Definitions
- the subject of the present invention is a spray nozzle for regulating the flow rate per unit of time, consisting of a nozzle sleeve and a nozzle core which is mounted inside the nozzle sleeve.
- Such spray nozzles can include are used in mechanical spray systems, e.g. in atomizer pumps or spray cans which use compressed gases such as air or nitrogen or soluble gases such as CO2 or N2O as the driving force, the spray nozzle according to the invention, in addition to the very fine atomization of liquids, also keeping the emissions per unit of time at least approximately constant, and this , although the pressure drops when the aforementioned gases are used during the emptying of the can.
- a spray nozzle for regulating the flow rate per unit of time which is characterized in that feed channels open into first feed channels, which feed a first rotary channel lying in a direction of rotation, which feeds from this into Reverse direction of rotation to the previous direction of rotation, open out at least second feed channels and communicate with a hole.
- the second feed channels can be connected towards the inside with at least one second rotary channel which is connected at least by means of third feed channels to an inner ring channel which is connected to the bore, the counter-rotating channel being Set sides of a rotary channel arranged feed channels run in the opposite direction at an angle to the radial direction.
- An advantageous embodiment is characterized in that the first round channel is a hexagon, while the second round channel forms a pentagon, that the first round channel is fed with seven first feed channels and the second round channel with five second feed channels, and that, from the second Outflow concentric channel, three third feed channels designed as tangential channels open into the ring channel.
- This arrangement results in a particularly effective mode of operation and an original structure.
- At least the first rotary duct is provided with constrictions, to which, essentially perpendicular to them, air ducts are provided which are connected to the outside air via bores.
- a high level of atomization is achieved by drawing in the outside air under the VENTURI effect.
- FIG. 1 shows a front view of a spray nozzle according to the invention stored in a nozzle sleeve
- FIG. 2 shows a sectional view of the spray nozzle according to FIG. 1
- 3 shows a sectional view of a dispensing element containing an inventive spray nozzle
- FIG. 4 shows a front view of another embodiment of a spray nozzle according to the invention
- FIG. 5 shows a front view of a spray nozzle according to the invention which draws in outside air
- FIG. 6 shows a sectional view of the spray nozzle according to FIG. 5.
- the spray nozzle according to the invention is designed in such a way that it changes by means of brisk changes in the direction of flow of a pressurized liquid causes turbulence which, on the one hand, influences the amount of ejection per unit of time in such a way that it remains at least approximately constant and, on the other hand, atomizes it very finely by means of an extremely violent splitting of the liquid.
- the surface of the finely atomized liquid becomes larger than that which has coarser droplets, as is the case with the known spray nozzles. This larger droplet surface leads to faster evaporation, which is extremely important when using water as a solvent.
- nozzle sleeve 1 shows the inside of a nozzle sleeve which has feed channels 2, via which a liquid, not shown, reaches feed channels 3 which open into a large rotary channel 4.
- the inlet direction of the feed channels 3 is chosen here in the opposite clockwise direction.
- feed channels 5 run, this time clockwise, in the direction of a small rotary channel 6.
- annular channel 7 In the center of the nozzle sleeve 1 there is an annular channel 7, into which tangential channels 8 open, this time again in the counterclockwise direction.
- Around the bore 9 of the nozzle sleeve 1 there is a bead 10 which has the most favorable effect on the splitting of a liquid.
- the nozzle sleeve 1 is provided with a recess 11 which serves to distribute a liquid, not shown, to the feed channels 2.
- FIG. 3 shows an output element 12 with a core 13 which is mounted in the nozzle sleeve 1.
- the core 13 is provided with a cavity 14 which is located in the direction of escape with a bore 15 of the output element 12.
- the Cavity 14 serves to avoid deformation of the end face of the core 13 when the dispensing element 12 is produced by the injection molding process, because the end face of the core 13 must be as flat as possible around the feed channels 3 and 5, the concentric channels 4 and 6, to cover the tangential channels 8 and the annular channel 7 in such a way that they become lines and any spilling out of the channels is avoided.
- the dispensing element is provided with a main channel 16, from which bores 17 and 18 open into the recess 11 of the nozzle sleeve 1, from where a liquid, not shown, passes through the various channels of the nozzle sleeve 1 to its bore 9 and is expelled atomized there.
- FIG. 4 shows an extremely advantageous embodiment of the spray nozzle according to the invention. It shows the inside time of a nozzle sleeve 19 with a recess 20.
- the nozzle sleeve 19 has a large, seven-sided rotary channel 21, in the corners of which, here in the counterclockwise direction, feed channels 22 open which lie in the direction of alignment with the sides of the large rotary channel 21 ⁇ gen.
- the depth of the nozzle sleeve is selected such that it hermetically seals the cavity 14 of the nozzle core 13 and the bore 15 of the dispensing element 13, so that no leak can occur there.
- FIG. 5 shows an embodiment of the spray nozzle according to the invention, the nozzle sleeve 27 of which has a large rotary channel 28 which is provided with constrictions 29 into which, perpendicularly to them, open air channels 30 which connect to the outside air via bores 31 stand.
- These constrictions 29 implement a VENTURI effect, a liquid accelerating through the constrictions 29 sucking in outside air via the air channels 30 and their bores 31 and mixing them with the liquid, after which the sucked-in air compresses into the liquid in the subsequent smaller channels ⁇ is lubricated, so that it relaxes explosively when leaving the bore 9 in contact with the atmospheric pressure and thus the mechanically atomized liquid is broken up into even smaller droplets.
- the air ducts 30 can be lengthened axially as shown by the dashed lines 32 and then connecting them to ducts 33 which are perpendicular to them and which connect with the Connect outside air.
- the spray nozzle according to the invention is of course not limited to use in an output element 12. It can be used wherever a liquid is atomized, which is under a variable pressure, such as sprinklers, fire brigades, spray etc., in which case an independent nozzle core 13 is then pressed into a nozzle sleeve 1, which are then stored together in a tube part which can be connected to tube or hose lines.
- the spray nozzle has first feed channels, which feed a first rotary channel lying in one direction of rotation, and only second feed channels, which open out from this in the opposite direction of rotation to the preceding directions of rotation and are connected to the outlet bore.
- first feed channels which feed a first rotary channel lying in one direction of rotation
- second feed channels which open out from this in the opposite direction of rotation to the preceding directions of rotation and are connected to the outlet bore.
- the second feed channels which can be designed as tangential channels, can be connected to the bore via an annular channel or directly.
- the spray nozzle can also be advantageous to provide the spray nozzle with more than three nested feed channel families and more than two rotary channels.
