Abstract

La présente invention concerne un circuit de commande (4) d'un vérin double effet (2), le vérin double effet comportant une tige (6) montée en translation dans un corps (8), deux chambres (10, 12), et un moyen (14) de positionnement électronique de la tige dans le corps. Le circuit de commande est configuré pour commander un parcours (T) du vérin entre deux positions déterminées (A, B) en alimentant en fluide sous pression la deuxième chambre (10) pour faire passer le vérin de la première position déterminée (A) à une position intermédiaire (C), puis en alimentant en fluide sous pression la première chambre (12) pour faire passer le vérin de la position intermédiaire (C) à la deuxième position déterminée (B). Le circuit de commande comporte également une entrée destinée à recevoir des données d'un capteur de pression (24) du fluide dans la première chambre (10), et le circuit de commande est configuré pour détecter la position intermédiaire (C) du vérin lorsque les données fournies par le capteur de pression (24) indiquent une pression en-dessous d'une valeur déterminée. L'invention concerne également un circuit hydraulique (1), un dispositif agricole et un engin agricole comportant un tel circuit de commande.The present invention relates to a control circuit (4) of a double-acting cylinder (2), the double-acting cylinder comprising a rod (6) mounted in translation in a body (8), two chambers (10, 12), and means (14) for electronic positioning of the rod in the body. The control circuit is configured to control a path (T) of the jack between two determined positions (A, B) by supplying pressurized fluid to the second chamber (10) to cause the jack to pass from the first determined position (A) to an intermediate position (C), then by supplying pressurized fluid to the first chamber (12) to move the actuator from the intermediate position (C) to the second determined position (B). The control circuit also has an input intended to receive data from a pressure sensor (24) of the fluid in the first chamber (10), and the control circuit is configured to detect the intermediate position (C) of the jack when the data supplied by the pressure sensor (24) indicates a pressure below a determined value. The invention also relates to a hydraulic circuit (1), an agricultural device and an agricultural machine comprising such a control circuit.
