Abstract
A damping valve for a vibration damper includes a guide sleeve which slides on the piston rod of a vibration damper. An annular damping valve body which is provided with at least one through-opening is fixed axially by positive engagement on the guide sleeve, and the through-opening is covered at least partly by at least one valve disk which is biased by at least one closing spring which is supported at its end at a spring plate connected to the guide sleeve. The damping valve body and a spring plate which is constructed separate from the guide sleeve form a compression chain between two axially spaced stops of the guide sleeve.
