ABSTRACT:
A solenoid-operated valve actuating controller actuates a solenoid-operated valve by energizing an actuating coil of the solenoid-operated valve in a rated mode, enough to move a movable member in the actuating coil, during a first period. Further, the actuating coil is energized in a power saving mode, during a second period after the first period. The solenoid-operated valve actuating controller has a timer circuit for setting the first period, an oscillating circuit for energizing the actuating coil in the power saving mode during the second period, and a control circuit for stopping an oscillating operation of the oscillating circuit during the first period based on an output signal from the timer circuit, and for energizing the actuating coil in the rated mode.
