Abstract
A hydraulic actuator includes a shock absorber and a control system that is separate from the shock absorber and which generates damping loads for the hydraulic actuator. The control system generates the damping load by using a pair of variable valves, a pair of check valves, an accumulator, a pump/motor and a flow controller. The forces are generated in all four quadrants of compression/rebound and active/passive. A device which recuperates the energy generated by the hydraulic actuator can be incorporated into the hydraulic actuator to generate energy in the form of electrical energy.
