Abstract

Appareil d'arrêt pour outil pneumatique. Cet appareil comporte une soupape d'arrêt auxiliaire 34 disposée dans le passage d'alimentation en air comprimé du moteur 24 de l'outil. La soupape est commandée par une tige 38 qui traverse le moteur et se termine dans l'arbre de sortie 30 en appui contre un organe d'encliquetage 46 lequel est maintenu dans la position encliquetée avec la soupape ouverte par un organe lesté 56 monté pivotant sur l'arbre de sortie 30. Cet organe lesté est sensible à l'inertie de sorte que, lorsque la vitesse du moteur diminue par suite de l'accroissement du couple résistant, l'organe lesté pivote, libérant lorgane d'encliquetage 46 et permettant à la soupape d'arrêt 34 de se fermer. Application par exemple à une clé dynamométrique.
