摘要： Shock absorbing fork, especially a front fork (1), for a two-wheeled vehicle, particularly a bicycle, of the type having a pair of telescoping struts (3) and a hydraulically damped shock absorbing arrangement (15) disposed within each of the telescoping struts (3), the shock absorbing arrangement (15) having a piston (16) which divides a hydraulic fluid containing cylinder (19) into upper (21) and lower (22) chambers, a valve (24) regulating flow of hydraulic fluid through the piston (16) between the upper (21) and lower (22) chambers, and a piston rod (25) connected to the piston (16). Among the improvement of the invention is the provision of a spring (S) for absorbing shocks that acts on the piston (16) of the hydraulic shock damping arrangement (15) upon compression of the telescopic struts (3), and a location sensitive flow control arrangement (37) having a flow path (F) extending between opposite sides of said piston (16) and a flow adjusting element (39) which is displaceable into and out of said flow path (F) as a function of the extent which the spring (S) is compressed by compression of the telescopic struts (3).
