Alter swash plate inclination and adjust pump displacement Coupled to the swash plate, the servo piston undergoes linear back‑and‑forth movement under pilot hydraulic oil pressure to change the swash plate tilt: Expanded swash plate angle leads to higher pump displacement and stronger output flow. Contracted swash plate angle leads to lower pump displacement and weaker output flow.

Operate load sensing and power control logic It automatically calibrates swash plate angle using system pressure feedback, implementing total power and negative flow control to avoid engine stall and fit excavation load profiles.

Stabilize displacement with position feedback mechanism The feedback linkage mounted on the servo piston transmits position signals to the control spool. Closed‑loop adjustment ensures fast stabilization at the intended flow.
