Abstract
A telescopic fork leg with damping system comprising piston and piston rod arrangements. The arrangements perform longitudinal shift motions in a medium-containing chamber. The chamber is situated in a tubular part belonging to the damping system. The piston rod arrangement is designed so as in the chamber, with its parts present therein, to have substantially constant volume regardless of the shift motions. Substantial displacement creation is thereby prevented. Moreover, the medium strives to assume and maintain a particular pressure, preferably a positive pressure, on the low-pressure side of the piston arrangement. Positive pressure build-up is therefore present in the damping system and the pressure on the low-pressure side does not need to be lower than the system pressure. A valve arrangement for handling a displacement can therefore be eliminated and the telescopic fork leg can be given an advantageous and easy-to-use structure with, for example, adjustment facilities for leak flows.
