摘要 |
<p>The control element has a spinner (2) with multiple spinning arms (4) extending in a radial direction. The spinning arms are provided with hollow cylindrical spinning nodes (8). The spinning node extends in an axial direction. A control rod (6) is passed through the spinning node. The control rod is provided on an end with an outer thread. The end protrudes over the spinning arms. A screw nut (12) is fixed in end mounting position at spinning arms with intermediate pieces (20a,20b,20c) which is welded with the screw nut and the spinning arms.</p> |
