ABSTRACT:
A valve needle includes a valve needle section which connects the armature section and the valve closing element section, the valve needle section having a solid construction. In order to ensure that the fuel flows in the direction of the valve seat, at least two axial grooves are provided in the armature section. The axial grooves in the armature section are constructed in such a way that the emerging fuel can flow along the outer circumference of the valve needle section in the direction of the valve seat. The valve needle is particularly suitable for injection valves in fuel injection systems of mixture-compression, spark-ignition internal combustion engines.
