Abstract

A solenoid valve comprising a magnet armature which is embodied as having multiple parts and has an armature disk and an armature bolt. The magnet armature is guided in a slider. A damping device is provided in order to prevent post-pulse oscillation of the armature after a closing of the solenoid valve. The required short switching times of the solenoid valve can be exactly maintained with a device of this kind. The solenoid valve is designated for use in injection systems with a common rail.
