Abstract

La présente invention concerne l'alimentation d'une quantité désirée de fluide hydraulique requise par un appareil en option (4) dans le cas où un travail combiné est effectué par coopération d'un appareil en option avec un appareil de travail. On prévoit un circuit hydraulique pour un appareil en option (4) d'équipement lourd utilisant un tiroir de confluence de flèche (14), comprenant un distributeur à clapet (13) installé dans un trajet d'écoulement d'un côté d'alimentation d'un tiroir pour l'appareil en option, un tiroir de confluence de flèche qui commande le débit fourni à l'appareil en option (4) et à l'appareil de travail et installé directement en amont du tiroir de l'appareil en option (4), une seconde soupape électromagnétique de réduction proportionnelle qui est placée dans un trajet d'écoulement entre la pompe de pilotage et le tiroir de confluence de flèche (14) et générant en sortie une pression secondaire en réponse à un signal électrique fournir par l'unité de commande et commandant le tiroir de confluence de flèche (14), et un premier tiroir (15) placé en aval du distributeur à clapet (13) et commuté lorsqu'une différence de pression entre le côté amont et le côté aval du tiroir de confluence de flèche est supérieure à une valeur de réglage et possédant une fonction pouvant réduire un degré d'ouverture du distributeur à clapet (13).
