ABSTRACT:
A valve-closed-orifice (VCO) spray tip having an internal tip seat and one or more fuel spray orifices. The thickness of the tip in the wall portion defining the internal tip seat and upstream entrance of each orifice is made less than that of previously known VCO tips. The length to diameter ratio of each orifice is also relatively smaller than that of previously known VCO tips. Advantages of the thinner wall portion include improved fuel injection spray characteristics as well as reduced cost of forming orifices through the tip.
