The device has upper and lower armatures (10, 14) integrated with respective structural units. Hydraulic chambers (A, B) filled with a fluid are separated by a partition (22) which has a passage through which the fluid flows. The fluid has a viscosity between 20 and 100000 centistokes at an ambient temperature. The passage has sections with openings whose dimension is lower than or equal to thickness of a boundary layer of the fluid.
