Abstract
A fuel injection device for a combustion chamber of a gas turbine with a liquid-cooled injection nozzle having a coolant tube which surrounds a fuel-conducting tube at a distance and which terminates in an annular chamber in the vicinity of the nozzle exit opening, or which constitutes this annular chamber which directly surrounds the fuel-conducting tube, wherein a separating wall element which surrounds the fuel-conducting tube is provided inside the coolant tube upstream of the annular chamber, viewed in the flow direction of the fuel, which divides the interior of the coolant tube into two chamber segments, wherein the first chamber segment is connected with a feed conduit and the second chamber segment with a removal conduit for the coolant.
