Title (EN) DEVICE FOR FEEDING A HIGH FREQUENCY OSCILLATING TOOL
(FR) DISPOSITIF D'ALIMENTATION D'UN OUTIL OSCILLANT A HAUTE FREQUENCE
Abstract:
(EN) The invention relates to a device for driving a high-frequency oscillating tool arrangement (1) which includes, inter alia, a device (1a) whose form changes with a change in voltage, utilizing an electric drive circuit (2) constructed to generate alternating voltage, which can be connected to the device. The current and/or voltage connected to the arrangement (1) is fed in different energy modes or states, a high energy state during operation of the tool and a low energy state, intended as a ''stand-by'' function.
(FR) Dispositif de commande d'un agencement (1) d'outil oscillant à haute fréquence, comprenant entre autres un dispositif (1a) dont la forme change avec un changement de tension, utilisant un circuit d'attaque électrique construit pour produire une tension alternative pouvant être connectée au dispositif. Le courant et/ou la tension connectée à l'agencement (1) est alimenté dans différents modes ou états d'énergie, un état de haute énergie pendant le fonctionnement de l'outil, et un état de basse énergie destiné à une fonction ''attente''.
