SOLENOID VALVE DRIVING CONTROL APPARATUS AND SOLENOID VALVE PROVIDED WITH SOLENOID VALVE DRIVING CONTROL APPARATUS

摘要

(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 adsorbed 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 72, after energizing of zero cross timing to the solenoid 66 is started by the switching device 68, when the current value that flows to the solenoid 66 detected by the electric current sensing device 78 is reached to the circuit protection current value Ic (±A), a stabilization mode that repeats the ON-OFF cycle plural times (four times of the total in the Embodiment of Fig. 4 ), in which energizing to the solenoid 66 is intercepted by the switching means 84, is operated (see A5-A8 in Fig. 4 ).
