摘要： An injection nozzle for a spray device for drawing in a fluid suction medium by a fluid propellant which is under excess pressure and for spraying an admixture of the suction medium and the propellant. The injection nozzle has a nozzle housing, an injection chamber arranged in the nozzle housing, a jet nozzle which opens in the injection chamber for producing a propellant jet which is introduced into the injection chamber, and a fluid suction opening for the fluid suction medium. The fluid suction opening opens in an annular channel which has a flow connection to the injection chamber.
