<p>A hydraulic shock absorber includes disc valves (46, 47) seated on valve seats (38, 39), and annular retainer discs (120, 121) having a diameter less than that of the valve seat. The retainer discs are guided by spacers (200, 201) and axially separable from the disc valves. Annular seal discs (54, 55) are disposed downstream of the disc valves. The inner periphery of the seal discs is partly overlapped with the outer periphery of the retainer discs. The outer peripheral edge of the retainer discs is in substantially linear contact with the disc valves. This arrangement restricts friction resistance between the disc valves and the retainer discs when the disc valves are flexed and opened. <IMAGE></p> |
