Abstract
A double-armature solenoid valve may include an adjustable first armature and an adjustable second armature arranged axially opposite each other along a common adjustment axis, and a coil mechanism configured to provide a magnetic flux. The valve may also include a first restoring spring, a second restoring spring, an inlet opening arranged on an axial side of the first armature opposite the second armature, and an outlet opening arranged on an axial side of the second armature opposite the first armature. The inlet opening and the outlet opening may be connected via a fluid duct. The first armature and the second armature may respectively have a different closing time such that when an energization of the coil mechanism is at least one of interrupted and reduced the inlet opening is closable more quickly via the first armature than the outlet opening via the second armature.
