Abstract: A fuel inlet assembly for a fuel injection valve comprises a coil bobbin having at least one terminal insulating post extending axially through a radial flange on the inlet connector. The post has an axial terminal slot therein to receive a thin section of a terminal and comprises a welding-and-dimple aperture directly over the terminal slot ending in a radial dimple locking wall thereover. The terminal comprises a dimple across substantially the entire narrow width thereof, the dimple cooperating with the dimple locking wall after the terminal is inserted into the terminal slot to retain the terminal therein.

Abstract: A low-cost precise-metering uniform-fuel-breakup fuel injection valve comprises narrow arcuate slots etched through a thin spray disc located downstream of a metering orifice and comprises a plurality of narrow slots of length and width sufficient to break up the fuel first into thin sheets and then into small droplets of uniform diameter.

Abstract: A low-cost precise-metering uniform-fuel-breakup fuel injection valve comprises narrow arcuate slots etched through a thin spray disc located downstream of a metering orifice and upstream thereof comprises a ball seat for providing a circular edge contact with a slightly smaller ball valve carried on the free end of a flexible stem. The fixed end of the stem is secured within a loosely supported armature having a central passage telescoping a substantial length of the flexible stem and inducing a smooth central fuel flow towards the ball valve and seat.
