  • the mounting structure may in this case be formed in particular by the internal combustion engine.
  • the attachment structure may be a cylinder head of the internal combustion engine.
  • the holder according to the invention and the fuel injection system according to the invention can be manufactured and sold independently of such a mounting structure, in particular an internal combustion engine.

  • the inner layer, the damping layer and the outer layer may be connected to one another in an adhesive-bonded manner. In operation, relative movements between the innermost layer and the outer layer then occur in the axial direction.

  • the cushioning layer may be bonded to the rigid layers by vulcanization.
  • the damping layer may in this case be advantageously formed from a material based on a rubber.
  • the term rubber is to be understood generally and includes synthetic rubber as well as natural rubber.

  • Multi-layer damping elements may be advantageous in relation to the particular application. Specifically, an embodiment with three metallic layers and two viscoelastic damping layers is possible, which are stacked alternately.
  • a damping element with thin viscoelastic damping layers due to the high material damping allows a substantial reduction of the vibration characteristics and the structure-borne sound transmission, without thereby making the rigid connection too flexible.
  • the stiff position of the fuel distributor on the mounting structure can thereby be substantially maintained, so that the relevant functional requirements are met.
