Electromagnetic valve actuator device

Abstract

An excitation control device performs a peak current drive, in which a peak current is injected into a coil to move a movable core from a valve closing state into a valve opening direction and cause the movable core to hit a stop, and a pull-back current drive, in which, following the peak current drive, a pull-back current is injected into the coil to pull the movable core back into the valve opening direction during a movement period of a valve part due to rebound of the same, after the movable core being moved in the valve opening direction has hit the stop, and the pull-back current in a second injection mode is greater than the pull-back current in a first injection mode.
