PURPOSE: A damper gear for controlling the height of a vehicle is provided to make pumping response property fast, to reduce width of stiffness, and to control occurrence of cavitation. CONSTITUTION: A damper gear for controlling the height of a vehicle comprises an inner cylinder(15), a piston rod installed to the inner cylinder, a piston(3), a body valve, a rod guide a base chamber(1), a gas chamber(5), a high-pressure chamber, a pump tube(10), a pump rod(9), an inlet valve(6), and an outlet valve(7). The base chamber is formed between the inner cylinder and the outer cylinder(16). The pump and the pump rod are installed to the hollow hole of the piston rod. The inlet and outlet valve is installed at an end of the pump rod and the piston rod. The damper gear for controlling the height of a vehicle has a check valve(30) exhausting air from the pressure chamber to the base chamber. The pumping response property is quickened if exhausting air with using the check valve after filling oil and cavitation is controlled.
