Nozzle device for adding gaseous fuel to a combustor of a gas turbine assembly, comprising - a nozzle main body with nozzle openings for injecting the fuel into the combustor, and - a nozzle holder with at least one fuel line for flow connection between a distributor fuel line of a fuel distributor and the nozzle main body, wherein the fuel line is aligned at least in sections along, and in particular symmetrically to, a central longitudinal axis, and with a throttle element arranged downstream of the distributor fuel line, in particular at the upstream end of the fuel line, for throttling the fuel flow to a predetermined target amount, wherein - the throttle element comprises at least two stages (S1, S2, S3) arranged in series in terms of flow, wherein each stage (S1, S2, S3) has at least one line section (8, 9, 10) which is aligned along a central longitudinal axis (M1, M2, M3) and has a flow cross section, wherein in each case, there is one expansion chamber (11, 12) arranged between the stages (S1, S2, S3), the flow cross section of which is greater than the flow cross section of the stage (S1, S2) arranged upstream thereof, characterized in that - an axial extent of the line sections (8, 9, 10) is less than a diameter (Ds) of the fuel line downstream of the throttle element, and - the line section (8, 9, 10) of at least one stage (S1, S2, S3) is arranged with its central longitudinal axis (M1, M2, M3) radially offset from the central longitudinal axis (M1, M2, M3) of at least one other stage (S1, S2, S3) and/or from the central longitudinal axis of the fuel line downstream of the throttle element. - a nozzle main body with nozzle openings for injecting the fuel into the combustor, and - a nozzle holder with at least one fuel line for flow connection between a distributor fuel line of a fuel distributor and the nozzle main body, wherein the fuel line is aligned at least in sections along, and in particular symmetrically to, a central longitudinal axis, and with a throttle element arranged downstream of the distributor fuel line, in particular at the upstream end of the fuel line, for throttling the fuel flow to a predetermined target amount, wherein - the throttle element comprises at least two stages (S1, S2, S3) arranged in series in terms of flow, wherein each stage (S1, S2, S3) has at least one line section (8, 9, 10) which is aligned along a central longitudinal axis (M1, M2, M3) and has a flow cross section, wherein in each case, there is one expansion chamber (11, 12) arranged between the stages (S1, S2, S3), the flow cross section of which is greater than the flow cross section of the stage (S1, S2) arranged upstream thereof, characterized in that - an axial extent of the line sections (8, 9, 10) is less than a diameter (Ds) of the fuel line downstream of the throttle element, and - the line section (8, 9, 10) of at least one stage (S1, S2, S3) is arranged with its central longitudinal axis (M1, M2, M3) radially offset from the central longitudinal axis (M1, M2, M3) of at least one other stage (S1, S2, S3) and/or from the central longitudinal axis of the fuel line downstream of the throttle element. - an axial extent of the line sections (8, 9, 10) is less than a diameter (Ds) of the fuel line downstream of the throttle element, and - the line section (8, 9, 10) of at least one stage (S1, S2, S3) is arranged with its central longitudinal axis (M1, M2, M3) radially offset from the central longitudinal axis (M1, M2, M3) of at least one other stage (S1, S2, S3) and/or from the central longitudinal axis of the fuel line downstream of the throttle element.
