| 摘要 |
<p>The invention relates to a magnetic valve, comprising a mobile armature on which a valve disc that is subjected to the action of a return spring is mounted; and a magnet coil. Said magnet coil has a pick-up winding (9.1) with a high electrical capacity, for (a) opening or (b) closing the valve and a holding winding (9.2) whose capacity is such that it can hold the valve disc (3) in the position in which it is lifted off of the valve seat (1.1) when (a) the valve is opened or (b) when the valve is closed, holding the valve disc in the position in which it is in contact with the valve seat. A capacitor (C) which can be charged with a system voltage that is applied and can be momentarily connected to the pick up winding (9.1) in order to (a) open or (b) close the magnetic valve is also provided.</p> |
