VARIABLE DAMPING-CHARACTERISTICS SHOCK ABSORBER WITH ADJUSTABLE ORIFICE CONSTRUCTION VARIABLE OF FLUID FLOW RESTRICTION DEPENDING UPON FLUID PRESSURE DIFFERENCE

摘要

A shock absorber having an approximately linear variation of damping force with piston stroke speed includes a first damping force generating means (pathway 7e', 7e, 7c, B) providing greater variation at low piston speed and a second damping force generating means (pathway 3c, 15b/15c, 15a, 15d/15e, 3d, 7j, 7d, B) providing greater variation at higher piston speeds. The damping force generating means can comprise (Fig 4) a bottom valve pathway having two disc valves in series. IMAGE
