Fuel injection valve

DRIVE May 7, 2003
Source
The fuel injection valve has a solenoid-operated valve needle (3) with a shut-off component (4) formed at the injection end. A swirl element (34) reaches through the valve shut-off component and is installed on the inlet side face (39) of the valve seat (5). The valve needle and/or shut-off component has a taper (37) in the region of the swirl element and reduces the radial extent of the valve needle. The taper extends in the axial direction at least between the sealing seat and inlet side end face (38) of the swirl element.
