油を阻止するように逆止弁を各余剰ポートに対し
て設けたことを特徴とする分流弁装置。 An input port to which a hydraulic pump is connected, a diversion port to which a certain amount of the pressure oil supplied to the input port is preferentially diverted, and a surplus port from which excess pressure oil flows out, and the input port is connected to the diversion port. Two flow divider valves whose flow rate is compensated by the operation of the spools are provided such that both ends of the respective spools are opposed to each other, and both ends of the opposing spools are fitted through a spring chamber into which a flow divider port is opened. In a flow divider valve device in which springs are installed in series and the spools of the two flow divider valves come into contact with the spring chambers, pressure oil flows freely from the input port side to the surplus port side and is inputted from the surplus port side. A flow dividing valve device characterized in that a check valve is provided for each surplus port so as to prevent pressure oil from flowing toward the port side.
