Fast solenoid valve, particularly a fuel injection pilot valve for diesel engines.

摘要

An electromagnetically-controlled fuel injection valve for diesel engines includes a body (2) having an upper electromagnetic metering valve (10) including an obturator (11) supported by an armature (13) and controlling communication between a control chamber (9) and a fuel discharge port (A). A series of radial notches (14) which may be empty or filled with an insulating material is formed in the armature (13).
