Abstract (en)
[origin: US6296199B1] A fuel-injection valve, in particular, a high-pressure injection valve, for injecting fuel directly into a combustion chamber of a mixture-compressing internal combustion engine with externally supplied ignition is distinguished by the fact that a guide and seating area formed by three disc-shaped elements is provided at a downstream end of the valve. A swirl element is embedded between a guide element and a valve seat element. The guide element is used to guide a valve needle which passes through it and can move in the axial direction, while a valve closing segment of the valve interacts with a valve seat surface of the valve seat element. The swirl element has an inner opening area with multiple swirl channels. The three disc-shaped elements are permanently connected to each other, forming a positive-locking joint.
