Abstract: PURPOSE: To improve action of an injection valve by axially interposing a floating annular element between armature and body of a metering valve, and covering only a part of the annular element that is opposite to the armature and the body. CONSTITUTION: A floating annular element 14 is axially interposed between an armature 13 and body 10a of solenoid valve 10, only a part of the annular element 14 that is opposite to the armature 13 and the body 10a is covered. While an obturator 11 is at the position to close a discharge hole during working of the valve, as the needle 4 is placed at lower position, so the pressurized fuel in the injection chamber 6 does not flow to the nozzle 3. And while the discharge hole is opened by the obturator 11 of the valve 10, pressure of the control chamber 9 is reduced and the needle 4 is raised, the pressurized fuel in the injection chamber 6 is injected from the nozzle 3.  Because a non-magnetic material annular element 14 exists, attachment of the armature 13 on the magnetic core of the valve 10 is prevented, time delay of action of the obturator 11 from open position to close position disappears.
