Abstract:
A valve assembly for an injection valve is disclosed. The valve assembly includes a valve body having a cavity with a fluid inlet portion and a fluid outlet portion, a valve needle, an armature which is able to slide on the valve needle, and a disc element positioned to limit axial displaceability of the armature relative to the valve needle. The disc element includes a plurality of passages extending in axial direction through a disc-shaped part of the disc element. The passages provide a first flow resistance for a fluid passing in a direction away from the fluid outlet passage and a second flow resistance in a direction towards the fluid outlet passage, wherein the second flow resistance is larger than the first flow resistance.
