Abstract (en)
[origin: WO9966212A2] The invention describes a regulating device for at least two working tools (2, 3) operated with a hydraulic fluid, more particularly, hydraulic oil (7), e.g. cutters (4), expanders (7) used in mining, etc. each of which includes a tool (2, 3), a supply circuit (10, 11) for the hydraulic fluid (6) and at least one pressure generating device (9). At least one control device (15) formed by a control valve (23, 24) is mounted in the supply circuits (10, 11) for the working tool (2, 3). If required, fluid connection of the control valves (23, 24) is made possible through at least one connecting channel (25) or a connecting line.
