Hydraulic shock absorber with adjusting of shock absorbing type

摘要

A shock absorber (1) includes a compression chamber (2) in which a piston (3) moves along a path of travel from a near end to a far end. The chamber includes a constant force mode bleed orifice (10) adjacent the far end and a series of progressive force bleed orifices (9a-9e) at spaced intervals between the near and far ends. An adjustment cylinder (12) has sloping arcuate apertures (13a-13e). As the cylinder (12) is rotated, one of the arcuate apertures aligns with the constant force orifice or the apertures align with the progressive force orifices in full or in part.
