Abstract
The invention relates to a magnet valve for actuating a fuel injector, having a magnet core and magnet coil received in the core. A closing spring acts on the magnet armature in the closing direction. An outlet gap for an actuating fluid is formed between a face end of the stop sleeve, oriented toward the magnet armature, and the magnet armature itself. The outlet gap discharges into a hydraulic damping chamber, which is defined by a face end of the magnet armature and by a damping face of the non-magnetic material.
