Definitions

  • This invention relates to an air brushing apparatus for spraying ink, paint or any other liquid for drawing a picture by use of high pressure gas to thereby perform brushing, and more particularly to a portable air brushing apparatus.
  • the conventional air brushing apparatus using compressed air is of such an arrangement that air compressed by an air compressor is fed into a main body of brushing apparatus through an air hose and blown out of the forward end of a nozzle to spray ink or paint in a container.
  • high pressure gas filled in a gas bomb is fed into the main body of brushing apparatus through an air hose and blown out of the forward end of the nozzle to spray ink or paint in the container.
  • the air compressor and the gas bomb are provided separately of the nozzle portion for spraying compressed air or high pressure gas and the aforesaid compressed air or the like is delivered into the main body of air brushing apparatus to be blown out, whereby the apparatus is large-sized and it is difficult to use the apparatus in portable condition.
  • the through-hole is formed in the seal plate of the high pressure gas bomb by the plug opening mechanism, to thereby open the plug.
  • the high pressure gas flows out into the gas flow-out control section through the through-hole formed in this seal plate.
  • the high pressure gas which has flowed out into the gas flow-out control section, is delivered into the gas pressure regulating mechanism and flows out into the nozzle section, while being regulated in gas pressure thereof.
  • the high pressure gas is discharged from the forward end of the nozzle section.

  • the displacement of the pressure regulating piston 215, i.e. the displacement of the gas pressure regulating pin 214 is stopped at a position where the biasing force by fluidal pressure acting on the fluid chamber A and the biasing force of the pressure regulating spring 221 are balanced, whereby gas leaving from the gas bomb 211, passing through the gas flow-out control section 201 and the fluid chamber A and flowing into the gas flow path 226 is regulated to a predetermined level of pressure.

  • the displacement of the cam 228 crossing the direction of the displacement of the pin 227a of the valve mechanism 227 is imparted to the pin 227a through the spherical body 229, whereby, for example, the biasing force acting on the pin 227a by gas pressure is not imparted to the rocking switch 233 through the spherical body 229 and the cam 228, so that the burden on the worker operating the rocking switch can be reduced.
  • the provision of the malfunction preventive cover 234 for closably shielding the rocking switch 233 makes it possible to prevent a malfunction caused by an accidental contact of the rocking switch 233 with a neighboring object during storing the air brushing apparatus, for example.
  • pressure of gas leaving from the gas bomb 211, passing through the gas flow-out path on-off operation section 203 and being fed to the nozzle section 204 is regulated to the desired value by the pressure regulating screw 223 threadably coupled to the outer periphery of the gas flow-out control section 201 from the outside in the gas pressure regulating mechanism 216, so that the particle diameter and the flow rate of the sprayed ink or the like can be varied in a wide variety by combining the above-described regulation with the regulation of the flow rate of gas blown out of the nozzle 236 by the nozzle opening value control valve 237 of the nozzle section 204, thus obtaining brushing results in a wide variety.
  • Fig. 12 is a sectional view showing the essential portions of a still further embodiment of the air brushing apparatus according to the present invention.
