Abstract

Dispositif d'entraínement de l'arbre porte-clef d'une machine à tirefonner dans lequel la source énergétique entraíne une pompe alimentant deux moteurs (4 et 5) hydrauliques montés en dérivation et comportant des moyens pour alimenter l'un des moteurs ou les deux à la fois et une vanne (19), normalement fermée, interposée dans le circuit d'alimentation d'un moteur et dont l'ouverture est commandée par la pression du fluide hydraulique lorsque celle-ci atteint une valeur prédéterminée, ledit fluide repous­ sant un piston soumis à l'action d'un ressort antagoniste, la section dudit piston (23) étant telle que la vanne reste ouverte même si lors du couplage du second moteur (5) la pression dans le circuit tombe à une valeur inférieure à celle qui devrait régler à cet instant. Un limiteur de pression (25) est interposé dans le circuit et permet de dériver le fluide sous pression vers le réservoir (6) lorsque la pression à l'entrée dudit limiteur atteint une valeur qui correspond au couple de serrage désiré. Device for driving the key-holder shaft of a threading machine in which the energy source drives a pump supplying two motors (4 and 5) hydraulic mounted in diversion and comprising means for supplying one or both motors at the same time and a valve (19), normally closed, interposed in the motor supply circuit and whose opening is controlled by hydraulic fluid pressure when this reaches a predetermined value, said fluid repels sant a piston subjected to the action of an antagonistic spring, the section of said piston (23) being such that the valve remains open even if during coupling of the second motor (5) the pressure in the circuit drops to a value lower than that who should settle right now. A pressure relief valve (25) is interposed in the circuit and allows the fluid to be diverted under pressure to the tank (6) when the pressure at the input of said limiter reaches a value which corresponds to desired tightening torque.
