Abstract
PURPOSE: To omit a resistor, a switch, etc., and to obviate the wasteful consumption of electric power, by driving an electromagnetic valve through a plurality of pulsated electric currents.
CONSTITUTION: In a series circuit containing an electric source terminal 1, an electromagnetic valve 2 and an electromagnetic valve controlling means 5, the controlling means 5 is connected to a series circuit containing an input terminal 6, a function generating means 7 and a pulse width modulating means 8. When a valve opening signal (a) is sent to the input terminal 6, the function generating means 7 actuated to generate a signal (b) whose pulse width is modulated at the pulse width modulating means 8 that in turn outputs a signal (c). The electromagnetic valve 2 is driven by this pulse voltage signal (c) via the electromagnetic controlling means 5. Accordingly, a resistor, a switch, etc. are omitted, and the consumption of electric power is reduced.
