A hydraulic damper (2) comprises a tube (3) filled with working liquid, inside of which a slidable piston assembly (4) is attached to a piston rod (6) and provided with at least one valve assembly (43) to control the flow of working liquid passing through the piston assembly (4) during rebound and compression stroke of the damper. The valve assembly (4) contains a floating disc valve (431) and additionally comprises a unidirectional check valve disc (436) disposed serially with the floating disc valve (431) across the passage of the flow of working liquid during compression or rebound stroke of the damper (2). Preferably the piston assembly (4) forms a symmetrical cross-flow arrangement and preferably the at least one valve assembly includes compression (43a) and rebound (43b) valve assemblies of the piston assembly (4) which each have the same constructions.
