Patent ID: 7377372

Claim:
A telescopic fork leg with a damping system, comprising: a piston having a low-pressure side; a chamber provided with a medium situated in a first tube of the damping system; one or more piston rod arrangements, designed to perform longitudinal shift motions in said chamber, comprising: a piston rod part, configured to extend from said first tube; a second tube situated inside the first tube, at a first end of the first tube, and against whose inner face the piston rod part is sealed against the chamber; and a third tube having the first tube disposed therein via an intervening gap, wherein the first tube is provided with one or more medium passages on both sides of the piston rod arrangement, wherein the second tube is designed to seal off the damping system from the surrounding atmosphere, and wherein the piston rod arrangement is configured to maintain substantially constant volume regardless of the shift motions and thereby to prevent substantial displacement of the medium and to cause the medium to strive to assume and maintain a particular pressure on the low-pressure side of the one or more piston arrangements.
