Valve assembly for an injection valve and injection valve

A valve assembly (11) for an injection valve (100) comprises a valve body (14) including a central longitudinal axis (L), wherein the valve body (14) comprises a cavity (18). Furthermore the valve assembly (11) comprises a valve needle (20) axially moveable in the cavity (18) and preventing a fluid flow out of an injection nozzle in a closing position and enabling the fluid flow out of the injection nozzle apart from the closing position. The valve assembly (11) comprises an electro-magnetic actuator unit (36) being designed to actuate the valve needle (20). The electro-magnetic actuator unit comprises a coil (38) and a core, wherein the core comprises at least a pole piece (12). Additionally the actuator unit (36) comprises an armature (22) axially moveable in the cavity (18) between a first position and a second position. In the case the armature (22) is in the first position, the armature (22) and the pole piece (12) abut. In the case the armature (22) is in the second position, there is a given maximum gap between the pole piece (12) and the armature (22). Furthermore the valve assembly (11) comprises a permanent magnet (48) axially extending at least partly along the extension of the maximum gap, wherein the permanent magnet (48) is arranged radially outwards relative to the armature (22).
