Abstract (en)
The hydraulic system has a hydraulic pump (1) driven by a battery-operated electric motor (3) and supplied from a hydraulic reservoir (10). The battery (2), the drive motor, the pump and the hydraulic reservoir are all contained in a compact portable module (A), with the pump coupled via a hydraulic line (4) to an interchangeable hydraulic tool. Pref. the remaining battery charge is indicated by a display (13) incorporated in the outside of the portable module, with a protection circuit (14) for electrical protection of the electric motor. An electric switch, associated with the hydraulic tool for switching the electric motor, is pref. coupled to module via an electrical line incorporated in the hydraulic line. <IMAGE>
