Abstract
Abstract An electro mechanic valve device for an ink jet printer comprising at least two valves arranged in a valve housing. Each valve is associated with a magnet core having a winding and a valve pipe having a valve armature and a counter armature. The windings at adjacent magnet cores are arranged alternatingly, a first one at one side of the row of valve pipes and the next one at the opposite side.
