Shock absorber and method for calibrating same

Abstract

A shock absorber (1,1 ', 1 ", 1'", 1 "", 1V) has a housing tube (2), a coaxially arranged therein pressure tube (4) and a piston (5) radially sealed in the axial direction in the pressure tube (4) is displaceable. A piston rod (6) of the piston (5) is sealed out through an end face of the housing tube (2) and the piston bounded together at least with the pressure tube (4), an Arbcitsraum (11) from which a fluid due to movement of the piston (5) in the axial direction by at least one throttle opening (36) defining a throttle opening (17) and the throttle effect in a second working space (14) and / or a storage space can be displaced. In order to enable a repeated adjustment of the damping characteristic very quickly and without much effort, it is proposed that the effective throttle cross-section (36) can be changed by means of a remotely controllable drive device (18). Furthermore, the invention relates to a method for adjusting a shock absorber.
