Abstract

The cylinder (1) consists of a cylinder tube (3) and a damping tube (4) connected to the cylinder tube. The damping tube has a flow off notch (23) which extends along the entire length of the cylinder. The central axis (24) of the notch is inclined with respect to the central axis of the cylinder at a tangent of 0.02 to 0.3.
