Abstract: A fuel injector for supplying fuel to a fuel consuming devise includes a fuel inlet for receiving the fuel, a nozzle tip for dispensing the fuel from the fuel injector, a conduit for communicating the fuel from the fuel inlet to the nozzle tip, a valve seat, and a valve selectively seatable and unseatable with the valve seat for selectively preventing and permitting fuel flow out of the nozzle tip. The nozzle tip includes a non-circular recess on a downstream side thereof and a metering hole on an upstream side thereof opening into the non-circular recess to allow fuel to exit the nozzle tip, the metering hole having a smaller area than the non-circular recess.
