Operating principle A1

Cylinder retracting:

The pump displaces fluid from B to A. During

retracting, the effective area is X2. The fluid

of piston chamber X1 flows via the pump

to annulus chamber X2. The differential volume

of piston rod X3 is displaced into

the accumulator.

Cylinder extending:

The pump displaces fluid from A to B. During

extending, the effective area is X1.

The fluid flows from annulus chamber X2 via

the pump into piston chamber X1. The differential

volume of piston rod X3 is displaced from the

accumulator to piston chamber X1. v
