Abstract:
A linear energy harvesting device that includes a housing and a piston that moves at least partially through the housing when it is compressed or extended from a rest position. When the piston moves, hydraulic fluid is pressurized and drives a hydraulic motor. The hydraulic motor drives an electric generator that produces electricity. Both the motor and generator are central to the device housing. Exemplary configurations are disclosed such as monotube, twin-tube, tri-tube and rotary based designs that each incorporates an integrated energy harvesting apparatus. By varying the electrical characteristics on an internal generator, the kinematic characteristics of the energy harvesting apparatus can be dynamically altered. In another mode, the apparatus can be used as an actuator to create linear movement. Applications include vehicle suspension systems (to act as the primary damper component), railcar bogie dampers, or industrial applications such as machinery dampers and wave energy harvesters, and electro-hydraulic actuators.

Claim (Index 11):
A hydraulic assembly for an active suspension system of a vehicle, the hydraulic assembly comprising:\n an inner tube defining an internal volume; a piston slidably received in the inner tube, wherein the piston separates the internal volume into a compression chamber and an extension chamber; an outer tube surrounding at least a portion of the inner tube; an outer volume contained between the outer tube and the inner tube; a barrier that divides the outer volume into a first outer volume and a second outer volume, wherein the first outer volume contains both hydraulic fluid and a compressible medium; a hydraulic unit configured to convey hydraulic fluid between the compression chamber and the extension chamber via a first flow path that passes through the second outer volume.
