The invention relates to gravitational hydraulic cylinders used for performing a rotary motion required to drive an electric generator, a pump or another subassembly. According to the invention, there are at least two gravitational hydraulic cylinders (1) arranged in vertical position and filled with working fluid, each cylinder (1) having a piston (11) and a rod (4) mounted at the lower part, said rod being engaged with a connecting rod-crank mechanism (3), the piston (11) being inserted between two bellows (5) fixed inside the cylinder (1) with the role of separating the two chambers and of delimiting the volume of fluid to be discharged, the use of bellows (5) being chosen with the purpose of preventing the friction of the piston (11) to the walls of the cylinder (1), and also two electric valves (7), two electromagnets (12), a circulation pump (8) mounted at the lower part of the cylinders (1), some pipes (2) for guiding the flow of liquid, the connecting rod-crank mechanism (3) and a speed multiplier (10) connected to the generator (9). |
