Abstract

A shock absorber which in an event of an electrical defect provides a predetermined throttle cross section which provides a pressure drop in the throttle cross section that determines damping of fluid flow from one work chamber to another work chamber. Thus, in an event of a defect in a control system, an arbitrarily selectable and preferably approximately average damping is produced.
