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 1):
A hydraulic suspension actuator of a vehicle, comprising:\n an integrated unit including:\n a hydraulic unit; \n an electric machine operatively coupled to the hydraulic unit, wherein the hydraulic unit includes a first port and a second port, wherein the hydraulic unit is configured to operate as a hydraulic pump, and \n wherein the electric machine is configured to operate as an electric motor; a multi-tube damper assembly including:\n an inner tube; \n an outer tube that at least partially surrounds the inner tube, wherein a first volume is located between the inner tube and the outer tube; \n a piston, slidably received in the inner tube, wherein the inner tube includes a second volume containing hydraulic fluid and a third volume containing hydraulic fluid, wherein the second volume and the third volume are separated by the piston, wherein the first volume is fluidly connected to at least one of the second volume and the third volume; \n a compressible medium contained in a portion of the first volume; \n a first fluid flow path that fluidly connects the second volume and the third volume; \n a second fluid flow path that fluidly connects the second volume to the third volume, wherein the second fluid flow path bypasses the hydraulic unit; and \n a first valve configured to control a fluid flow in at least one path selected from the group consisting of the first fluid flow path and the second fluid flow path.
