Abstract

PURPOSE:To make large the width of pulsation in current by adopting a drive system in which the current shall vary in compliance with the duty ratio of the pulsation in such a way that the period of pulsation is short when the duty ratio is small and long when it is large. CONSTITUTION:Voltage signal and the input signal Vs are placed in a differential amplifier circuit 65. Accordingly, a rapid response voltage in compliance with the change is placed out at the ouput terminal of this circuit 65 even though the input signal Vs changes. If, in a comparator circuit 66, the ouput voltage of the differenctial amplifier circuit 65 is fed into the positive terminal and the triaangle wave generated at the ends of a capacitor 55, into the negative terminal, a repeated pulsation is obtained whose duty ratio becomes large with increasing voltage level of the input signal Vs. This pulsation is amplified by an amplifier circuit 67 so that energization by a solenoid 11 can give a current enoght to drive the solenoid-operated proportinal flow control valve V.
