<p>A telescopic leg forming part of a front fork comprises displaceably arranged outer and inner parts (3, 4). Within the leg parts there is disposed a first chamber (10) for liquid and gas medium (12), together with a control and sealing arrangement between the leg parts, in which a second chamber (21) between a first end of a control element and a sealing element (19) is intended to accommodate some of the liquid medium (12a). The second chamber is provided with or connected to a medium supply arrangement which, irrespective of the mutual positions and movements of the outer and inner leg parts, ensures a supply of medium from a third chamber (22), disposed between the leg parts and at the second end of the control element, to the second chamber. The supply of medium substantially counteracts pressure reduction in the second chamber and ensures maintenance of the said lubrication function. With the invention, pump-up effects in the telescopic leg due to infiltrating air via an outer sealing element are avoided. Vibrations and jolts transmitted to the handlebars during riding of the motor cycle can also be substantially reduced.</p> |
