Abstract

PURPOSE: To make it possible to control the drive regardless of, and corresponding to, power supply voltage variation, temperature change and coil manufacturing errors, by supplying current from the power source after the current flowing in a solenoid coil reached the reference current value until the preset time.
CONSTITUTION: Solenoid coil S in the solenoid pump is driven and controlled by means of a bridge circuit consisting of diodes D1WD4, smoothing circuit 1 including smoothing condenser C1, rectangular waveform oscillator 2 including calculator- amplifier IC1, voltage compensator 3 including temperature compensator 4, and constant current control circuit 6 including hysteresis circuit 5. That is, the current flowing in coil S is controlled by a voltage signal having a pulse width. The preset time from the time when the current attained the reference current value is calculated, and the pulse width output is made to disappear when the preset time has elapsed.
