ABSTRACT:
A hydraulic cylinder assembly to be used in an actively controlled suspension system includes a built-in pressure accumulator. The pressure accumulator employed in the hydraulic cylinder assembly has a reciprocally movable free piston for dividing a fluid chamber and a pneumatic chamber. The free piston thrustingly moves for establishing pressure balance between the fluid chamber and the pneumatic chamber and, in turn, for establishing pressure balance between the fluid chamber and an associated pressure chamber in the hydraulic cylinder so as to accumulate pressure while the fluid in the associated pressure chamber is compressed and to supply the pressure when the associated pressure chamber expands while absorbing vibration energy exerted between a vehicle body and a suspension member.
