<p>The invention relates to a hydraulic shock absorber comprising a portion that is mobile along an axis, having a rod (4) connected to a piston (6) separating two closed chambers (8, 10), and comprising a flow-rate adjustment device (20) between said chambers, characterized in that said device comprises a mobile mass separating the chambers (8, 10) and attached by springs having an axial stiffness in order to form a resonator having an respective mode corresponding to a particular frequency to be absorbed, and a partition also separating said two chambers and attached to said mobile portion by springs, wherein said partition comprises fluid passages partially closed by elements connected to the mobile mass, resulting in a maximum passage cross-section when the mass and the partition have similar movements, and a minimal passage cross-section when the mass and the partition have opposite movements.</p> |
