Abstract

PURPOSE:To reduce impact force generated when an armature abuts against a stopper, by cutting off energizing electrical current in a predetermined time period after the armature is displaced by applying the energizing electrical current to a driving coil in an initial driving period. CONSTITUTION:An energizing current controlling circuit for a drive coil 5 in a solenoid valve 1 supplies, in its switch instructing stage CA, energizing electrical current (i) to the driving coil 5 in a time period tau1 when on-off instuctions EV for the solenoid valve 1 having a low voltage level switching instruction stage CA and a high voltage level returning instruction stage CB next thereto, is delivered, then interrupts the energizing electrical current (i) in a time period tau2 and further reapplies the energizing electrical current (i) to the driving coil 5 in a time period tau3 following to the time period tau2.
