Abstract: A compressor housing having an integrally formed throat, such as is used on internal combustion engines and specifically diesel engines, may be repaired or modified by removal of the throat portion and replacement of that portion with a separate throat insert selected from a variety of throat inserts for a given size compressor housing and for various specifications.

Abstract: A compressor housing (30) is disclosed of the type characterized by having a centrally-disposed, concentric, flow restricting inlet throat in fluid communication with an encircling fluid conduit having a tangentially disposed outlet. Compressor housing (30) includes a separately formed inlet throat insert (45) for being positioned in a bore (29) in compressor housing (30). Insert (45) can be removed if damaged, or if a change in inlet throat size is desired.

Abstract: A top stop-type fuel injector (10") for an internal combustion engine is disclosed. A pressure-time-delivery injector body (11"), barrel (12") and cup (13") are positioned in end-to-end relation. A retainer (14") extends around the barrel and secures the barrel (12") and cup (13") to the injector body (11"). A plunger (25") is positioned for restrictive movement within a plunger bore (24"). A return spring (29") is mounted within the upper end of the injector body (11") in concentric relation to the plunger (25"). A portion of the upper end of the injector body (11") is cut away to provide more room for adjustment of the injector (10"). External threads (80A) are formed on the remaining upper end of the injector body (11") adjacent the free end thereof. A collar (82) having mating internal threads (81) is mounted on the upper end of the injector body ( 11").
