Abstract
PURPOSE: To discriminate an operating condition of a solenoid valve by a method wherein there are provided a solenoid valve for use in opening or closing the valve and a vibration sensor for use in sensing a vibration caused by the movement of a plunger.
CONSTITUTION: A signal is applied to an amplifier 22 through an input terminal 21 of signal processing circuit. Only a high frequency signal is taken out through and then supplied to a fast charging and gradual discharging circuit 25. When the signal is set at "1" level, a capacitor 26 in the circuit 25 is rapidly charged through the diode 27, and in turn when the level is "0", a charging load of the capacitor 26 is discharged gradually through the resistor 28 in respect to a charging time. The output signal from the second comparator circuit 29 is supplied to AND gates 30 and 31. Valve driving signal 11 is directly supplied to AND gate 30 from the terminal 32 and the signal is supplied to AND gate 31.
