Definitions

  • the invention relates to a nozzle head for dispensing a flat spray jet of a coating agent, in particular an insulating material for the insulation of motor vehicle body components.
  • Such a nozzle head is known per se from the prior art and consists essentially of two identical outer plates and a thin, smaller center plate, which is inserted between the two outer plates, wherein FIG. 8 an embodiment of such a conventional center plate 1 shows.
  • the center plate 1 has spraying off an end edge 2 with a substantially V-shaped contour, so that between the adjacent outer plates and the front edge 2 of the center plate 1, a nozzle chamber is formed, in which the insulating material is introduced.
  • a flat, fan-shaped spray jet forms, which is well suited for the application of the insulating material.
  • the middle plate 2 has on both sides slots 3, 4 for the passage of screws in order to screw the outer plates to the middle plate 1.
  • the jet width - if the volume flow is kept constant - in the beam plane from a certain minimum distance in front of the nozzle head distance independent almost constant.
  • the beam width then varies only in a range of ⁇ 2 mm.
  • This distance-independent constant beam width is particularly advantageous in the treatment of strongly curved component surfaces, since it is then not necessary to maintain a constant distance between the nozzle head and the component surface when driving off the component surface.
  • the beam width varies depending on the volume flow of the applied insulating material, which is also acceptable within the scope of the invention.
  • a nozzle head for dispensing a spray jet of a coating agent wherein the spray jet is substantially flat in a jet plane and thereby has a certain beam width.
  • the nozzle head has two outer plates and an intermediate middle plate with outside tips on both sides and a central recess.
  • the general state of the art should also be pointed to the DE 10 2006 012373 B3 . JP 2000 237 679 A . US 2003/0155451 A1 . DE 10 2005 013 972 A1 and DE 10 2005 027 236 A1 ,
  • a disadvantage of the known nozzle head described above is the fact that the distance independence of the beam width is given only within a relatively narrow volume flow working range.
  • the beam width varies relatively strongly as a function of the distance to the nozzle head. An operation is therefore possible in practice only within the relatively narrow volume flow working range.
  • the invention is therefore based on the object to improve the above-described conventional nozzle head accordingly.
