COMPONENT OPERATION / Pump Device Link Mechanism The movement of pilot piston (22) is transmitted through pin (21) to lever 1 (18). Lever 1 (18) is turned about pin (19), which is fixed to the axial plug. The movement of pilot piston (11) is transmitted through pin (12) to lever 2 (4). Lever 2 (4) is turned about pin (5), which is fixed to the hous- ing. Pin (7) is attached to feedback lever (13). Both ends of pin (7) are inserted into holes (23, 8) on lever 1 (18) and lever 2 (4). Therefore, when lever 1 (18) or lever 2 (4) turns, pin (7) contacts the hole of the turned lever. Feedback lever (13) turns about pin (14) at- tached to servo piston (15).
In addition, when servo piston (15) moves, feed- back lever (13) is moved through pin (14). At this time, as neither lever 1 (18) nor lever 2 (4) move, feedback lever (13) turns about pin (7).
