Title:
FLUID POWER GENERATOR
Document Type and Number:
WIPO Patent Application WO/2003/040557
Kind Code:
A1
Abstract:
A fluid power generator using working fluid energy as a drive source, which makes power generation possible that has a continuous variable output corresponding to a wide range of flow rate, wherein with the object of achieving a power increase (at least 40% more than in the prior art) by obtaining a maximum output at each flow rate of the working fluid, power generators of optimum rated output are combined by selecting them from a plurality of power generators according to the natural fluid energy and the rpm of the vane rotating shaft, including an operation mode having a continuous variable output corresponding to a wide range of flow rate, and a control means for controlling the operation of the individual power generators in the operation mode on the basis of the peripheral velocity ratio calculated from the flow rate of the working fluid and the rpm of the vane rotating shaft, whereby a maximum output can be obtained at each flow rate of the working fluid.
