Abstract
PURPOSE: To remarkably improve the set pressure accuracy and the linearity to the solenoid driving current, by feeding back the position signal of the moving valve seat to the control section and controlling the position of plunger.
CONSTITUTION: The position of the plunger 12 of the solenoid 9 driving the moving valve seat 2 is detected by the potentiometer 11, and the position signal eS is fed to the inverting amplifier 13. Further, the output signal eS1 of the amplifier 13 is added with the objective signal eO input from the input terminal 15 at the amplifier OA2 of the proportional and integral network 14 and integrated. The output eO1 is added with the objective signal eO branched at the feed forward line 16, at the addition circuit 17, and the output eO2 is given to the main amplifier 18. Further, the output signal of the amplifier 18 is fed back to the solenoid 9 for control. Thus, without being disturbed by external disturbance, the set pressure accuracy and the linearity to the solenoid driving current can remarkably be increased.
