Beschreibung
Zusammenfassung:	A damper (100) for reducing the pulsations in a combustion chamber (200) of a gas turbine, wherein the damper (100) comprises: a resonator cavity (110) with an inlet (104) and a neck tube (120) in flow communication with the interior of the combustion chamber (200) and resonator cavity (110), and a compensation assembly (130) pivotably connected with the neck tube (120)and is inserted between the resonator cavity (110) and the combustion chamber (200) to permit relative rotation between the combustion chamber (200) and the resonator cavity (110).
