Abstract
Emitters and rotary hydraulic displacement pumps are associated with one or a number of propeller-type transducers and connected to receivers each having a rotary hydraulic displacement motor coupled to an alternator. The emitters are connected to the receivers by means of a hydraulic circuit for an auxiliary fluid which is admitted into at least one shunt-connected energy dissipator and the flow of which is regulated as a function of the random energy variations of the natural fluid. The energy-conversion system is primarily applicable to hydroelectric power plants of the stream or river type, to wind-driven power plants and to ship propulsion.
