Definitions

  • the invention relates to a spray gun for atomizing liquid Media, in particular paints and varnishes, using compressed air, essentially consisting of a tubular, provided with a handle and connectable to a compressed air line, a housing in this atomizer nozzle supported opposite the handle and one interacting with this, adjustable by means of a trigger guard in the housing held nozzle needle, the housing with a Inlet opening for feeding the medium to be atomized from a Storage container or a feed line equipped and the adjustment path the trigger guard can be determined by an adjustable stop.
  • the object of the invention is therefore the spray gun of the aforementioned Genus in such a way that the setting of the nozzle needle and thus the opening cross section of the atomizer nozzle by limiting the Stroke of the trigger guard is to be carried out in a simple manner and in a short time. It should also be achieved that when the trigger guard is attached to the Stop the respective position of the nozzle needle is easily recognizable, so that settings easily matched to the medium to be processed repeat and that the setting can be made in a short time can.
  • the adjusting nut should have an axially projecting stop, to limit the rotational movement of the adjusting nut in the circumferential direction with the Plate interacts, and the outer surface of which should be the one Marking identifying the twisting path.
  • the plate can be assigned a compression spring, which in a the plate incorporated recess and inserted on one or both sides of the Housing and / or the handle should be supported.
  • a spray gun is designed according to the invention, it is not only short-term an adjustment of the medium through which the medium to be processed can flow Cross section of the atomizer nozzle by a position-oriented adjustment of the To make nozzle needle, but it is also the respective one without further ado End position of the adjusted nozzle needle can be seen.
  • About the twist of the Adjusting nut, which acts on the stop, through which in turn the stroke of the the nozzle needle is necessarily bound trigger guard is namely the respective opening cross section of the atomizer nozzle is determined. repeated Settings can thus be made easily.
  • the adjustment range of the nozzle needle is only one Rotation of the adjusting nut is assigned.
  • the respective settings are thus to accomplish quickly, are also to the proposed design too manage, only a few components required, a safe, trouble-free Operation over a long period of time with simple handling is accordingly guaranteed.
  • the spray gun shown in Figure 1 and designated 1 is used for Atomization of liquid media, e.g. Paints and varnishes, and consists of a housing 2, on which a handle 3 is attached, and one on the Housing 2 by means of a union nut 6 supported atomizer nozzle 4, with a nozzle needle 5 slidably inserted in a sleeve 10 cooperates.
  • a union nut 6 supported atomizer nozzle 4 with a nozzle needle 5 slidably inserted in a sleeve 10 cooperates.
  • an inlet opening 7 is incorporated, which by. one Connection piece 8 for holding a storage container 9 for the atomizing medium is surrounded.
  • the nozzle needle 5 can be actuated, so that in the Housing interior 13 pending air pressure - the compressed air is not over a drawn hose line, which can be connected to the housing 2, supplied -
  • the medium located in the reservoir 9 through the inlet opening 7 in the space 12 between the sleeve 10 held by means of a web 11 and the Nozzle needle 5 can emerge more or less open atomizer nozzle 4.
  • the adjustment path of the nozzle needle 5, which is conical in the area of the atomizing nozzle 4 is tapered, and thus the size of the outlet cross section is with Using a stop 21 with which the trigger guard 14 cooperates, adjustable.
  • the stop 21 is by a axially inserted into a recess 22 machined into the handle 3 adjustable plate 23 formed by the force of a spring 25 on a Adjusting nut 31, namely on the end face 33 thereof.
  • the spring 25 is here as can be seen in particular from FIG. 3, into a plate 23 incorporated recess 24 used and is supported at one end this and the other end on one provided on the handle 3 Stop 18 from.
  • the adjusting nut 31 is on the end opposite the atomizing nozzle 4 the housing 2 screwed on.
  • an external thread is in the housing 2 19 and in the adjusting nut 31 an internal thread 32, which is designed as a high-helix thread can be incorporated, also on the adjusting nut 31 is one of these aixal protruding stop 35 attached to the plate 23 in the circumferential direction interacts.
  • the adjusting nut 31 can thus only about one turn be twisted.
  • the end face 33 of the adjusting nut 31 is uniformly over the Provided circumferentially distributed locking recesses 34, and the plate 23 has a centrally arranged locking projection 26 which in the Locking recesses 34 can be inserted.
  • the adjusting nut 31 is against unwanted twists, e.g. caused by vibrations can, secured.
  • a mark 36 attached by means of the position of the stop 21 and thus the stroke of the trigger guard 14 and in turn the position of the Nozzle needle 4 can be determined.
  • the trigger guard 14, which has a molded-on cam 15 with the Plate 23 cooperates, can thus in spraying work to the plant Plate 23 can be adjusted.
  • the nozzle needle 5 via a bolt 16 on the Trigger guard 14 is articulated, this is against the force of a return spring 17 in the sleeve 10 until the cam 15 abuts the plate 23 as well adjusted accordingly, so that the flow-through cross-sectional area of the Atomizer nozzle 4 as a function of that determined by the stop 21 End position of the trigger guard 14 is to be set.
  • the on the adjusting nut 31 attached mark 36 allows known to a certain one cross-sectional openings assigned to the processing medium can be easily adjusted.
