Abstract

An injection valve (1) comprising a valve assembly (2) and an electro-magnetic actuator unit (19) is disclosed. The valve assembly (2) comprises a valve body (4) with a cavity (9), a valve needle (11) axially moveable in the cavity (9) and a calibration spring (18) for axially biasing the valve needle (11) towards a closing position. The injection valve (1) also comprises a further spring element (27) being arranged in parallel to the calibration spring (18) and preloading a magnetic ring element (28). The magnetic ring element (28) is axially movable in the cavity (9) between a first position, in which a top side (38) of the magnetic ring element (28) is axially spaced apart from the pole piece (25) and an underside (36) of the magnetic ring element (28) is in contact with the valve needle (11), and a second position, in which a top side (38) of the magnetic ring element (28), opposite of the underside (36), is in contact with the pole piece (25).
