Abstract: A hydraulic damper assembly comprises a housing extending between a first end and a second end. A main piston is slidably disposed in the fluid chamber dividing the fluid chamber into a first chamber and a second chamber. A piston rod extends along a center axis and attaches to the main piston. An additional piston is coupled to the piston rod and axially spaced from the main piston. The additional piston includes a main body defining a compression channel and a rebound channel that allow fluid to flow through the additional piston. A securing member secures the additional piston to the piston rod and defines an outer groove. A piston ring is located in the outer groove between the additional piston and the securing member. The piston ring is radially spaced from the securing member to allow the piston ring to be in engagement with the housing.

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.
