Patent ID: 7784282

Claim:
A fuel injector comprising: a nozzle comprising an outlet orifice having a first diameter; a cooling assembly comprising: a first fluid transfer line in flow communication with a first cooling coil; and a second fluid transfer line in flow communication with a second cooling coil, at least one of said first cooling coil and said second cooling coil circumscribing a portion of said fuel injector; and a tip coupled to said nozzle, said tip comprising: a base comprising: a cooling channel defined therein by a substantially cylindrical outer wall and a frustoconical inner wall; an inner surface that circumscribes said nozzle outlet orifice, said inner surface having a second diameter that is smaller than said outlet orifice first diameter, said base sized to receive said nozzle therein; and an outer surface; a first transition member in flow communication with said cooling channel and said first fluid transfer line; and a second transition member in flow communication with said cooling channel and said second fluid transfer line, wherein said base, said first transition member, and said second transition member are formed integrally together, each of said first transition member and said second transition member extend outward from said base outer surface, and each comprises a first end, a second end, and a body extending therebetween, each of said transition member first end is coupled to said base outer surface such that each of said first transition member body and said second transition member body extend outward therefrom, said tip configured to couple to said cooling assembly to channel a flow of cooling fluid through said cooling channel via said first transition member and said second transition member.
