Abstract
A dual-screw movement converter, in which a movement converter between a drive organ includes a screw fixed in translation and driven in rotation, having threads, a nut connected in translation to the receptor organ, having first threads engaging with the threads of the screw and second threads. A sleeve coaxially surrounds the nut, fixed in rotation and translation with respect to the screw and having threads with which the second threads of the nut engage. To the nut, slaved by its second threads to the threads of the sleeve, screw communicates a combined movement of rotation and translation whose translation component along an axis is transmitted to the receptor organ.
