Abstract
PURPOSE: To obtain output and input characteristics at optional value, by constituting a path bypassing the control valves providing, in the middle of the path of fluid, the control valves and the orofices changing the cross section area by the output shaft of the porportional electromagnetic valve.
CONSTITUTION: The proportional electromagnetic valve 6 is constituted with the cylindrical coil 3 provided between the case 1 and the core 2, and the output shaft 5 fixed at the plunger 4 placed in the core 2, while the flow control valve 7 is constituted with the orifices 9 provided in the middle of the control path of fluid 8, and the control valves 10 provided in the orifices 9 to change the cross section area. The path 11 is equipped to bypass the orifices 9 to the path of the control valves 10. Also, in the case where the necessity to stably control the bypass flow arises, the jet 12 is installed in the path of bypass.
