ABSTRACT:
A high pressure vortex fuel injector comprising a hollow housing or body including a plurality of passages at least one of which is adapted to receive fuel through an inlet. The injector also includes a passage for guiding the piston into seating relationship with the valve seat to control the flow of fuel through the metering orifice and a solonoid assembly for moving the piston relative to the valve seat. The injector further includes a swirl or vortex chamber, to angularly accelerate the fuel, formed in cooperation with the first surface of the valve seat. The injector additionally includes passages for permitting fuel to circulate about an electric coil thereof, thereby cooling same during instances when the metering orifice is closed. The injector further includes passages within the swirl chamber for assisting in the rapid formation of a conical spray pattern upon the opening of the metering orifice.
