Abstract

The present disclosure relates to a hydraulic damper comprising a main tube, a piston assembly, a base valve assembly, and at least one hydraulic compression stop assembly cooperating with a compression valve assembly, and comprising a pin disposed slidably within the piston rod and biased to project an activating tip towards the compression chamber. Said compression valve assembly comprises at least one deflectable or floating disc covering compression flow passages, and biased by a piston member slidable along said axis and normally abutting a retaining surface, and a pressure chamber having one surface defined by a surface of said piston member abutting said retaining surface, wherein said pin upon sliding inside the piston rod facilitates a flow of the working liquid from the compression chamber into said pressure chamber to increase biasing load on said at least one deflectable or floating disc.
