A valve assembly for an injection valve may comprise a valve body including a central longitudinal axis, the valve body comprising a cavity with a fluid inlet portion and a fluid outlet portion, a valve needle axially movable in the cavity, the valve needle preventing a fluid flow through the fluid outlet portion in a closing position and releasing the fluid flow through the fluid outlet portion in further positions, the valve needle comprising a ring element extending radially and arranged at an axial end of the valve needle facing away from the fluid outlet portion, and an electro-magnetic actuator unit being designed to actuate the valve needle. The electro-magnetic actuator unit comprises an armature axially movable in the cavity. The armature comprises a recess in which the ring element is located, and a protrusion extending radially into the recess. A spring element is arranged in the recess axially between the ring element and the protrusion of the armature. |
