Abstract
A telescoping fork for the front wheel of a two wheel vehicle comprises a pair of outer tubes that each have a bottom end and a top end. An upper structural member and a lower structural member connect the outer tubes. Further, each outer tube tapers outwardly, both externally and internally, in a direction from the bottom end toward the lower structural member and from the top end toward the lower structural member. The structural members may attach to a top and bottom of a steering column.
Claims3
A fluid damping system, comprising:
- a tube member having a closed end and an open end;
- a hollow damper rod extending through the open end of the tube member;
- a damper piston valve coupled to the damper rod and movable within the tube member, wherein the damper piston valve comprises a one-way valve that permits fluid flow in an upward direction upon compression;
- a sealing member disposed to create a seal between the tube member and the damper rod near the top end of the tube member;
- a sleeve disposed over a top portion of the damper rod;
- wherein the damper rod includes at least an upper orifice and a lower orifice that are located between the seating member and the piston valve to permit fluid flow past the piston valve by passing through the damper rod during extension of the damper rod out of the tube member, wherein the lower orifice is manually closable, and wherein the sleeve is configured to close the upper orifice upon extension such that further extension is limited if the lower orifice is closed.
