回转接头安装在上壳体中间。 此部件用于将液压油从上部壳体的输入管路输送到下部壳体中的液压油缸。 回转接头允许作业机具旋转 360 度,而不会损坏油缸管路。 由于转子 (3) 没有在定子 (2) 上固定到位,转子可以在定子轴上自由旋转。 这将允许上壳体在下壳体旋转时保持静止不动。

油可以在端口 (4) 或端口 (5) 处进入回转接头。 操作员选择的功能方向(打开或关闭)决定油的进入点。 当油进入端口 (5) 时,油沿着定子 (2) 中的油道流动,并从端口 (6) 流出到油缸。 随后,回油将从油缸流回端口 (1)。 油流过定子 (2) 中的油道,并从端口 (4) 流到液压油箱。

由于定子 (2) 用螺栓固定到上壳体上,定子保持固定不动。 转子 (3) 随下壳体旋转。
