Abstract
The invention relates to a suspension hydraulic damper () comprising a tube () filled with working liquid, inside of which a slidable piston assembly (), provided with compression () and rebound () valve assemblies and attached to a piston rod () led outside the damper (), is placed, and at least one compression valve system (). To increase an amount of dissipated energy during extremely fast compression strokes the compression valve system () comprises at least one substantially thin closing element (), preferably in a form of a flat floating disc, having an outside diameter less than the inner diameter of the tube () and being axially slidable with respect to the piston rod () axis, a spring () surrounding the piston rod () axis and pressing the closing element against a retainer () into an open position, an abutting surface () for the closing element () in a closed position, and at least one passage () for the flow of damping medium in the closed position.
