PURPOSE: A damping force regulating buffer is provided to regulate the damping characteristic in low speed area without change of relief pressure and controls the relief pressure of main damping valves variably without the damping characteristic in low speed area. CONSTITUTION: A damping force regulating buffer comprises a cylinder(1), a piston(6), a piston rod(7), main damping valves(14, 19), first orifices(27, 29), second orifices(28, 30), and a back pressure chamber. Working fluid is filled in the cylinder. The piston comparts the cylinder into two chambers. The main damping valves are installed in a first passage for restricting the working fluid flow. The first orifices are installed in a second flow passage located in the downstream of the first orifices and installed in the second flow passage. The back pressure chamber pressurizes the main damping valves into closing direction. |
