<p>Shock absorber (31) for a hydropneumatic vehicle suspension element, comprising a disk (32) fastened in an outer casing having ports (30, 38) for the passage of the hydraulic fluid, first elements (48, 49, 37a, 37b) allowing this passage in only one direction for some ports (30) and in the opposite direction for the other ports (38), and second elements (53, 54, 55) for fastening the first elements to the disk; the abovementioned first elements comprise, mounted on the two opposite faces of the disk (32), stacks (46, 47) of elastically flexible metal washers (46a-46c; 47a-47c) arranged in rigid annular deflectors (48, 49) located opposite the hydraulic-fluid passage ports (30, 38). The deflectors protect the flexible washers against any damage caused by the very high peaks of hydraulic pressure which occur on uneven ground.</p> |
