Definitions

  • the invention relates to a nozzle arrangement for a paint spray gun and a paint spray gun with such a nozzle arrangement.
  • a nozzle arrangement according to the preamble of claim 1 is known for example from DE-U-90 01 265.8.
  • the nozzle arrangement described therein has a central outlet opening for the paint, which can be closed with an axially extending needle.
  • the paint runs without pressure from a flow cup to this lockable outlet.
  • the outlet opening is surrounded by an annular gap, from which a high-speed ring air jet emerges, which in this case sucks, atomizes and entrains paint from the outlet opening, whereby a round jet of paint particles is formed.
  • the nozzle arrangement has two protruding horns laterally in the jet direction, the horn air jets of which are directed obliquely and in the same direction as the outflow direction and deform the circular jet.
  • the nozzle arrangement has on both sides of the outlet opening in the direction of the horns to two or more control bores, through which air exits, which strikes the horn air jets and thus controls them. Both the annular gap and these control bores are acted upon by air from the same air space, namely an annular channel within the nozzle arrangement.
  • This ring channel is supplied with compressed air from supply bores which are located in a paint nozzle and whose axes are arranged in parallel and equidistantly on a circle around the axis of the nozzle arrangement.
  • the arrangement described has the disadvantage that the air does not flow uniformly into the annular gap due to the circumferential supply bores within the nozzle arrangement, so that the air-color mixture is not optimally distributed in the round jet. If the air pressure were measured along the circumference of the annular gap, this would result in an approximately sinusoidal modulation, with maxima occurring in the angular ranges of the annular gap, in which the holes are located and minima in between. Furthermore, this arrangement has the disadvantage that the air from the supply holes, depending on the angular position of the paint nozzle having the holes relative to the housing or to the air cap of the paint spray gun, directly enters the control holes for the horn air when the supply holes are approximately colinear with these control holes.
  • the ring channel is also supplied with air via a series of axially parallel bores arranged on a circle.
  • the air is supplied to these holes through a supply hole that opens into another ring channel.
  • An air deflection disk is arranged in this further ring channel, which causes the air to be distributed homogeneously over the bores.
  • the paint spray gun shown in Figure 1 consists essentially of a housing 30 which has an upper part with a hanging hook and a handle 45 includes.
  • a compressed air supply line is connected to the underside of the handle 45, it being possible for an air throttle 40 to be installed at the air inlet, particularly in the case of low-pressure guns, to reduce the pressure; a flow cup for the paint is placed on a connection 46 on the upper side.
  • the actuating lever 31 simultaneously releases the compressed air via a valve arrangement 32 and the outlet opening 3 for the paint via a needle actuating device 33.
  • the paint flows from the (not shown) flow cup without pressure support to the outlet opening 3 and exits there with the needle 7 withdrawn.
  • compressed air flows through a line system to the annular gap 5, which surrounds the outlet opening 3, and generates a vacuum directly at the outlet opening 3.
  • This vacuum draws paint out of the outlet opening 3, which is atomized and entrained by the rapidly flowing air to form a round jet.
  • the omnidirectional jet is compressed by two horn air jets, which are compressed from the upstream horns 21, which form part of the nozzle arrangement 1, in such a way that an omnidirectional jet is formed into a flat jet.
  • the air flow from the outlet holes 20 of the horns 21 is in turn influenced by control bores 22, which are not provided with reference numbers in FIG. 1.
  • the axis 4 always being the central axis of the nozzle arrangement, in which the needle 7 is also located, and with the exit direction 12 the main jet direction of the exiting air represented by the arrow 12 - Color mixture is meant.
  • the nozzle arrangement 1 shown in FIG. 2 essentially consists of a paint nozzle 11, which is screwed into a nozzle insert 10 (compare FIG. 1) of the paint spray gun 2 via an external thread 34.
  • the paint nozzle 11 is surrounded by an air cap 16 which is screwed to an external thread of the nozzle insert 10 with the aid of a union nut (not shown).
  • the needle 7 is not shown in Figure 2.
  • a central part 35 of larger diameter adjoins the external thread 34 of the paint nozzle 11 for screwing into the nozzle insert 10, which is hollow on the inside for receiving the needle 7 and has an annular recess 47 on its rear side facing the external thread 34.
  • the paint nozzle 11 also has a front region 13, which extends from the exit of the bores 8 extends to the front end of the paint nozzle 11. This front area is divided into a cylindrical part 36, the diameter of which is small enough to keep the front end of the bores 8 clear.
  • This cylindrical area 36 is followed by a further, disk-shaped cylindrical area of larger diameter, which is relatively thin and is referred to below as an air deflection disk 9.
  • the diameter of the air deflection disk 9 is dimensioned such that it covers the bores 8 completely when viewed from the front.
  • the foremost region of the paint nozzle 11 is finally divided into a conical taper 23 at a first angle of approximately 30 ° to the axis 4, a subsequent conical taper 24 at a second, smaller angle and a cylindrical end region 25 adjoining it.
  • the air cap 16 surrounding the paint nozzle 11 in the assembled state is essentially symmetrical in its inner region to the axis 4, but has two horns 21 which are diametrically opposed to one another and project in the outflow direction 12 beyond the annular gap 5 and the outlet opening 3.
  • Two supply bores 19 run from the rear of the air cap 16 to outlet holes 20 in the horns 21, each horn 21 having two holes 20.
  • the holes 20 are oriented in such a way that they point to the axis 4 in the exit direction 12 after the annular gap 5, that is to say they can influence the air which has already escaped from the annular gap 5.
  • the air cap 16 finally has a central region which ends at the annular gap 5.
  • This central area is penetrated by four control bores 22, which are arranged on a line between the two horns 21, the air flow can in turn influence the horn air from the outlet holes 20 of the horns 21.
  • the inner wall of the air cap 16 (which will later be referred to as the outer wall 15 of the annular channel 6) curves continuously until it is parallel to the axis 4 in its course. So there is no sharp transition here.
  • the assembled arrangement of paint nozzle 11 and air cap 16, as shown in FIG. 2, forms an annular channel 6 between the outer surface of the front area 13 (with 36) of the paint nozzle 11 and the inner surface of the air cap 16. This begins at the end of the bores 8 and runs past the air deflection disk 9 up to the annular gap 5. It is only open to the outside through the control bores 22.
  • the outer wall 15 of the ring channel 6 initially tapers continuously in the course of the bores 8 to the ring gap 5 beyond the area of the air deflection disk 9. A discontinuous jump then takes place on a face ring surface 17 which is oriented essentially perpendicular to the axis 4.
  • the outer wall 15 tapers again continuously and in the area of the center, that is to say the annular gap 5, continuously changes into a course parallel to the axis 4 without a sharp bend taking place.
  • the nozzle arrangement according to the invention works as follows when used on a paint spray gun:
  • the needle 7 is simultaneously withdrawn counter to the outflow direction 12 and the nozzle insert 10 is supplied with two compressed air streams which can be regulated separately on the paint spray gun, acted upon.
  • the external compressed air flow passes through the two supply bores 19 in the horns 21 of the air cap 16 to the outlet holes 20, which are directed downwards or upwards to the extension of the axis 4 in the outflow direction 12.
  • the internal compressed air flow enters the six bores 8 within the paint nozzle 11 into the ring channel 6. This compressed air flow impinges on the air deflection plate 9, which completely covers the bores 8.
  • a strongly turbulent flow thus arises between the outlet of the bores 8 and the air deflection plate 9, which also has considerable tangential components and distributes the compressed air in the circumferential direction.
  • the compressed air then flows through the narrow area of the ring channel 6 past the air deflection disk 9 and strikes the face ring surface 17.
  • the sudden change in direction in turn creates a relatively strong turbulence and thus a further homogenization of the pressure conditions.
  • the compressed air passes through the increasingly tapering rest of the ring channel 6, which then no longer has any corners or edges acting as flow deflections, but is kept as smooth and continuous as possible in order to obtain a certain laminarization of the flow.
  • the air flow which is practically completely homogenized in this way emerges from the annular gap 5, sucks the paint out of the outlet opening 3 in a manner known per se, atomizes it and entrains it to form an omnidirectional jet.
  • the flow velocity is increased by the air duct 6 tapering in the direction of the annular gap 5, that is to say there is an optimal conversion of the pressure gradient from the air duct 6 to the ambient pressure into speed.
  • the round jet formed in this way is also influenced in a manner known per se by the horn air from the outlet holes 20.
  • the horn air is in turn influenced in a known manner by the control bores 22, but in a substantially more homogeneous, reliable and uniform manner than in the known nozzle arrangements.
  • This is because a direct alignment of the control bores 22 with the bores 8 is no longer possible because the air deflection plate is in between 9 is located.
  • it is therefore irrelevant in which relative position the paint nozzle 11 and the air cap 16 are located since a direct inflow of the control bores 22 through the air emerging from the bores 8 through the air deflection disk 9 is always reliably avoided. Because uniform spray jet geometries are created, such a spray gun or nozzle arrangement can also be manufactured more quickly and cheaply.
  • the nozzle arrangement described can be used with both high-pressure and low-pressure paint spray guns, but has particular advantages with modern low-pressure guns, since they react more sensitively to pressure fluctuations.
