    Abstract: A ride control system includes a shock absorber having a movable piston that divides the shock absorber into a lower and an upper volume and a center check valve that allows fluid to flow from the upper to the lower volume. A back pressure actuator provides a selectable back pressure to the lower volume. Three two way valves and a check valve allow the lower and upper volumes to be selectively coupled to either the selectable back pressure or a shock absorber fluid reservoir to provide passive, semi-active, or active ride control. The back pressure actuator pressurizes a hydraulic accumulator when shock absorber fluid flows into the back pressure actuator to provide energy recovery.

    Abstract: Micro-hydraulic supply and storage units capable of recovering waste energy and storing energy for later use, such as for operating hydraulic valve actuation and high pressure fuel injection systems. The system includes a sump, a pump motor, an accumulator and a supply rail. Valving is provided to couple the outlet of the pump motor to the accumulator to fill the accumulator with what otherwise would be waste energy, such as when a vehicle is using its engine for braking, directing the output of the pump motor to a supply rail to maintain the pressure in the supply rail, and directing the output of the pump to a sump. The valving also allows directing an outlet of the accumulator to an inlet of the pump motor for recover of the energy in the accumulator. Other aspects of the invention are disclosed.
