ELECTROMAGNETIC FUEL INJECTION VALVE

摘要

PROBLEM TO BE SOLVED: To achieve both of improvement of responsiveness and improvement of operation stability by allowing a movable element to perform idle running motion before starting operation of a valve body during both operations of valve opening and valve closing in an electromagnetic fuel injection valve and suppressing bound operation of the movable element which may be generated during valve opening operation.SOLUTION: The electromagnetic fuel injection valve includes a first movable element 105 energized by a first spring 106 for energizing the movable element in a valve closing direction as a movable element sucked by a magnetic core 109 of the electromagnetic fuel injection valve to open/close the valve and a second movable element 104 energized in a direction of the magnetic core 109 by a second spring 112 for energizing the movable element in a valve opening direction.
