Abstract

L'invention concerne un dispositif pour casser la glace et dévier la boue dans un ensemble vis et écrou à billes et qui comprend une bague pouvant s'adapter non rotative dans une partie extrême de l'écrou et un extracteur s'étendant hélicoïdalement autour de l'intérieur de la bague à un angle d'avance correspondant à celui de la gorge de la vis. Selon l'invention, l'extracteur est formé d'une bande flexible 37 fixée à la bague 21 et s'adaptant dans la gorge 14 de la vis 12, la bande 37 ayant une extrémité adjacente au bord externe de la bague, et l'extracteur comprend de plus une pièce d'insertion 36 séparée de la bande et en un matériau sensiblement inélastique, adjacente à l'extrémité de la bande et s'étendant sur une distance circonférentielle plus courte que la bande, ainsi qu'un moyen élastique 46 agissant sur la piece 36 et la sollicitant radialement vers l'intérieur dans la gorge 14. L'invention s'applique notamment à la manoeuvre des volets des avions.
