Abstract

See full text

An orifice plate used as part of a fuel injector. The orifice plate has a base portion, an offset portion integrally formed with the base portion, a flow entry side and a flow exit side, where the base portion and the offset portion are part of the flow entry side and the flow exit side. A plurality of exit apertures is integrally formed with the offset portion. Each of the plurality of exit apertures includes a plurality of stepped portions, and at least one inner diameter, and each exit aperture is disposed at an angle relative to a central axis extending through the orifice plate. Each exit aperture is of a depth that is about twice the size of the inner diameter, providing optimal atomization of the fluid as the fluid flows through the exit apertures.
