Definitions

  • the invention relates to a paint spray gun with an oscillating armature drive, consisting of a closed housing, an electromagnetic oscillating armature motor, a color pump driven by the latter and a nozzle tube with a spray nozzle protruding from the housing (cf. DE-A 2 653 981).
  • FIG. 1 shows an overall view of a spray gun 10, which has a closed housing 12, to which a handle 14 with trigger 16 is attached and from which - in the spraying direction - a gun tube 18 projects forward.
  • a tube for connecting the gun 10 to a - not shown - paint or paint container is designated. 4
  • an oscillating armature motor generally designated 36, which consists of a stator 38 with a coil 40 and an armature 42 articulated on the housing 12. If the coil 40 is fed with an alternating current via an electrical connection line (not shown), then the armature 42 oscillates at the frequency of the alternating current, specifically towards the gate 38 and away from it.
  • FIGS. 5 to 8 A second embodiment of the invention is shown in FIGS. 5 to 8.
  • the spray gun is labeled 100. It has a closed housing 102, an oscillating armature drive 104, a piston pump 106 and a pistol tube 108. Air inlets 110 are provided at the rear end of the housing 102 and care is taken to ensure that an open passage 118 remains free between the rocker arm drive 104 and the gun barrel 108.
  • the gun tube 108 is screwed to a pump housing 115 and concentrically and at a distance surrounds a spray nozzle 116.
  • a paint pump 106 which, like in the first exemplary embodiment, is driven by the oscillating armature of the oscillating armature drive 104 via a piston rod.
  • In the lateral surface of the gun tube 108 there are air inlet openings 120 a short distance from the spray nozzle 116, the purpose of which will be explained later.
  • openings 120 then ensure that enough air flows into the vacuum region and that there are no so-called color flashbacks.
  • these openings 120 must not be so large that they impair the air flow through the interior of the housing 102.
  • the amount of air drawn in through openings 120 is about 30%, whereas the air taken in through openings 110 and used to cool the rocker armature 104 covers a percentage of about 70%.
  • Fig. 8 finally shows schematically a particularly expedient design of the stator 138 of the oscillating armature drive 104. It can be seen that between the stator and the coil 142, which on it is attached, there is an air passage gap 144. The air sucked through the interior of the housing can thus also flow through the gap 144, which significantly increases the cooling effect.
