The invention relates to a decoupling element for a fuel injection device, said decoupling element being characterized in that it has a low-noise and pivotable design. The fuel injection device comprises at least one fuel injection valve (1) and a receiving bore (20) in a cylinder head (9) for the fuel injection valve (1) as well as the decoupling element (25) between a valve housing (22) of the fuel injection valve (1) and a wall of the receiving bore (20). The decoupling element (25) has an annular design, in particular in the form of a closed ring, which has a lower end surface (26) that rests on a shoulder (23) of the receiving bore (20) and an upper end face (27) which extends in a conically rising manner from radially outwards to radially inwards and has a bearing contact with a spherically curved shoulder face (21) of the valve housing (22) of the fuel injection valve (1). The fuel injection device is especially suitable for direct injection of fuel into a combustion chamber of a mixture-compressing, spark-ignited internal combustion engine. |
