Abstract

A known shock absorber including a throttle cross section of a throttle passage which is electrically variable via a magnet, to adjust damping of fluid between separate work chambers. If the magnet has no current in the event of an electrical defect, then the throttle cross section of the throttle passage attains its minimum opening, and maximum damping is attained the shock absorber includes a different further throttle passage which is uncovered in the event of an electrical defect. As a result, in the event of an electrical defect an arbitrarily preselectable, preferably approximately average damping is brought about by the further throttle passage.
