Abstract
Mechanism for obtaining a couple for maneuvering a part to make it rotate on itself through a quarter turn, from a member moving along a trajectory, via a transmission such that the curve representing the reduction coefficient, which is the ratio of the maneuvering couple to a nominal couple, shown on the y axis, as a function of the angle of rotation, shown on the x axis, is convex, the curve rotating its convexity upwards and the peak coefficient of reduction being obtained for an angle of about 20 to 40°.
