An electromagnetically actuated valve (1) has a core (5), a solenoid coil (8) and an armature that can be acted upon by the solenoid coil (8) in a stroke direction in opposition to a restoring spring (27), and a valve needle (13). The valve needle (13) is fixedly joined both to the armature (11) as well as to a valve-closure member, which cooperates with a fixed valve seat, and constitutes a movable valve element. On the valve needle (13), between the armature (11) and the valve-closure member, an auxiliary body (30) is arranged, which is movable relative to the valve needle (13). The valve needle (13) is designed as having a driving arrangement (34) such that, in response to a motion of the auxiliary body (30) in the stroke direction, the valve needle (13) can be accelerated in the same direction by energy transfer, and a rapid opening of the valve is realized.
