<p>A device for driving a solenoid valve having a drive circuit that controls an exciting current for opening/closing a plurality of valve elements and can be constituted of a small number of switching means. The valve elements are grouped into valve element groups each composed of two valve elements and the drive circuit is provided so as to drive each valve element group. The drive circuit is composed of three serial circuits constituted by connecting three switching means in series between a high-voltage side first power supply terminal and a low-voltage side second power supply terminal. Four electromagnets corresponding to the valve element groups connect serial connecting sections among the switching means by means of the different serial circuits.</p> |
