Abstract
A fuel supply apparatus includes a movable unit, a coil, a drive circuit portion, and a drive control portion. The drive circuit portion energizes the coil with a drive electric current of a first value such that the movable unit is displaced from an opening-side position to a closing-side position. The drive circuit portion energizes the coil with the drive electric current of a second value that is smaller than the first value such that the movable unit is held at the closing-side position. The drive control portion controls the drive circuit portion to change the drive electric current from the first value to the second value while the movable unit is being displaced toward the closing-side position based on energization of the coil with the drive electric current of the first value.
