Abstract

The invention relates to a decoupling element for a fuel injection device that is particularly characterized by a low noise design. The fuel injection device comprises at least one fuel injection valve (1) a receiving bore (20) in a cylinder head (9) for the fuel injection valve (1) and the decoupling element between a valve housing (22) of the fuel injection valve (1) and a wall of the receiving bore (20). The decoupling element is designed as a decoupling system comprising a spring ring (30) and a conical washer (31). The fuel injection device is particularly suitable for the direct injection of fuel into a combustion chamber of a mixture compressing externally ignited combustion engine.
