Abstract

The invention relates to a controllable adjustment and damping device comprising at least one pressure chamber (4) filled with hydraulic fluid, a fluid container (11), a pump (5) connecting the pressure chamber to the fluid container, a compensating volume (8) and a return line (13) with a passthrough valve (7). An electro-rheological fluid or magneto-rheological fluid is used as a hydraulic fluid (6) which exerts pressure upon a piston (3) that juts out into the pressure chamber or on a membrane (17), the intensity thereof being controlled by the passthrough valve.
