Abstract
This invention relates to a device for controlling and synchronizing the guide vanes of a distributor of hydraulic machines, particulalry of turbines, which comprises ramps borne by spaced apart radial tabs secured with the synchronization ring. Each lever fitted angularly on the journal of each guide vane presents a free end which cooperates with the corresponding ramp by a roller. The profile of the guide vanes is such that the hydrodynamic force tend to close them.
