Abstract
Disclosed herein is a solenoid valve driving device having at least two solenoid valves arranged in adjacent relationship. Magnetic fluxes generated in adjacent solenoids of the solenoid valves upon energization thereof are opposite in direction to each other. Accordingly, when the adjacent solenoids are simultaneously energized, a common magnetic circuit between these solenoids is generated to result in an increase in magnetic flux, thereby increasing a magnetic attraction force of each solenoid. Thus, the solenoid valve driving device can sufficiently ensure the magnetic attraction force of each solenoid and can achieve size reduction and power saving.
