An emitter for atomizing and discharging a liquid entrained in a gas stream is disclosed. The emitter has a nozzle with an outlet facing a deflector surface having a closed end cavity. The nozzle discharges a gas jet against the deflector surface. The emitter has a duct with an exit orifice adjacent to the nozzle outlet. Liquid is discharged from the orifice and is entrained in the gas jet where it is atomized.
