Abstract

Outil rotatif actionné par un fluide et commandé par un mécanisme sensible au couple. Un tel outil comprend un mécanisme sensible au couple qui commande l'obturateur d'une valve en dégageant une tige de commande allongée. Un siège mobile de la valve est poussé vers une première position par le fluide sous pression alimentant l'outil et lorsque la tige de commande est libérée, l'obturateur de la valve porte contre le siège pour- interrompre l'écoulement du fluide dans le moteur de l'outil Lors de la fermeture d'un clapet commandé par l'opérateur, le siège est poussé vers une seconde position dans laquelle il rappelle la tige de commande et l'obturateur à leur position initiale. Application aux outils pneumatiques destinés à serrer des vis ou des écrous.
