Abstract
PURPOSE: To provide the controlled flow not to be influenced by negative pressure, by constituting the plural valves controlled by the proportional electromagnetic driven controller change cross section area of the orifices to actuate together by the mechanical output of the proportional electromagnetic driven controller.
CONSTITUTION: The proportional electromagnetic driven controller 1 is constituted as main components of the cylindrical coil 2, the core 3 equipped inside the coil, plunger 4, and the output shaft 5 fastened to the plunger 4, while the flow control valve 6 is constituted as main components of the path of fluid 7, the plural orifices 8, 9 provided in the middle of the path of fluid 7, and the plural valves 10, 11 changing the cross section area of the orifices 8, 9. And the shaft 5 and the valves 10, 11 are connected mechanically so that the valves 10, 11 are operated actuating together by the mechanical output of the shaft 5. Also, each of the valves 10, 11 is arranged to face each other along and against the direction of the flow of the fluid so that the negative pressure to be generated in the front and at the back of each valve is offset.
