DAMPING DEVICE WITH FIELD-CONTROLLABLE FLUID

The present invention relates to a damping device having a first control element with a first surface (O1) and a second control element with a second surface (O2), the two control elements being moveable relative to each other with their two surfaces, a spatial region (intermediate space Z) which is filled at least partially with a magnetorheological and/or electrorheological material (M) and is disposed between the first and the second surface, and a field producer (4) with which a magnetic and/or electrical field can be produced in at least a partial region of the material-filled part of the intermediate space, and also a housing (1) which has two chambers (K1, K2) and in which a piston unit (2) which is moveable relative to the housing and a closing unit (3) which is moveable relative to the piston unit are disposed, the piston unit and the closing unit forming a throughflow opening (D) connecting the two chambers, through which a fluid (F) can be displaced between the two chambers by means of a relative movement of piston unit and housing, the opening cross-section of the throughflow opening being able to be changed by means of a relative movement of piston unit and closing unit (3) and the closing unit and one of the control elements (O1) being coupled such that the relative movement of piston unit and closing unit can be controlled by means of the field strength in the intermediate space.
