| 摘要 |
The invention relates to a device for controlling a valve (3) via a rack (9) that engages with an elliptical pinion (11) connected to a coupling (13) so that one transmits a torque to the other. The connections between the pinion and both the rack and the coupling are separable, so that the angular reference positions of the pinion with respect to both the rack and the coupling can be adapted in accordance with a predefined torque variation necessary for controlling the valve. |
