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

摘要

The valve of the invention substantially comprises a metal body (1) in which is housed an electromagnet (2) and a core (3) disposed within it as well as an injection nozzle (6) provided with at least one fuel injection orifice (9) the passage through which is controlled by a movable shutter member (15) fixed to an armature (16) and adapted to control the passage of fuel through the said injection orifice; according to the invention the shutter member (15) is constituted by a disc (10) delimited by a cylindrical outer lateral surface (17) which has substantially the same diameter as the outer surface of the armature, and by a pair of upper and lower flat circular surfaces (22, 23) and is connected to the said armature by laser welding (25) formed between the upper circular edge of the disc and the lower circular edge of the armature.
