Abstract

L'invention concerne un dispositif de mise sous tension pour serrer des boulons. Ce dispositif comporté une rondelle dont l'alésage central est traversé par le boulon. Un corps allongé 18 à haute résistance entoure cette rondelle et présente une face terminale évidée 20 contenant un piston annulaire 22 susceptible de se déplacer, sous l'action de moyens hydrauliques, parallèlement à l'axe de l'alésage de façon à assurer le serrage désiré. Application : dispositifs de serrage de boulons.
