Abstract
The invention provides a rotary shock absorber (10) of the type comprising a sealed hollow cylindrical housing (12) in which are arranged discs (50A, 50B) alternately integral in terms of rotation with the housing (12) or with a coaxial central shaft (22) mounted rotatably in the housing (12), the inner chamber (20) delimited by the housing (12) being filled at least partially with a viscous fluid received between the mutually confronting faces of the discs, characterized in that it comprises a displacement member (58) for varying the law of damping of the shock absorber as a function of the relative angular displacement of the central shaft (22) in relation to the housing (12).
