A shock absorber comprising a damping cylinder is divided into a first damping chamber and a second damping chamber by a main piston device. The main piston device comprises a first main piston and a second main piston. The main pistons comprise continuous ducts that are delimited in a direction of flow by first and second flow limiters. The main pistons are mounted on a piston rod. The piston rod has an axially extending and continuous cavity through which damping medium can flow between a pressurized chamber and a respective damping chamber. The damping medium flows via an interspace delimited by the first main piston and the second main piston out into the damping chambers via pressurization ducts delimited by the first flow limiters. The first flow limiters lift axially from the main piston with substantially maintained external form in the opening process so that a flow path is created both between the main piston and the whole or parts of the inner periphery of the first flow limiter as well as between the main piston and the outer periphery of the first flow limiter. |
