Abstract
A fuel injection valve for fuel injection systems of internal combustion engines, in particular for direct injection of fuel into a combustion chamber of an internal combustion engine, has a magnet coil, an armature that can be moved by the magnet coil in a linear stroke direction toward a first return spring, and a valve needle joined to a valve closure element. In the linear stroke direction, the armature engages positively on the valve needle. In the opposite direction, the armature is freely movable independently of the valve needle toward a second return spring. The armature is bearing-mounted on the valve needle by way of at least one slide bearing having several balls.
