An arrangement for the selective introduction of fuel and/or water into a combustion chamber, in particular the combustion chamber of a gas turbine, comprises valve means, by which a fuel feed line (18) for the fuel and a water feed line (19) for the water can be selectively connected to a common combustion-chamber feed line (17) leading to the combustion chamber, or the fuel feed line (18) and the water feed line (19) can be connected to one another for flushing the feed-line system, or the fuel feed line (18) and the water feed line (19) can be shut off individually. In such an arrangement, the number of movable parts is drastically reduced owing to the fact that the valve means comprise a combination valve (12), which can be shifted into at least five different valve positions, in which case only the fuel feed line (18) is connected to the combustion-chamber feed line (17) in the first valve position, only the water feed line (19) is connected to the combustion-chamber feed line (17) in the second valve position, the fuel feed line (18) and the water feed line (19) are connected simultaneously to the combustion-chamber feed line (17) in the third valve position, the fuel feed line (18) and the water feed line (19) are connected to one another and are separated from the combustion-chamber feed line (17) in the fourth valve position, and the fuel feed line (18) and the water feed line (19) are shut off individually in the fifth valve position.
