Abstract
The system includes oil accumulators on each side of the hydraulic pumps or motors, and a four-way valve for alternating between the inlet and outlet on one of the pumps or motors. The pumps are fitted on the gables of an electric motor gable, and their output shafts constitute those of the rotor. The arrangement therefore forms an assembly within the electric motor rotor, comprising electric motor, differential and equipment for changing the direction of rotation of the different shafts.
