Rexroth配有電子位置反饋器的先導式三位四通伺服換向閥由 2 個主要部件構成:先導閥(1),配有控制控制閥芯和閥套、回位彈簧、控制電磁鐵和感應式位移傳感器;主級(2),配有對中彈簧和位置反饋器
功能說明:當沒有操動控制電磁鐵時,先導閥的控制滑閥在彈簧力作用下處在“Fail-Safe”功能位置中,主級滑閥處在其彈簧對中的中間位置。在集成電子控制器中將設定值與主級控制滑閥的位置實際值進行比較。 如果存在控制偏差,就會驅動控制電磁鐵,以改變磁力的方式對先導滑閥進行調整。 經過控制截面的體積流量使得主控制滑閥移動。 如果將設定值設置為 0 V,則主級的控制滑閥就會在對中彈簧作用下保持在被遮蓋的中間位置。要么在內部通過接口 P,或者在外部通過接口 X 將控制油供應給先導閥。 可以在內部通過接口 T 或者在外部通過接口 Y 回流到油箱。
電源故障:如果發生故障,或者當電纜斷線時,集成式電子控制器就會將控制電磁鐵斷電,先導滑閥進入“Fail-Safe”功能位置,并且將主級的控制油腔卸空。 主級控制滑閥在彈簧作用下進入中間位置。
