<p>The damper has a first damping element (12) arranged about the axis of rotation and having a helical cam surface (22). A second damping element (17) set rotating relative to other damping element for displacement along cam surface, corresponding to one of the helical pitches between damping elements, is dampened indirectly, leading to the damping of rotational movement. The first cam surface automatically changes into the second cam surface (23) which imposes a gradient with the opposite direction to the pitch of other cam surface, by the rotational movement. An independent claim is included for a construction kit for toilet.</p> |
