Abstract

A frictional damper has a tubular housing and a slide which is guided slidably in this housing in the direction of its longitudinal axis. In the area of its end on the slide exit side, the housing is provided with a damping lining which bears against the slide. In order to achieve the setting and maintaining of constant frictional conditions, which can if necessary be varied from one frictional damper to another, at low cost, the damping lining is arranged in a separate damping housing which is inserted into the tubular housing from the end on the slide exit side and is fixed axially at this point in the direction of its longitudinal axis. In an otherwise identical housing and slide the damping housing and/or the damping lining can each have a different design.
