Rudder stock

3、 Tiller arm Ram Hunting gear Crosshead when the plate or ring is moved in one direction from mid position, oil is drawn from one cylinder and discharged into the other; when the plate or ring is moved in the opposite direction, the suction and discharge of the oil is reversed in direction. The plate

4、 or ring is actuated by a control rod which is attached at its outer end to the hunting gear(隨動機構隨動機構). The transmitter, which is built into the steering wheel console (舵舵 輪控制臺輪控制臺), is located on the bridge and the receiver is mounted on the steering gear. The control box assembly is mounted on the

5、 steering gear. Movement of the bridge transmitter results in electrical imbalance and current flow to the motor in the control box. The motor drives, through a flexible coupling(柔性聯(lián)軸柔性聯(lián)軸 節(jié)節(jié)), a screw shaft, causing it to turn. A screw block on the shaft is moved and in turn moves the floating lever

6、 to which a control rod is attached. The control rod operates the slipper ring or swash plate of the variable delivery pump. A cut-off lever(反饋桿反饋桿) connected to the moving tiller will bring the floating lever pivot(樞軸，交點樞軸，交點) and the lever into line at right angles to the screw shaft axis(軸線軸線). At this point the rudder angle will match the bridge lever angle and the pumping act
