Device for injecting fuel into a combustion chamber

The device has multiple jet nozzles (8) arranged parallel to each other and provided with two jet channels (6, 7) for production of fuel jets that are partly collided one on the other in a percussion zone (S). The jet nozzles form a fan nozzle for production of a fan beam (9) by the jet channels, where expansion of the fan beam in a fan level is larger than in a transverse direction to the fan level. A closure element is provided for closing a fuel supply. The jet channels are distributed on a peripheral surface of a nozzle body and formed as circular channels.
