Abstract:
In a liquid spray apparatus comprising a liquid pressurizing means having a suction port for inhaling the liquid and a discharge port for discharging the liquid and for pressurizing the liquid, a liquid passage forming member communicated to said discharge port of said liquid pressurizing means, and a nozzle unit communicated to a discharge side of said liquid passage forming member and having a liquid spray port, the liquid sprayed from said liquid spray port of said nozzle unit is formed with a thin film shape liquid, the liquid spray apparatus is characterized in thatsaid liquid pressurizing means generates a liquid pressure fluctuation to the liquid and gives a pulsation movement on a surface of said thin film shape liquid and further gives a swirl component to said thin film shape liquid; and said thin film shape liquid sprayed from said liquid spray port of said nozzle unit is maintained in a thin film figuration to a desirable run down point without a film cut off, said nozzle unit mitigating pressure of the liquid which is pressurized abruptly upon starting the liquid pressurizing means, whereby during start of flow of liquid upon starting the liquid pressurizing means, liquid droplets from said liquid spray port of said nozzle unit do not scatter.
