A solenoid valve includes a magnet armature, which is operatively connected to a sealing element of the solenoid valve in order to move the latter, and an armature opposing piece which is arranged at the end of the magnet armature. An intermediate element, which can be placed in supporting contact with the armature opposing piece, is mounted in an axially movable fashion in a guide recess in the magnet armature. A driver assistant device includes the above-described solenoid valve.
