Title
(EN) REGENERATION SYSTEM AND METHOD OF ENERGY RELEASED FROM WORKING IMPLEMENT
(FR) SYSTÈME DE RÉGÉNÉRATION ET PROCÉDÉ DE LIBÉRATION D'ÉNERGIE À PARTIR D'UN OUTIL DE TRAVAIL
Abstract
(EN)
An embodiment of the present invention provides a regeneration system of energy released from a working implement, which includes an actuator configured to move up and down the working implement, an accumulator configured to communicate with the actuator, and a controller configured to receive a pressure value of the actuator and a pressure value of the accumulator to control a discharge operation of the accumulator based on a pressure difference value between the actuator and the accumulator.
(FR)
Un mode de réalisation de la présente invention concerne un système de régénération d'énergie libérée à partir d'un outil de travail, qui comprend un actionneur configuré pour déplacer vers le haut et vers le bas l'outil de travail, un accumulateur configuré pour communiquer avec l'actionneur, et un dispositif de commande configuré pour recevoir une valeur de pression de l'actionneur et une valeur de pression de l'accumulateur pour commander une opération de décharge de l'accumulateur sur la base d'une valeur de différence de pression entre l'actionneur et l'accumulateur.
