Abstract (en)
A valve assembly (3) comprising a valve body (4) with a cavity (9) having a fluid inlet portion (5) and a fluid outlet portion (7), a valve needle (11) and an armature (23) is disclosed. The armature (23) has a plurality of flow holes (36) extending in an axial direction from an upper side (33) of the armature (23) to a lower side (35), the flow holes (36) permitting fuel to pass through the armature (23) . Inlets (37) of the flow holes (36) are at a distance R<sub>1</sub>from the central longitudinal axis L, wherein R<sub>1</sub>is larger than the radius r<sub>P</sub>of a central opening (28) in an element of the valve assembly (3) adjacent to the upper side (33) of the armature (23) . Outlets (39) of the flow holes (36) are at a distance R<sub>2</sub>from the central longitudinal axis L, wherein R<sub>2</sub>is smaller than the radius r<sub>H</sub>of a disc-shaped element (40) arranged in an axial region of the valve needle (11) adjacent to the lower side of the armature (23) . A fuel injection valve (1) comprising the valve assembly is also disclosed.
