Abstract (en)

[origin: WO2005049278A1] The invention relates to a clamping device (11) comprising clamping jaws (13) in which a plurality of clamping rods (16) are disposed. The clamping rods (16) are enabled to move by means of an interlinked system of rod chambers (22) and channels (24, 28) in which a magnetorheological fluid (26) is contained. If a magnetic field is applied by means of a magnet (30), the fluid solidifies, the liquid-carrying connection between the rod chambers (22) is interrupted and the rods (16) are fixed in a defined position.
