Abstract

L'INVENTION CONCERNE UN MECANISME D'ARRET DU MOTEUR D'UN OUTIL A FLUIDE, EN FONCTION DE LA VITESSE. LEDIT MECANISME COMPREND UN MOYEN 38, 40 CONSTITUANT UN CONDUIT DE SORTIE DU FLUIDE, MENAGE DANS LE CORPS 32 DE L'OUTIL 10 ET PAR LEQUEL CE FLUIDE QUITTE LE MOTEUR 14. UN OBTURATEUR 66 PEUT ETRE MIS DANS UNE POSITION D'OUVERTURE, POUR PERMETTRE AUDIT FLUIDE D'ECHAPPEMENT DE PARCOURIR LE CONDUIT, ET DE FERMETURE, DANS LAQUELLE IL BLOQUE LEDIT FLUIDE ET ARRETE LE MOTEUR. UN MOYEN 64, 72, SENSIBLE A LA DECROISSANCE DE LA VITESSE DU MOTEUR 14, AMENE LEDIT OBTURATEUR 66 A SA POSITION FERMEE. APPLICATION AUX OUTILS PNEUMATIQUES, TELS QU'UN SERRE-ECROU.THE INVENTION RELATES TO A MECHANISM FOR STOPPING THE MOTOR OF A FLUID TOOL, AS A FUNCTION OF THE SPEED. THIS MECHANISM INCLUDES A MEANS 38, 40 CONSTITUTING A FLUID OUTLET DUCT, CONDUCTED IN THE BODY 32 OF THE TOOL 10 AND BY WHICH THIS FLUID LEAVES THE MOTOR 14. A SHUTTER 66 CAN BE PUT IN AN OPENING POSITION, FOR ALLOW THE EXHAUST FLUID AUDIT TO GO THROUGH THE DUCT, AND CLOSE, IN WHICH IT BLOCKS ITS FLUID AND STOPS THE ENGINE. A MEDIUM 64, 72, SENSITIVE TO THE DECREASE IN THE SPEED OF THE ENGINE 14, TAKES THE SHUTTER 66 TO ITS CLOSED POSITION. APPLICATION TO PNEUMATIC TOOLS, SUCH AS A NUT CLAMP.
