Abstract

PURPOSE: To make a flow delivery of the pump constantly keepable even for a change caused in input voltage or electric resistance of the solenoid coil, by directly detecting an integral value of current, flowing in the solenoid coil, till it reaches the maximum current, to control constantly.
CONSTITUTION: By aiming the fact that a flow delivery of the solenoid pump be approximately proportional to an integral value of current, flowing in a solenoid coil 2, till it reaches the maximum value, the constitution is made such that with a value of current in a wire 3a detected by a voltage value, a value integrated by an integrating circuit 6 is directly detected to be compared with the reference value in a signal line 7a, determining a drive time of the solenoid coil 2. In this way, even though DC voltage applied to an input terminal 1 is unstable and a value of electric resistance of the solenoid coil is varied, a flow delevery from the solenoid coil becomes capable to be kept constant.
