Abstract
A multi-point injector includes an annular body defining an interior annular flow passage. The annular body includes a fluid inlet and a plurality of circumferentially spaced apart fluid outlets in fluid communication with the interior flow passage. Each of the outlets has a swirl chamber formed within the annular body associated therewith for imparting swirl to fluid delivered thereto.
Claims20
A multi-point injector comprising:
- an annular body defining an interior annular flow passage, the annular body including a fluid inlet and a plurality of circumferentially spaced apart fluid outlets in fluid communication with the interior flow passage, wherein each of the outlets has a swirl chamber formed within the annular body associated therewith for imparting swirl to fluid delivered thereto.
A multi-point injector comprising:
- a) a distributor ring defining a central axis and having a fluid inlet;
- b) an orifice ring connected to the distributor ring, the orifice ring defining a plurality of outlets circumferentially spaced apart with respect to the axis;
- c) an outer annular flow passage defined between the distributor ring and the orifice ring around the axis, the outer flow passage configured to provide for fluid communication between the fluid inlet and the outlets for supplying fluid to be sprayed from the outlets;
- and
- d) an inner annular flow passage defined between the distributor ring and the orifice ring around the axis inboard of the outer flow passage, the inner flow passage configured to provide fluid communication between the fluid inlet and the outlets for supplying fluid to be sprayed from the outlets.

An injector comprising:
- a) a nozzle body defining a central axis;
- b) a distributor ring within the nozzle body disposed around the axis thereof and having a fluid inlet;
- c) an orifice ring connected to the distributor ring, the orifice ring having a plurality of outlets circumferentially spaced apart with respect to the axis, wherein an interior annular flow passage is defined between the distributor ring and the orifice ring, the flow passage defining a portion of a first spray circuit and being configured to provide fluid communication between the fluid inlet and the outlets for supplying fluid to be sprayed from the outlets;
- and
- d) a heat shield operably connected to the nozzle body and configured to thermally isolate fluids in the flow passage.
