Beschreibung
Zusammenfassung:	Valve assembly comprising: a valve body with an inlet and an outlet; a valve needle in the valve body preventing fluid flow through the outlet when closed and permitting the flow otherwise; a retaining element connected to the needle, extending radially and remote from the fluid outlet; and an electro-magnetic actuator to actuate the valve needle. The electro-magnetic actuator unit comprises an armature movable relative to the valve body. The armature defines a central axial opening through which the valve needle extends and slides on the valve needle. The retaining element limits the axial displacement of the armature. The armature comprises at least one axial slot arranged adjacent to and connected with the central axial opening, extending through the armature in the axial direction. The retaining element projects beyond the central axial opening and the axial slot projects beyond the retaining element in the radial outward direction.
