Shock absorber for road vehicle - has piston with twelve axial bores covered by disc springs

Abstract

Abstract The shock absorber (1) has a piston (5) sliding in a cylindrical housing (2). The piston (5) has a total of twelve equally spaced holes. Eight of these holes (21) break into slots (21b) on the piston upper face and four holes (22) break into slots (22b) on the lower face. Disc springs (6, 7) cover the holes (21, 22) and are clamped against the slightly dished faces of the piston (5) by the washers (8, 9), retaining rings (10, 11) and nut (13). The disc springs form non-return valves, the four holes (22) offering more resistance to oil flow, as the piston moves upwards, than do the eight holes (21) as the piston rebounds.
