The electromagnetic valve has a valve housing with a through bore (13). It has a sliding valve element (6) and two electromagnets (2) with an armature (23). The sliding element is pulled into an end position when an electromagnet is stimulated and it is held by the residual remanence when the stimulation voltage is switched off. The bore and sliding element may be coated with a hard material and the armature has two parts (24,25) made of weakly magnetic material with different saturation magnetization levels. The higher level part (25) is associated with the sliding element so that their end surfaces are arranged facing each other. |
