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, which is biased by a first springbiasing in a valve closing direction, as a movable element which opens and closes a valve when being attracted by a magnetic coreof the electromagnetic fuel injection valve; and a second movable elementbiased toward the magnetic coreby a second springbiasing in a valve opening direction.
