Abstract
Provided is an electromagnetic fuel injection valve in which in both operations of opening and closing a valve, a movable element is made to free run before a valve element starts to operate, and bounding motion of the movable element occurring at the time of the valve opening operation is reduced, thereby balancing improvement of responsiveness and improvement of stability of operation. There are equipped with: a first movable element 105, which is biased by a first spring 106 biasing in a valve closing direction, as a movable element which opens and closes a valve when being attracted by a magnetic core 109 of the electromagnetic fuel injection valve; and a second movable element 104 biased toward the magnetic core 109 by a second spring 112 biasing in a valve opening direction.
