<p>The absorber unit has a sensor carrying unit (20) with a sensor unit (26) and a longitudinal guiding unit (50), and a cylinder (16) connected with a mounting point. Another sensor unit (32) is attached to the cylinder in such a manner that the unit (32) moves with the cylinder in an axial direction, while the unit (32) is rotated opposite to the cylinder. The unit (32) has an engaging unit (52) working together with the guiding unit in such a manner that a radial alignment of the unit (32) to the unit (26) persists during rotation of the cylinder opposite to the carrying unit.</p> |
