Abstract: An injection nozzle (10), especially for injecting liquid fuel, preferably crude oil, into the combustion chamber of a gas turbine, includes an inner chamber (16) which extends along a nozzle axis (19), conically tapers to a concentric nozzle orifice (17), and to which the medium which is to be injected is fed from outside through a plurality of inlet ports (18) which are arranged in a distributed manner around the nozzle axis (19). The inlet ports (18) are oriented perpendicularly to the nozzle axis (19) and each lead tangentially into the inner chamber (16). With such an injection nozzle, an improved spray cone is achieved by the fact that a pin (14), which extends in the axial direction, is concentrically arranged in the inner chamber (16) and passes through the region of the mouths of the inlet ports (18) and extends right into the nozzle orifice (17).
