Abstract
Official abstract text for this publication.
A hydraulic pump is driven by a rotating shaft, driven in turn by a renewable energy source. A hydraulic motor drives a load and a high pressure manifold communicates between the pump, motor and an elastically deformable fluid retaining body. The pressure in the high pressure manifold is measured and the net rate of displacement of working fluid by the hydraulic pump is selected responsive thereto to regulate the torque applied to the rotating shaft. The net rate of displacement of working fluid by the hydraulic motor is selected to smooth the energy flow to the load. The net rate of displacement of working fluid by the hydraulic motor is selected to regulate the pressure in the high pressure manifold to remain within an acceptable pressure range.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of operating an energy extraction device to extract energy from a fluctuating energy flow from a renewable energy source, the device comprising: a hydraulic pump driven by a rotating shaft, the rotating shaft driven by a renewable energy source, a hydraulic motor driving a load, at least one low pressure manifold and a high pressure manifold in fluid communication with an outlet of the hydraulic pump, an inlet of the hydraulic motor and an elas…
