德國GSR二位二通電磁閥的工作原理
GSR電磁閥里有密閉的腔，在不同位置開有通孔，每個孔連接不同的油管，腔中間是活塞，兩面是兩塊電磁鐵，哪面的磁鐵線圈通電閥體就會被吸引到哪邊，通過控制閥體的移動來開啟或關閉不同的排油孔，而進油孔是常開的，液壓油就會進入不同的排油管，然后通過油的壓力來推動油缸的活塞，活塞又帶動活塞桿，活塞桿帶動機械裝置。這樣通過控制電磁鐵的電流通斷就控制了機械運動。
GSR電磁閥常閉型：通電時，電磁線圈產生的電磁力打開先導孔，上腔室的壓力迅速下降，在活塞/密封件附件形成上低下高的壓差，推動活塞/密封件從閥座上提起，閥門開啟；斷電時，彈簧力關閉先導孔，閥門入口壓力由旁通孔迅速進入上腔室，在活塞/密封件附件形成上高下底的壓差，推動活塞/密封件向下移動壓在閥座上，閥門關閉。
GSR電磁閥常開型：動作方向與常閉型相反。
