Definitions

  • the invention relates to a spray gun for the atomized spraying of a flowable spray according to the preamble of claim 1.
  • a spray gun of this type DE-C-97344
  • a compressed air nozzle channel and a spray medium channel the other end of which dips into a paint container, coaxially in one Jet.
  • the upper space of the container is connected to the atmosphere via a special ventilation channel, the atmosphere opening being adjustable.
  • a control air duct leads from the nozzle duct into the ventilation duct.
  • the pressure in the upper chamber is therefore between the atmospheric pressure and the nozzle channel, it being possible for the setting of the atmosphere opening to bring it closer and closer to one or the other limit value.
  • the atmosphere opening When the atmosphere opening is closed, there is overpressure in the container, which sends the spray to the nozzle drives. If the atmosphere opening is completely opened, the upper pressure vessel space is so little above the atmospheric pressure that the pressure difference is not sufficient to lift the spray medium up to the nozzle. By adjusting the atmosphere opening, the liquid supply to the nozzle can thus be set between zero and a maximum. However, because of the inevitable drop in pressure in the atmosphere opening, the pressure in the container cannot quite reach atmospheric pressure or even drop below it. For this reason, the amount of spraying agent supplied to the nozzle can only be reduced to zero if the spraying agent container is arranged geodetically below the nozzle. This forces the user to hold the spray gun in a certain position, which is undesirable in some applications.
  • This enables the production of particularly fine spraying devices, for example for the graphics industry, which on the one hand are particularly easy to control and can be handled without regard to their position and on the other hand are particularly small and precise because the control of the spraying agent does not depend on a needle valve.
  • the mouth of the spray agent can be bought without risk of clogging Approx. 1/10 of the conventional opening diameter can be reduced so that even very small amounts of spray can be dosed and applied homogeneously.
  • the outlet opening is preferably designed as a storage gap, which can be covered, for example, by means of a fingertip resting on it.
  • the venting channel can be extended on the output side, for example, by a flexible, elastically deformable hose, with which in particular the color flow can be adjusted by mouth control.
  • an adjustable valve is provided in the ventilation duct, with which an exact comparison between the internal pressure of the supply container and the suction pressure is possible.
  • an adjustable outlet valve is provided parallel to the outlet opening, by means of which the overpressure which forms in the ventilation duct is limited to a maximum pressure.
  • the spray gun according to the invention can also be used as an ink pen.
  • the spray medium channel protrudes from the air nozzle in the manner of a paint tube, so that the paint liquid can be applied directly to a drawing pad by means of its tip and without atomizing pressure.
  • the spray gun according to the invention is also a sandblasting device device can be used.
  • the sand used as a spray agent is swirled in a storage container with the control air supplied to form a sand-air mixture which is discharged via the nozzle channel projecting into the storage container.
  • the spray gun has a continuously adjustable pressure reducing valve inserted between a conventional compressed air source and the compressed air inlet of the spray gun.
  • FIG. 1 The known basic structure of a pneumatically controlled spray gun is shown in FIG. 1.
  • This comprises a nozzle channel 16, which tapers towards its mouth towards a mouthpiece 14.
  • the spray medium channel 26 is arranged coaxially fixed in the nozzle channel 16, which ends at one end in a storage container 10 and ends at the other end in the mouthpiece 14.
  • the compressed air supplied to the nozzle channel 16 via a compressed air channel 20 connected to it flows around the spray medium channel 26 in the axial direction and emerges from the mouthpiece 14 exerting a suction effect on the spray medium channel 26 from the nozzle channel 16.
  • the emerging air stream entrains the emerging from the spray medium channel, whereby it is atomized and mixed with air, so that it e.g. can be applied to workpieces.
  • the internal pressure P1 of the container 10 can be adjusted by means of a ventilation channel 22 which connects the container 10 to the ambient atmosphere P2 near its outlet opening 28.
  • Compressed air flows into the ventilation duct 22 via a control air duct 24 connected at one end to the ventilation duct 22 and at the other end to the compressed air duct 20, as symbolically indicated by vector arrows, the air flow being directed in the direction of the outlet opening 28.
  • the amount of air flow can be continuously adjusted between a maximum negative pressure when the outlet opening 28 is fully open and a maximum excess pressure when the outlet opening 28 is closed.
  • the spray gun according to the invention shown in Figure 4 consists of a Device shaft 30 with a control head 32, a container part 34 arranged at the rear end thereof and a stylus part 36 which can be locked with the container part 34 by means of a bayonet lock 37.
