Abstract

A Pelton hydraulic machine through which a main flow of water passes including at least one Pelton turbine manifold with at least a turbulent zone or a reduced-pressure zone being formed close to the manifold and wherein a secondary flow drawn from the main flow, and unaltered in relation to the main flow, is injected into the turbulent or reduced-pressure zone so as to alter the main flow locally or increase the pressure in the zone.
