Abstract:
A passive force element on the basis of electrorheological liquids, in which there is arranged a piston with a piston rod, which is guided in a cylindrical housing, whereby the piston rod is connected with a force introduction element, and whereby the piston forms, in the cylindrical housing, first and second variable-volume working chambers, which are filled with an electrorheological liquid, and which are connected via a fluid connection, and whereby the fluid connection comprises a valve arrangement for controlling a throughflow characteristic of the electrorheological liquid through the valve arrangement, which comprises an electrorheological liquid valve, characterized in that, a force introduction is achieved via the force introduction element, the piston is coupled onto the force introduction element via an elastic element formed by a gas volume that is arranged in the piston and can be acted on by the force introduction element, and the piston comprises at least one movably supported boundary wall.
