Claims

[Claims for Utility Model Registration] 8(1) An inlet connected to a high pressure source, an outlet connected to a tank, and first and second output ports for obtaining a target output pressure are provided, and the first and second output ports are provided. First and second artificial valves, which are electromagnetic on-off valves, are interposed between the second output port and the inlet, respectively, and an outlet valve, which is an electromagnetic on-off valve, is interposed between the first and second output ports and the outlet. In the proportional control valve, the outlet valve is provided with first and second valve holes communicating with the first and second output ports, and the first and second valve holes are respectively provided between the two valve holes.
and a spring interposed between a movable core having a second valve portion and applying a force to the movable core to press one of the valve holes in the valve closing direction, and a spring that offsets the pressing force of the spring to press one of the valve holes. 1. A proportional control valve comprising an electromagnetic coil that applies an electromagnetic force in the direction of opening one valve hole and closing the other valve hole. (2) Insert a part of the passage extension member that communicates with the first output port into the inner periphery of the fixed core of the electromagnetic on-off valve that constitutes the outlet valve, and insert the first valve hole into the tip of the passage extension member. The proportional control valve according to claim 1 of the utility model registration claim, characterized in that the proportional control valve is provided in the section. (3) A request for registration of a utility model characterized in that a required pressure difference is provided between the balance pressures of the first population valve and the exit valve and the second population valve and the exit valve so that the exit valve side is lower. The proportional control valve according to the range 1 or 2.
