Injection valve for injecting a fluid

The valve has a needle-like injection valve element (1) releasing or closing an injection opening. A magnet actuator (2) includes an armature (5) i.e. exchange armature, which is movable against resilient force of a spring (6) e.g. helical compression spring, in a direction of an inner pole (4) during feeding current to a coil (3). The spring is arranged on a side of the armature, which faces away from the pole. The armature includes an armature plate (5.1) and an armature pin (5.2), which is hydraulically coupled with the valve element by control volumes (7) i.e. hydraulic coupler volumes.
