Zusammenfassung:	A decoupling element for a fuel-injection device has a low-noise and pivotable construction. The fuel-injection device includes at least a fuel injector and a receiving bore in a cylinder head for the fuel injector as well as the decoupling element between a valve housing of the fuel injector and a wall of the receiving bore. The decoupling element is in the form of a ring, in particular a closed ring, which has a lower end face that sits on a shoulder of the receiving bore, and which has an upper end face that rises conically from radially outside toward radially inside and is in intimate contact with a spherically curved shoulder area of the valve housing of the fuel injector. The fuel-injection device is particularly suitable for the direct injection of fuel into a combustion chamber of a mixture-compressing combustion engine having externally supplied ignition.
