  • the measuring device is 36 a pressure drop measuring device which, depending on a pressure drop of the flowing through the measuring channel 30 Outside air generates the measurement signal on the signal line 38.
  • to Measurement of the pressure drop only needs at one measuring point downstream of the flow restrictor 34 the air pressure in Measuring channel 30 to be measured, since this with the pressure of the Outside air in relation to an outside atmosphere inlet 32 in relation can be set. If the measuring channel 30 a capillary has a narrow cross-section, no additional Flow restrictor 34 required.
  • Flow cross section by a drive with it connected actuator 45 from the electronic Control device 21 is controlled depending on one Setpoint for the volume delivered per unit of time Additional air, which in turn depends on the setpoint for the powder rate and / or from the setpoint for the Conveyor air rate.
  • Additional compressed air is passed into the vacuum region 10, 26 are used to influence the negative pressure.
  • the vacuum prevailing in the vacuum chamber 10 or Vacuum is not absolutely constant and fluctuates itself then when the delivery air rate of the injector nozzle 6 and the Auxiliary air rate in the auxiliary air inlet 46 as well Powder level 48 kept constant in the powder container 14 become.
  • Such uncontrolled fluctuations in negative pressure in the vacuum chamber 10 also undesirably lead to fluctuations in the amount of powder conveyed per unit of time in the powder-air channel 2.

  • the Compensating air is supplied by the second atomizer nozzle Compressed air source 12 via a third variable flow restrictor 62 in a compressed air line 64 and via a Compensation air channel 66 supplied.
  • the powder suction channel 8 and the compensation air channel 66 are axially parallel in the Dip tube 24, in the lower end portion of which the second Injector nozzle 56 is arranged.
  • the powder inlet for the Powder suction channel 8 is through one or more Powder inlet openings 68 formed, which across the Dip tube 24 through the dip tube outer surface 70 and thus the powder 16 located in the powder container 14 with the second vacuum chamber 60 of the second injector 72 connect in terms of flow.

This will make the Controller setting times of the control device 21 which is trying to compensate for the fluctuations mentioned, much shorter. In trials, the standard setting times could be reduced to a third be shortened.
