ABSTRACT:
Multiple stacked orifice disk members cooperatively form a chamber space through which fuel is constrained to pass as it flows from the valve seat to the nozzle. Orifices in one member that communicate the chamber space to the fuel flow are larger and perform primarily a turbulent flow creating function while orifices in another member that communicate the chamber space to the fuel flow are smaller and perform primarily a metering and targeting function. Thus, turbulence and metering functions are segregated from each other. In certain embodiments at least one more orifice disk member is sandwiched between the first two to divide the chamber space in one or more smaller chamber portions while still providing fluid communication between such portions, such added disk member(s) contributing either one or both functions of turbulence or better metering and targeting. In certain embodiments, all orifices are equal so that each contributes to turbulence, metering, and targeting.
