Patent ID: 7255210

Claim:
A telescopic fork leg for a vehicle, said telescopic fork leg comprising: an outermost tube having bushings; and a damping arrangement comprising: a first inner tube arranged to run on said bushings, said first inner tube being arranged to provide a strength establishing function and a leak-flow conducting function, wherein said first inner tube and said outermost tube are displaceable with respect to each other; a second inner tube coaxial with said first inner tube and disposed inside said first inner tube; a piston attached to said outermost tube and arranged to operate within an interior chamber defined within said second inner tube, said chamber being divided into a top chamber portion bounded by a top side of said piston and a bottom chamber portion bounded by a bottom side of said piston; a medium disposed in said interior chamber; passages disposed between said top side of said piston and said bottom side of said piston; damping-influencing members associated with said passages, wherein said damping-influencing members are arranged such that said medium passes between said top side of said piston and said bottom side of said piston via said passages when a speed of said piston is greater than a certain value; a gap disposed between an outside of said second inner tube and an inside of said first inner tube; a first one-way valve function; a first leak-flow-size-determining member; a first leak flow path extending from said bottom chamber portion through said gap and to said top chamber portion, said first leak flow path being establishable in a compression direction of said outer tube and said first inner tube by means of said first one-way valve function and said first leak-flow-size-determining member, wherein said first leak flow path is establishable irrespective of the speed of sad piston; a second one-way valve function; a second leak-flow-size-determining member; and a second leak flow path extending from said top chamber portion through said gap and to said bottom chamber portion, said second leak flow path being establishable in an expansion direction of said outer tube and said first inner tube by means of said second one-way valve function and said second leak-flow-size-determining member, wherein said second leak flow path is establishable irrespective of the speed of said piston, and wherein said first leak flow path and said second leak flow path are arranged so as to not mutually influence one another.
