<p>Operating device (1) for a control system with two cables (3a, 3b) comprising a pivoting lever (6), mechanical links between the lever (6) and the cables, each cable being linked to a control stem (7a, 7b) and each stem being extended by a rack gear (8a, 8b) interacting with a toothed sector (9a, 9b) linked to the said lever (6) by meshing with the said rack gear, characterised in that the mechanical link between the lever (6) and the first cable (3a) comprises a shaft (10) pivoting around its axis (10a) and linked operationally to a first toothed sector (9a) meshing with the rack gear (8a) of the first stem (7a) and a coupling member (12) articulated onto the said shaft and in that the mechanical link between the lever (6) and the second cable (3b) comprises a pivoting fork (14) linked functionally to a second toothed sector (9b) meshing with the rack gear (8b) of the second stem (7b) and between the branches (14', 14'') of which is movably engaged a spherical ball joint (15) integral with the said coupling member. <IMAGE></p> |
