摘要： Spray nozzle assembly (300) is configured to generate a swirled spray (312) with improved rotating velocity ω and smaller uniform droplet size. Cup-shaped nozzle member (300) has a body portion (318) with a cylindrical side wall (320) surrounding a central longitudinal spray axis (322), a circular closed end wall (324) and an exit aperture (310) coaxial with the spray axis (322) and defined through the end wall (324). A fluid dynamic circuit (330) is formed in an inner surface (326) of end wall (324) and includes three inwardly tapered power nozzles (302, 304, 306) terminating in an interaction region (308) which is exhausted via the exit aperture (310). The power nozzles have respective longitudinal axes (334, 362, 382) offset with respect to the spray axis (322) with corresponding non-tangential angles of attack (352, 374, 394) configured to efficiently cause a fluid vortex in interaction region (308).
