Abstract:
The hold-down device for a fuel injection device is distinguished by a particularly simple design that nonetheless permits a very effective holding down of a fuel injection valve. The fuel injection device includes at least one fuel injection valve, a receptacle bore for the fuel injection valve, and a connecting fitting of a fuel distributor line, the hold-down device being clamped between a shoulder of the fuel injection valve and an end surface of the connecting fitting. The hold-down device has a partially annular base element from which there extends, in a bent-away fashion, an axially flexible hold-down clip that has at least two webs, two oblique segments, and two support segments. The fuel injection valve is particularly suitable for use in fuel injection systems of mixture-compressing externally ignited internal combustion engines.
