Abstract
The present invention relates to a hydraulic damper comprising a main tube; a main piston assembly; a base valve assembly; and a hydraulic compression stop assembly comprising an insert fixed on the base valve assembly, and an additional piston assembly apt to be introduced inside the first inner chamber of the insert at the end of the damper compression stroke to generate additional damping force. Said additional piston assembly comprises a piston rod extender fixed to the piston assembly or the piston rod at the side of the compression chamber, and a tenon fixed to said piston rod extender and radially displaceable with regard thereto, wherein said tenon is terminated with a first entry surface having diameter monotonically diminishing towards the compression end of said tenon, while the insert is provided with a second entry surface having diameter monotonically increasing towards the rebound end of the insert.
