  • Valve control device
    Patent number: 10563791
    Abstract: A device for actuating a valve by means of a rack meshing with an elliptical pinion connected with a sleeve so that one transmits a torque to the other. The connections between the pinion and the rack as well as the sleeve are separable, so that the angular reference positions of the pinion relative to both the rack and the sleeve can be adapted according to a predefined variation in the torque required for actuating the valve.
