Abstract: The present invention provides a system for managing large fluid flows at high pressures. This system consists of an elemental chamber the operation of which is based on energy transmission by “impact” resulting from the instantaneous discharge of a “motor fluid” at a given pressure to generate a “linear” movement that raises pressure and propels fluid. This system provides an increase in working fluid pressure more efficiently that any presently available system, thanks to the linear transmission of energy, making it highly efficient. The combined arrangement of these chambers allows the managing of high fluid flows at high pressures. This system permits power to be produced through a steam cycle without the need for a phase change, eliminating all condensation and pre-heating stage devices that are replaced by more efficient equipment not requiring the phase change.
