摘要:
A fuel injection valve, in particular, a high-pressure injection valve, for injecting fuel directly into a combustion chamber of a compressed-mixture internal combustion engine with externally supplied ignition. The fuel injection valve includes a guide and seating area formed by three disc-shaped elements provided at the 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 needle interacts with a valve seat surface of the valve seat element. The swirl element has an inner opening area with multiple swirl channels which are not joined to the outer circumference of the swirl element. The entire opening area extends completely across the axial thickness of the swirl element.
