Claim Text:
1. A multipoint injector comprising: a nozzle body defining a fluid inlet in fluid communication with a plurality of feed bores, wherein a plurality of swirl chambers is defined on a radially outward surface of the nozzle body in fluid communication with the fluid inlet through the feed bores; and a nozzle tip mounted to the nozzle body, wherein the nozzle tip defines a plurality of injection orifices, each injection orifice aligned in fluid communication with a respective one of the swirl chambers for issuing a swirling spray of fluid passing from the swirl chamber through the injection orifice, wherein each respective swirl chamber is in fluid communication with two opposed tangential feed slots each in fluid communication with a separate one of the feed bores, wherein the feed slots are configured to convey fluid from the feed bores into the swirl chambers to induce swirl on fluids within the swirl chambers, wherein the swirl chambers and feed slots form a circumferential channel all the way around the nozzle body, and wherein there is a circumferential pattern around the circumferential channel with one feed bore between each adjacent pair of swirl chambers, and with one swirl chamber between each adjacent pair of feed bores.
