Abstract:
Provided is a direct spray fuel injector including a bundle of opening/closing valves, wherein the bundle of opening/closing valves includes: a valve needle that is disposed within a valve housing; an electromagnetic coil that is installed at a side opposite to the spray hole of the valve needle; an armature that is coaxially mounted on an outer circumferential surface of the valve needle to be slidable in an axial direction; and a pressurizing spring that is installed to pressurize the valve needle toward the spray hole and causes the valve needle to close the spray hole in normal times, and the bundle of opening closing valves is configured to pressurize the valve needle by the armature so that bounce generated when the valve needle in an open state approaches the spray hole so as to close the spray hole is able to be attenuated.
