Abstract
The present invention relates to an electro-hydrostatic system () with a hydraulic machine () which is driven by an electric motor () and has a variable volume and/or rotational speed for providing a volumetric flow rate of a hydraulic fluid, a differential cylinder () with a piston surface and with an annular surface, and at least one equalization container (), wherein the drive system () has a closed hydraulic circuit and during operation has an overpressure relative to the environment by means of the hydraulic machine () and/or a pretensioning source (), and the drive system () provides a movement of the cylinder in a first direction by means of a volumetric flow rate of the hydraulic machine () and a volumetric flow rate from the equalization container (), and provides a movement in a second direction by means of a volumetric flow rate of the hydraulic machine () and a volumetric flow rate into the equalization container (), and a power operating mode and a speed operating mode are provided with the differential cylinder ().
