Abstract

(Problem) The invention is to provide to a solenoid valve drive control device, in which though the magnetic path is normally composed (i.e. the plunger is attached to the attracting member), it is never determined by mistake as the dropout, and it is never entered into the reabsorption mode of the plunger. (Resolution Approach) The invention is a solenoid valve drive control device of the invention, in which by controlling of the zero cross timing generation device, after application of the electric current to the solenoidis started at zero cross timing by the switching device, when the current value that flows to the solenoiddetected by the electric current sensing devicereaches the circuit protection electric current value Ic (αA), a stabilization mode that repeats the ON-OFF cycle plural times (four times of the total in the Embodiment of FIG.), in which application of the electric current to the solenoidis interrupted by the switching means, is operated (see A-Ain FIG.).
