ELECTROMAGNETICALLY OPERATED FUEL INJECTION VALVE

摘要

ELECTROMAGNETICALLY OPERATED FUEL INJECTION VALVE 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.
