Abstract

A suspension for fuel injection systems is used for connecting a fuel injector to a fuel-carrying component. A connecting body having a receiving space is provided for this purpose. The connecting body has an opening, via which a fuel fitting of the fuel injector is insertible at least partially into the receiving space of the connecting body. Furthermore, an annular element and an elastically deformable element are provided. Fuel fitting is supported via the annular element and the elastically deformable element along an axis of the receiving space of the connecting body. A fuel injection system having such a suspension is also indicated. The suspension allows for a soft coupling of the fuel injector to the fuel-carrying component at a desired target stiffness.
