<P>PROBLEM TO BE SOLVED: To constitute a control device which suppresses an impact caused by the abutment of a plunger against a stopper when shutting off a driving current supplied to an electromagnetic solenoid. <P>SOLUTION: An electrical power control portion B which supplies the driving current to the electromagnetic solenoid Vs performs the control of a normal drive mode supplying the driving current by setting a first setting value F1 to a desired current value when moving the plunger to a target position. Next, the electrical power control portion B performs the control of a holding mode supplying the driving current by setting a second setting value F2 which is configured as a value which is lower than the first setting value F1 and with which the plunger does not abut against the stopper when restoring the plunger to a position abutting on the stopper and subsequently, performs the control of a sweep drive mode which reduces the desired current value step by step. <P>COPYRIGHT: (C)2013,JPO&INPIT |
