Abstract:
A method for the path-dependent control of the force generated by a first piston, comprising the steps of:providing the first piston for travelling in a first cylinder that is divided into a first and second chamber by the first piston, providing a pressure fluid being conducted into the first chamber, providing a second cylinder in which a second piston travels and that is also divided by the second piston into a first and a second chamber, coupling the two pistons so that the second piston is pulled along by the first piston, and connecting the second chamber of the first cylinder to the first chamber of the second cylinder so that the same pressure prevails in both chambers, wherein the pressure in the second chamber of the second cylinder is regulated such that it is always equal to the counterpressure in the first chamber of the second cylinder and the second chamber of the first cylinder.
