Title: Spray nozzle with directly mounted plate

Abstract: A spray nozzle includes a central swirl chamber (9), receiving the fluidtangentially through lateral fluid inlet channels (14) from a peripheralfront cavity (8), and projecting the fluid in outlet through a coaxialoutlet passage (12). The coaxial outlet passage (12), the central swirlchamber (9) and the fluid inlet channels (14) are made up of ribs andrecesses in a front plate (15) engaged between a nozzle (1) hollow bodyand a rear core (5) which is itself formed by a core rear body (5a) and arear plate (5b) with rear axial recess (17). Thus one can economicallyproduce fluid inlet channels (14) and a central swirl chamber (9) withcoaxial outlet passage (12) and rear axial recess (17) with very accuratedimensions, thereby ensuring satisfactory reproducibility of the featuresof the fluid spray jet at the outlet.
