Electromagnetically actuated fuel atomising and metering valve for a heat engine fuel supply device

摘要

The present invention involves an electromagnetically actuated fuel atomizing and metering valve. The valve has a metal body housing an electromagnet, a core, and an injection nozzle. The injection nozzle has at least one fuel injection orifice passage controlled by a movable shutter member fixed to an armature. The shutter member controls the passage of fuel through the injection orifice and comprises a disc delimited by a cylindrical outer lateral surface which has substantially the same diameter as the outer surface of the armature. The disc is connected to the armature by laser welding between the upper circular edge of the disc and the lower circular edge of the armature.
