Abstract: Rotary damper (15), comprising a casing (17), an intermediate element (31) mounted on the casing (17), a braking fluid provided between the casing (17) and the intermediate element (31) so as to brake the movement of the intermediate element (31) relative to the casing (17), a rotor (50) mounted on the intermediate element (31) rotably about an axis of rotation (x), and a unidirectional coupling arranged between the intermediate element (31) and the rotor (50). The unidirectional coupling comprises at least one radial block (60) arranged between a radially outer surface (52) of the rotor (50) and a radially inner surface (34) of the intermediate element (31), and at least one actuating lobe (55) formed on the rotor (50) and projecting radially from the radially outer surface (52) thereof, the radial bock (60) comprising a wedge part (61) designed to be engaged by the actuating lobe (55) of the rotor (50) during rotation in the first direction of rotation (A) so as to push the radial block (60) in the centrifugal direction and lock it between the rotor (50)

Abstract: Shock absorber comprising a tubular base, a piston, a stem connected to the piston, and a plurality of fluid paths for connecting a working chamber and an accumulation chamber on opposite sides of the piston, one of which provides for a ring-shaped obstructing member arranged about the piston and able to slide along an axial length of the piston. The obstructing member comprises a bush of plastic material, which has a flexible lip portion extending from a rear end of the bush and having a radially outer surface tapered towards the rear end of the bush, the lip portion being adapted to seal against a radially inner surface of the base when the obstructing member is in a closed configuration. A support ring member is adapted to radially engage the lip portion of the bush from within, and to push it against the radially inner surface of the base.

Abstract: Rotary damper (15), comprising a casing (17), an intermediate element (31) mounted movably on the casing (17), a braking fluid provided between the casing (17) and the intermediate element (31) so as to brake the movement of the intermediate element (31) relative to the casing (17), a rotor (50) mounted on the intermediate element (31) rotatably about an axis of rotation (x), and a unidirectional coupling arranged between the intermediate element (31) and the rotor (50). The unidirectional coupling comprises at least one radial block (60) arranged between a radially outer surface (52) of the rotor (50) and a radially inner surface (34) of the intermediate element (31), and at least one actuating lobe (55) formed on the rotor (50) and projecting radially from the radially outer surface (52) thereof, the radial bock (60) comprising a wedge part (61) designed to be engaged by the actuating lobe (55) of the rotor (50) during rotation in the first direction of rotation (A) so as to push the radial block (60) in the centrifugal direction and lock it between the rotor (50) and the intermediate element (31).
