  • Patent number: 12209524
    Abstract: A diesel exhaust fluid (DEF) nozzle includes a first conduit, an outlet of the first conduit defining an inlet of a first mixing chamber; and a second conduit disposed around the first conduit, an outer surface of the first conduit and an inner surface of the second conduit defining a second flow path therebetween. A flow area of the second flow path decreases from an inlet of the second flow path to a throat, and increases from the throat to an outlet of the second flow path. The inner surface of the second conduit defines a peripheral wall of the first mixing chamber, and a peripheral wall of a second mixing chamber, the first flow path and the second flow path being in fluid communication with the second mixing chamber via the first mixing chamber.
