6 Operating principle A1 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 X1 X2 X3 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. v X1 X2 6
