Abstract
PURPOSE: To obtain a readily controllable by making frequency adjustment and pulse with adjustment performable at one place by composed output of operational amplifiers.
CONSTITUTION: Coil P of an electromagnetic pump in the pump conduction circuit 30 is driven by electric current controlled by conducting direct current from the power supply part 10 by thyristors SCR1, SCR2. And in order to control frequency and pulse width in driving current, conduction and non-conduction of SCR1, SCR2 are controlled by charging and discharging capacitors C2, C5. The cycle of these charge and discharge is controlled by a fuel supply amount manual adjusting circuit 50 equipped with variable resistor VR1 and operational amplifiers OP1, OP2. And the operational OP1 outputs signal in the same polarity with the settled amount by taking reference potential by resistors R1, R2 and settled amount by VR1, as input, the operational amplifier OP2 works so that it may output the settled amount and signal in the inverse polarity to the settled amount by taking reference potential and output of the operational amplifier OP1 as input.
