DECOUPLING ELEMENT FOR A FUEL INJECTION DEVICE

摘要

The decoupling element for a fuel injection device according to the invention is characterized in particular in that a low noise design is implemented. The fuel injection device includes at least one fuel injector and a receiving borehole 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 borehole. The decoupling element is a decoupling system made up of a contoured spring seat on a shoulder of the receiving borehole and a spring washer resting on the shoulder. The fuel injection device is suited in particular for direct injection of fuel into a combustion chamber of a mixture-compressing spark-ignition internal combustion engines.
