! The feeding of the Parbo to the nozzle pipe 12 takes place through a sehematiBch channel registered at 213, which is connected to a sub Pressure-setting reservoir or a pump is connected "

The Spritspistöle is equipped in the usual way with einor actuating device 214, through which the supply or the blocking of the compressed air 206 is controlled and finally the feeding of Parbe and the feeding of the ffiedfer tension gur ionization device 2071 209. These actuating devices however, can also depend on the air flow be formed in the line 206.

In the embodiment shown and described, the nozzle 204 between the charge delivery device 207, 209 and the collecting device 211 has a lung of 5 to θ cm, while the diameter in the cylindrical part 204 c has a unit of 6 mia.

Experience has shown that when a compressed air source is used at a pressure of 4 bar, a supersonic flow is obtained at a speed of 450 m / 8okonds, which resulted from an excitation track voltage öx of the ionizing device 207, 209 of 5 kV and a resistance of 20 Megaohm in series with the fradol an oleic; * voltage of 40 kV · at the nozzle 212 uv4 a current output of 30 microamps.
