  "textContent": "The invention refers to a valve needle assembly comprising a valve needle (14) and an electro-magnetic armature (16) coupled to the valve needle (14), the valve needle assembly being suited for use in a valve assembly (10) of an injector unit for injecting fuel into an engine of a vehicle, said valve assembly comprising a valve body (18) with a valve body cavity (20), in which the valve needle assembly is to be inserted, said valve body (18) comprising at least one ring type guiding zone (28) for guiding an axial movement of the valve needle assembly, and the valve needle assembly comprising a corresponding cylindrical guiding zone (30). In accordance with the invention it is provided that sizing means (28,34,36) comprise at least one sizing member (36) neighbouring the cylindrical guiding zone (30) for sizing the diameter of the ring type guiding zone (28) when inserting the valve needle assembly into the valve body cavity (20).",
