Abstract
The invention relates to a hydraulic damper, in particular for the suspension system of a motor vehicle, comprising a tube filled with working fluid; a piston assembly slidably positioned inside the tube; a fluid compensation chamber located outside of the tube, and a base valve assembly at the end of the tube for controlling the flow of working fluid between the tube and the compensation chamber. A compression valve module added between the piston assembly and the base valve assembly allows the damping to increase during extremely fast compression strokes without modification of the other damper components, affecting neither tuning options nor performance in a normal operating range of piston velocities.
