Abstract: A solenoid valve having a valve disc on a movable armature that is subjected to a restoring spring and a magnet coil. The magnet coil has a pick-up winding with a high-electrical capacity for opening and closing the valve and a holding winding whose capacity is such that it can hold the valve disc in the position in which it is lifted off of the valve seat when the valve is opened or on the valve seat when the valve is closed. A capacitor can be charged with a system voltage that is applied and can be momentarily connected to the pick-up winding in order to open or close the magnetic valve is also provided.
