Abstract
A shock absorber is made with a bleed function and preferably a non-return valve function associated with the bleed function. The shock absorber has a cylinder ( ) and, working in the latter in working medium and arranged on a piston rod ( ), a piston arrangement. The latter comprises at least two first and second pistons ( ) arranged at a distance from one another on the piston rod. At least one piston ( ) can, in connection with an end position, be introduced into a first space so as, depending on its position in or at the space, to bring about a modified or varied damping force relative to when the piston is located outside the space. The piston rod ( ) is provided with an inner second space ( ) which is arranged so as to contain said bleed and/or non-return valve function. Additionally or alternatively, the piston ( ) working outside the first space is provided with a member performing a bleed function and with any associated non-return valve function.
