Abstract
Damping device to impose a reaction to the displacement of a manual operating device (28), said device comprising at least one chamber containing the magneto-rheological fluid, one or two means of generating a variable magnetic field (6.1, 6.2) in the magneto-rheological fluid so as to modify its apparent viscosity, one element (4) free to move in translation capable of shearing the magneto-rheological fluid and designed to be mechanically connected to the manual operating device (28), said mobile element (4) comprising a blade with a longitudinal axis (Y) comprising holes and/or recesses and/or projections.
