Abstract
Damper device for damping relative movements of two elements of a mechanical system. The damper device comprises a damping chamber filled with a hydraulic fluid, a rod () having a piston () movable in the damping chamber so as to define two hydraulic compartments (), at least one calibrated orifice () provided in the piston () for throttling the hydraulic fluid flowing from one hydraulic compartment () to another hydraulic compartment, at least one compression peak-limiting valve () and a traction peak-limiting valve (), throttling the hydraulic fluid flowing from one hydraulic compartment () to another hydraulic compartment. The damper has additional hydraulic means that are active in compression and in traction when the piston () reaches the end of its stroke, so as to constitute a progressive hydraulic abutment damping the end-of-stroke jolts.
