Injection valve for controlling a fluid flow, wherein the injection valve extends along a central longitudinal axis (L) and comprises a valve body , an armature element , a pole piece and a calibration spring , wherein the valve body forms a valve cavity and comprises a valve seat and a first and a second opening for allowing the fluid flow through the injection valve , wherein the armature element is arranged axially movable in the cavity and comprises an armature portion , a needle portion and a bore which houses the calibration spring and provides a first contact surface for the calibration spring , wherein the pole piece is arranged at the valve body and provides a second contact surface for the calibration spring , wherein the needle portion is pressed against the valve seat by the calibration spring in a closed position inhibiting the fluid flow through the second opening and wherein the needle portion allows the fluid flow through the second opening in further positions, wherein the first opening extends radially through the valve body with respect to the central longitudinal axis (L) and the second opening extends in axial direction through the valve body with respect to the central longitudinal axis (L) so that the axis of the first opening and the axis of the second opening are arranged at an angle to one another, characterized in that the injection valve comprises a solenoid actuator which attracts the armature element when energized and thereby moves the needle portion away from the closed position in further positions to allow the fluid to flow through the injection valve , the armature element comprises a first guiding protrusion and an second guiding protrusion which are axially spaced from one another with respect to the central longitudinal axis (L) and which contact at least partially an inner surface of the valve body whereby the movement of the armature element is guided by the guiding protrusions and the inner surface of the valve body . wherein the armature element is arranged axially movable in the cavity and comprises an armature portion , a needle portion and a bore which houses the calibration spring and provides a first contact surface for the calibration spring , wherein the pole piece is arranged at the valve body and provides a second contact surface for the calibration spring , wherein the needle portion is pressed against the valve seat by the calibration spring in a closed position inhibiting the fluid flow through the second opening and wherein the needle portion allows the fluid flow through the second opening in further positions, wherein the first opening extends radially through the valve body with respect to the central longitudinal axis (L) and the second opening extends in axial direction through the valve body with respect to the central longitudinal axis (L) so that the axis of the first opening and the axis of the second opening are arranged at an angle to one another, characterized in that the injection valve comprises a solenoid actuator which attracts the armature element when energized and thereby moves the needle portion away from the closed position in further positions to allow the fluid to flow through the injection valve , the armature element comprises a first guiding protrusion and an second guiding protrusion which are axially spaced from one another with respect to the central longitudinal axis (L) and which contact at least partially an inner surface of the valve body whereby the movement of the armature element is guided by the guiding protrusions and the inner surface of the valve body . <EOS>
