Fuel injector with a damping element and method for manufacturing a fuel injector

The proposed fuel injector comprises a fuel passage way in which a harmonic damper 25 is arranged. The harmonic damper dampens the noise and vibration of the fuel injector. The harmonic damper is fixed to the inlet tube of the fuel injector. The harmonic damper has a cylindrical shape with a central bore. An outer face of the harmonic damper is adjacent to an inner face of the inlet tube. The harmonic damper may be made of plastics or metal.
