The invention concerns a double-rod shock absorber provided with two chambers, a compression chamber (1) and an expansion chamber (2); two rods, a compression rod and an expansion rod; two pistons, a compression piston (3) and an expansion piston (9), and two coil springs, a compression spring and an expansion spring (13). The compression piston is comfortably compressed as a result of the wide surface of comfort orifices, and returns to neutral position with control provided by the control valves (5) (in the first system) or by the control groove (11) (in the second system). The expansion piston extends comfortably as a result of the wide surface of comfort orifices, and returns to neutral position with control provided by the control valves (in the first system) or by the control groove (in the second system). Said shock-absorber solves the problem resulting from the relationship between speed and force. |
