Abstract: The invention relates to a hydraulic generator formed by a set of different specific chains which are coordinated and complement one another such as to allow floats to enter a tank and to force said floats along a predetermined path, in order to make maximum use of the upward force thereof. A first chain neutralizes the internal hydraulic pressure on the front of the floats, allowing the floats to be introduced at the bottom of the tank. Once a float has entered the tank, the first chain transfers the float to the second chain which uses the upward force of the floats and converts said force into mechanical work, in accordance with Archimedes' principle. The second chain drives the entire system. A third chain removes each float that reaches the surface from the tank and introduces said float into an external channel that returns the float to the entrance, assisted by a fourth chain and a moderate-pressure system that forces the float back in. The operation is repeated automatically and indefinitely.
