Abstract
An electromagnetically-controlled fuel injection valve for diesel engines includes a body carrying an upper electromagnetic metering valve including a body carrying an excitation coil and an obturator carried by an armature and adapted to control communication between the control chamber of the injection valve and a fuel discharge hole. A floating annular element of non-magnetic material is interposed axially between the armature and the body of the metering valve.
