Abstract:
A decoupling element is described for a fuel injection device which is characterized in particular by a low-noise design. The fuel injection device includes at least one fuel injector, a receiving bore in a cylinder head for the fuel injector, and the decoupling element between a valve housing of the fuel injector and a wall of the receiving bore. The decoupling element is designed as a decoupling system having a spring ring and a conical washer. The fuel injection device is suitable for injecting fuel into a combustion chamber of a mixture-compressing spark-ignition internal combustion engine in particular.
