Abstract
An electromagnetically operated valve for injecting fluid comprises first guiding element connected to one end portion of a stationary iron core and containing a movable core slidably therein for guiding a movement of a movable valve connected to the movable core, and second guiding element for slidably guiding the movable valve in a position between a large-diameter portion and a seat portion of the movable valve. According to such fluid injection valve, as the movable core and movable valve are axially guided by first guiding means and second guiding element in the above respective positions, the wear of the stopper portion of the movable valve is lessened due to the outer force to the movable valve.
