Drive swash plate movement and vary pump output displacement
Joined to the swash plate, the servo piston makes linear reciprocating strokes actuated by pilot pressure oil to adjust how much the swash plate tilts:
Greater tilt angle increases pump displacement and boosts outgoing flow.
Reduced tilt angle decreases pump displacement and cuts outgoing flow.
Enable load sensing and power modulation
Based on pressure feedback within the system, it autonomously modulates swash plate angle to deliver total power and negative flow control, preventing engine stall under excavation loads.
Achieve steady displacement through positional feedback
A feedback linkage transfers the servo piston’s position to the control spool, constructing closed‑loop regulation that quickly locks the flow at the target rate.
