The damper (2) has a piston (4) comprising a rod (20) and a head (22) sliding in a cylinder (6) that is subdivided into lower and upper chambers (30, 32). A low discharge unit formed by a low discharge channel (50) and low discharge orifices (51, 52) connects the upper and lower chambers for a range of positions of the head. A high discharge unit formed by high discharge orifices (53, 54) and high discharge channel (54) connects the chambers for another range of positions, so that the damper provides high resistance between the ranges and low resistance over the ranges. |
