The shock absorber consists of a first double acting hydraulic cylinder, with piston (2) which has openings (3, 4) for the reflux of fluid between the chambers, the stem (10) is coupled to the upper support (12) : the lower chamber (6) is connected to the correction chamber (17) of a second cylinder which is rigidly attached to the lower support (22) of the shock absorber. An hydraulic connection (26) between the said correction chamber (17) and the annular chamber (20) of the second cylinder enables the fluid in the correction chamber to be recovered during retraction. The stem (1) of the second cylinder has, advantageously, a diameter which is larger than that of the stem (10) of the first cylinder. The shock absorber enables rapid reactions to dynamic loading, varied proportionately with the instantaneous load. <IMAGE> |
