Abstract

L'invention concerne un tournevis à air comprimé à limitation de couple. Un tournevis comprend une soupape d'admission 16 commandée par une tige de soupape 15 coulissant dans un perçage axial 23 d'une première pièce 4' de la broche 4. Lorsque, par suite de dépassement du couple nominal, la tige de soupape 15 a refermé la soupape 16, une nouvelle poussée sur l'outil vient mettre en contact l'extrémité de la tige de soupape 15 contre le fond 22 du perçage 23, ce qui provoque la remise en marche du tournevis avec un couple plus élevé que le précédent et déterminé par la tension préalable d'un ressort 10. L'invention s'applique aux tournevis à air comprimé.
