路。[Claims for Utility Model Registration] A flow control valve and a direction control valve are connected to a main passage connecting a main pump and a steering cylinder, and the flow control valve has the following features: 1. Maintain a position where the forces in the pilot chambers on both sides are balanced, and at this position set the control flow rate supplied to the directional control valve and the surplus flow rate supplied to other work equipment side circuits, and orbit roll. By this operation, the pilot pressure is guided to the pilot chamber of the directional control valve to switch the directional control valve in a predetermined direction, and a stop valve is provided in the passage leading to the pilot chamber. Before hitting the stopper,
The above-mentioned stop valve switches to cut off the supply flow path of the above-mentioned pressure. A steering circuit that forms a passage that leads the pilot chamber of the flow control valve to the tank.
