quick temperature change of the gas filling the container, and hence quick change of the resonant frequency of the resonator.
EFFECT: invention dampers gas oscillations at different operation modes, and increases productivity of the combustion chamber, using only one resonator instead of several different resonators, each of them is set to different operation modes of the combustion chamber.
