ABSTRACT:
A telescopic fork leg incorporates mutually displaceable inner and outer tube parts and a damping arrangement for damping the relative movements of the tube parts. The damping arrangement comprises tubular and coaxially disposed units. A piston belonging to a first outer tube part operates in a chamber within the interior of the tubular units in a medium present in the chamber, which medium, at a piston speed above a chosen value, is transferred between the top and bottom sides of the piston via passage(s) disposed in, on or by the piston and adjustable damping-influencing members. The passage(s) is/are closed by the damping-influencing member(s) at piston speeds below the chosen value and the medium is conducted only via one or more leak flow paths extending from the chamber on one side of the piston, via a gap between the outside of the inner tubular unit and within a second tubular unit disposed outside the inner unit, one or more leak-flow-size-determining members, and back to the chamber on the other side of the piston. Independently adustable compression and the return leak flows can be easily arranged around the piston and an important component in the leg can provide a strength function and a leak-flow-conducting function.
