Abstract
A hydraulic damper (3) includes a tube (4), a piston assembly (5) disposed slidably inside the tube (4), and an additional valve assembly (13). A compression chamber (9) is defined between the piston assembly (5) and the additional valve assembly (13). An additional compensation chamber (14) is defined between the additional valve assembly (13) and one side of a slideable partition (10). A gas chamber (11) is defined at the other side of the slidable partition (10). The damper includes an additional chamber assembly (15) to retain all the advantages of a twin-tube damper while providing the single construction offered by a mono-tube damper. One end of the additional chamber assembly (15) is attached to the slidable piston chamber (5) or to said piston rod (6) at the compression side thereof and the other end of said additional chamber assembly (15) is terminated with the additional valve assembly (13).
