Fuel nozzle body

A fuel nozzle body comprising:

• a rearward end and a forward end, comprising an outer tube, which extends from the rearward end to the forward end and has radial openings for a first fuel in a region of the forward end, and an inner tube, which is arranged concentrically with respect to the outer tube and which opens in the region of the forward end into a nozzle head, which has additional openings for a second fuel,
• wherein, in the region of the forward end, the inner tube is guided in the outer tube by two fits, which are arranged axially between the radial openings and the additional openings,
• wherein a first fit of the two fits comprises a leakage seal between a first surface feature of the inner tube and a first surface feature on the outer tube encircling the first surface feature of the inner tube,
• wherein a second fit of the two fits comprises a second surface feature of the inner tube and a second surface feature on the outer tube encircling the second surface feature of the inner tube, wherein the second surface feature of the inner tube comprises at least one interruption, and
• wherein the first fit is closer to the radial openings than the second fit.
