SLEEVE FOR A DAMPER, DAMPER, SYSTEM, MANUFACTURING METHOD FOR A SLEEVE, MANUFACTURING METHOD FOR A DAMPER

The invention relates to a substantially tubular sleeve (12) for a damper (100). The sleeve (12) is designed for arranging in a damping chamber (110) of the damper (100), which damping chamber (110) contains a damping fluid, and comprises at least one clearance (20) at least in an inner surface (12i) of the sleeve (12), wherein the clearance (20) defines a flow duct for the damping fluid for the adaptation of the flow impedance (F) for the damping fluid at least in a direction along a longitudinal axis (LA) of the sleeve (12). Furthermore, the invention relates to a damper (100) having a substantially tubular sleeve (12) which is arranged in the damping chamber (110), wherein the sleeve is connected rigidly and preferably releasably to the outer body (1) via a number of contact surfaces (12-1) on an outer surface (12a) of the sleeve (12), and comprises at least one guide surface (12-19) which is arranged on an inner surface (12i) of the sleeve (12) for the guidance of the piston (19) over the stroke travel (H
