Abstract: The active suspension system includes right and left dampers, a pump, and a control valve system. Each of the right and left dampers includes a damper housing, a piston rod, and a piston that is mounted on the piston rod. The piston is arranged in sliding engagement inside the damper housing such that the piston divides the damper housing into first and second working chambers. The pump includes a pump intake and a pump outlet. The control valve system is connected in fluid communication with the first and second working chambers of the right damper, the first and second working chambers of the left damper, the pump intake, and the pump outlet. The control valve system has several different arrangements of fluid flow paths that provide different working modes for the active suspension system.
