摘要

A device for a combustion chamber of a gas turbine for controlling the intake of gas into the combustion zone of the combustion chamber. The device includes a control element that is arranged outside the combustion chamber. This control element has a first covering for at least a first inlet to the combustion zone and is displaceable in relation to the combustion chamber. There is also a support for the control element that is connected to the cover. The cover is displaceable relative to the combustion chamber and a support ( 16 ) for the control element ( 12, 12' ) is connected to the cover. The support ( 16 ) is accommodated in a structure ( 4 ) at a rear of the combustion chamber.
