The injector has a hollow body housing the body of the metering valve, which has a discharge hole for discharging the usual control chamber. The hole comes out at a flat surface of the valve body, and is engaged by a flat surface of a plate, under the control of an armature of an electromagnet. The armature is in the form of a disk, has substantially no stem, is connected to the hollow body by a leaf spring hinge, and has a surface having a spherical-bowl-shaped recess. A ball is located between the recess and another recess carried by a second surface of the plate. The valve body is fixed to the hollow body by a ring nut of a given height. And, to cover the distance between the valve body and the armature, a spacer member is preferably formed in one piece with the valve body.
