Abstract
The invention relates to a damper arrangement, in particular an air spring strut, comprising a shock absorber having an essentially cylindrical housing and an air spring with a working space which is under internal pressure, and comprising an additional volume which can be connected to the working space via a closable flow duct. It is proposed to enclose the additional volume by a hollow body which surrounds the shock absorber which can be fastened thereto and is formed from an outer cylinder and an inner cylinder, which is connected to the latter and, in particular, is arranged concentrically.
