ABSTRACT:
In working cylinders whose power stroke can be shifted to different operating positions in two consecutive steps, the invention provides a control cylinder which is actuated independently of the generation of working pressure. The control cylinder acts on a joint lever which alters the distance between two separate parts of the power transmission to the tool and thus the effective length of the transmission. This arrangement has the advantage of small working volumes and low energy consumption.
