ELECTROMAGNETIC INJECTOR FOR INTERNAL COMBUSTION ENGINE Russian patent published in 1999 - IPC

FIELD: manufacture of internal combustion engines, specifically, fuel-injecting devices with electron control over gasoline engine. SUBSTANCE: proposed electromagnetic injector includes atomizer composed of body with seat transferring to nozzle aperture, shut-off needle positioned in its axial hole and electromagnetic coil. Immobile core and armature pressed on to tail part of shut-off needle which travel is limited by resting of its butt against distance piece pressed against bearing butt of atomizer body are located inside electromagnetic coil. Axial hole of atomizer body is through one that has insert incorporating seat and nozzle aperture. Travel of shut-off needle is limited by depth of installation of insert which fairing is welded. EFFECT: high adaptability of invention to manufacture, ensured high functional qualities of electromagnetic injector. 2 dwg
