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.

Abstract translation: 线性能量收集装置，其包括壳体和活塞，当壳体和活塞从静止位置被压缩或延伸时至少部分地移动通过壳体。 当活塞移动时，液压油被加压并驱动液压马达。 液压马达驱动发电机发电。 电机和发电机都是设备外壳的中心。 公开了示例性配置，例如单管，双管，三管和基于旋转的设计，每个都包括集成的能量收集装置。 通过改变内部发电机的电气特性，可以动态改变能量收集装置的运动特性。 在另一种模式中，该装置可用作致动器以产生线性运动。 应用包括车辆悬挂系统（用作主要阻尼器部件），轨道车转向架阻尼器或工业应用，例如机械阻尼器和波浪能收割机以及电动液压致动器。
