Abstract
A fuel injector nozzle assembly includes an injector body including a valve seat with a supply passage through which fuel flows generally along a supply axis. A nozzle plate having a top surface and a bottom surface is mounted onto the valve seat. The top surface includes a recess formed therein whereby fuel flows into the recess from the supply passage. A plurality of swirl chambers are formed within the top surface, each having a conical orifice extending from the swirl chamber to the bottom surface of the nozzle plate. A plurality of channels interconnect each of the swirl chambers to the recess, wherein the channels meet the swirl chambers offset from a center of the swirl chambers.
