A multipoint injector includes a nozzle body defining a fluid inlet in fluid communication with a plurality of feed bores. A plurality of swirl chambers is defined radially outward from the fluid inlet of the nozzle body in fluid communication with the fluid inlet through the feed bores. A plurality of injection orifices are respectively aligned in fluid communication with the swirl chambers for issuing a swirling spray of fluid passing from each swirl chamber through each injection orifice.
