A pressurized stream of liquid flowing into a body is divided into a plurality of angularly spaced jets (33) which are rebounded in an upstream direction prior to being guided in a generally radially outward direction by a deflector surface. During flow along the deflector surface (38), the liquid is formed into a thin and very turbulent sheet which impinges against the edge portion of a plate (42) and is shattered into small droplets. An annular curtain of pressurized air cross shears the droplets and breaks the droplets into finely atomized particles which are discharged through a spray nozzle. A cap (60) is disposed internally of a spray nozzle and effects active atomization of pressurized liquid flowing through the nozzle by creating turbulence in the liquid during the flow. Different caps may be used to create various selected spray patterns.
