  • Two pins 23 are placed at the apex of the central body, each having an orifice exit 25 towards the axis of the central body and substantially perpendicular to it.
  • These holes 25 are in communication with two channels 24, which cross the wall of the central body in the direction of its axis and which are substantially perpendicular to the outlet ports 25.
  • These channels 24 are intended to send an air flow towards the top of the spray insert 37 at the base of the jet.
  • Their outlet orifices 25 can be replaced by slots.
  • channels 28 pass through the walls of the central body 2 in the direction of its axis to access to the respective outlet ports 29 ( Figures 6 and 7) placed at the top of the central body and which form an angle high-pitched with the spindle sticking out of the nozzle slot.
  • These four orifices 29 are intended to send an air flow which allows you to change the spray angle.
  • AT the interior of each of these channels 28 and at their base, is provided a thread 28a, which allows the introduction with a hexagon wrench screws 28b, which are used as air throttles. They are in the form of screws hollow with different bore diameters for the purpose to vary the air flow. All 28b screws in the same set have the same bore diameter. It is obvious that the channels 24 can also be provided with hollow screws 28b used to adjust the air flow.
  • the central body 2 has a groove in the form of a circular crown 27 collaborating for connection with the pistol and allowing passage low pressure air to the channels 24,28.
  • the pistols used in connection with the nozzle spray just described have a adjustment of compressed air which will be brought into the groove annular 27.
  • the adjustment of the compressed air flows of the holes 25, respectively 28 will be determined by choice holes of the hollow screws 28b.

  • the 32.32a shoulders can slide throughout grooves 22 towards the top of the central body 2 until said shoulders 32 strike the upper part of the notches 22.
  • the rotary element 3 is then located at the top of the central body 2 and the spray nozzle 37 is located above said summit. Seal 4 slides inside of the bore 30 of the central body 2 to ensure the seal between it and the gun not shown in the drawing.
  • the groove 41 of the cylindrical joint 4 ensures greater sealing since the central part 31 of the rotary element 3, in the form of a ball in the drawing rests on the two edges of the groove 41.
  • the cylindrical seal 4 has at its base the end seal 5 in polyamide plastic (nylon) which will connect head 1 to the gun and the seal “O-Ring” 6 in Viton which collaborates with the central body 2 inside its bore 30.
  • the spray head 1 When the spray head 1 is in its position work as shown in figure 1, the high fluid pressure arrives through bores 7a, 7 and continues its path through screw 39 and nozzle 37 connected by the O-ring 38 in Teflon.
  • the fluid that will come out under spindle shape through there spray nozzle 37 can be regulated with the addition of low pressure air by the means of the two series of channels (24,28) which go in the direction of the axis of the central body and inside its walls.
  • the pressurized air flows through the two channels 24 in coming from the groove 27 at the base of the central body 2 and reaches the outlet orifices 25, which form an angle substantially straight with channels, air at base pressure being projected substantially perpendicularly against the high pressure fluid spindle coming out of the slot the nozzle 37 reinforcing by this air supply the atomization of said fluid spindle.
  • low pressure air arrives at channels 28 which also start from the base of the body central 2 and traverses the interior of the walls of said body central 2 to reach the orifices 29 which have a tilt relative to channels 28.
  • Air based pressure passes through channels 28 and exits on one side and the other of the nozzle 37 at an acute angle with the central duct of nozzle 37, so that it is possible to adjust the opening angle of the fluid spindle that exits through the nozzle 37.
  • the rotary element can rotate 180 ° and the nozzle 37 is then placed so that its slot faces the exit from bore 7, ready for cleaning. This operation is very simple since the pin 34 will abut against the edges 26 of the recess 34a in the two opposite positions placing with precision the rotary element 3 in each case.
  • the variant of the head shown in Figures 8 to 11 includes a central body 2 through which a rotary element passes or identical key not shown in element 3 of the mode of Figures 1 to 7 and also provided with a seal not shown identical to the joint 4 of Figures 1 to 7.
