  • Patent number: 6749045
    Abstract: A passive force element on the basis of electrorheological liquids includes a piston with a piston rod guided in a cylindrical housing, and a force introduction element connected with the piston rod. The piston forms, in the cylindrical housing, two variable-volume working chambers, which are filled with electrorheological liquids, and which are connected by a fluid connection including a valve arrangement with an electrorheological liquid valve for controlling the throughflow characteristic. A regulated damping characteristic can be adjustedly set and force peaks are avoided, because the force introduction is achieved via the force introduction element, and the piston is coupled onto the force introduction element via an elastic element.
