Definitions
- the present invention relates to a blowing nozzle for a blowing tool, which nozzle has at least two, preferably more outflow passages, each with a first end adapted to be supplied from the blowing tool with a pressurized gaseous fluid and with a second end comprising a blowing opening adapted to deliver said fluid in the form of a stream of fluid to an atmosphere surrounding the nozzle, at least two of the outflow passages being so orientated that streams of fluid delivered by the corresponding blowing openings can be directed towards an object which is to be treated with said fluid.
- Fluid streams refers both to continuous and to pulsating streams.
- Such nozzles can be applied to a large number of different types of blowing tool.
- An example of the use of such a blowing tool is the blowing clean of an object, for example a workpiece, with air or another gas, for example during turning and milling.
- Other examples are cooling, heating and drying and acting on the movement of various parts, for example in automatic machines.
- blowing nozzles and blowing tools have generated so much noise in operation that noise levels which are harmful to hearing or in any case are very disturbing, are reached.

- the bore holes 11 and 12 constitute a seat for a supporting body, not shown, for a valve, not shown, which is included in the blowing tool and which is adapted to regulate the streams of fluid through the blowing tool.

Abstract
Description
- The present invention relates to a blowing nozzle for a blowing tool, which nozzle has at least two, preferably more outflow passages, each with a first end adapted to be supplied from the blowing tool with a pressurized gaseous fluid and with a second end comprising a blowing opening adapted to deliver said fluid in the form of a stream of fluid to an atmosphere surrounding the nozzle, at least two of the outflow passages being so orientated that streams of fluid delivered by the corresponding blowing openings can be directed towards an object which is to be treated with said fluid. Fluid streams refers both to continuous and to pulsating streams.
- Such nozzles can be applied to a large number of different types of blowing tool. An example of the use of such a blowing tool is the blowing clean of an object, for example a workpiece, with air or another gas, for example during turning and milling. Other examples are cooling, heating and drying and acting on the movement of various parts, for example in automatic machines.
- Previously known blowing nozzles and blowing tools have generated so much noise in operation that noise levels which are harmful to hearing or in any case are very disturbing, are reached. Attempts have hitherto been made to reduce the noise level by various changes in the dimensions of the nozzle or of various parts of the blowing tool, or by forming the nozzle as a multi-hole nozzle, that is to say with a plurality of blowing openings.
- The object of the invention is to provide a multi-hole blowing nozzle, that is a nozzle with at least two, preferably more blowing openings, which has a considerably reduced noise level in comparison with known nozzles. This object is achieved by means of the invention in that the area of said blowing openings exceeds by at least 10 percent, preferably at least 15 percent, the minimum cross-sectional area of the passages just before the blowing openings.
- The invention is described in more detail with reference to the accompanying drawing which shows a preferred form of embodiment of a nozzle according to the invention. In the drawing, Figure 1 shows a longitudinal-section of the nozzle, where a small portion is also shown in side view, and Figure 2 shows a view from the front of the nozzle.
- In the drawing, 1 designates a nozzle in general with a nozzle body 2, preferably of metal, adapted to be secured by means of a suitable connection, to a blowing
tool 3 indicated by broken lines. The blowingtool 3 does not constitute a part of the present invention so that it is not described in detail here. - The nozzle body 2 comprises a
back portion 4, which becomes narrower in a taper forwards, and theexternal shell surface 4a of which, which is preferably axially symmetrical, forms the angle a with the central axis 5 of thenozzle 1. Theback portion 4 merges at 6 into anintermediate portion 7 which becomes narrower in a taper forwards and theexternal shell surface 7a of which, which is preferably axially symmetrical, forms the angle S with the central axis 5 of thenozzle body 1. - The angle a is preferably less than 15°. It can even be 0° in which case the
shell surface 4a is thus parallel with the central axis 5. - In the example shown, the angle β is about 20° but can have other values as described in more detail below. The angle can be greater than, equal to or smaller that the angle a.
- The
intermediate portion 7 merges at the front into a rounded nose portion 8. - A
cylindrical bore hole 9 is formed in the body 2 and merges at the front into abore hole 10 which becomes narrower in a taper. The wall of thebore hole 10 is preferably parallel to theshell surface 7a. - The
bore hole 10 merges at the front into a cylindrical bore hole 11 which ends with atapered bore hole 12. Thebore holes chamber 13 which is adapted to be supplied from the blowingtool 3 with a pressurized gaseous fluid, the pressure of which is more than 4 bars, preferably about 4 - 8 bars. Thebore holes 11 and 12 constitute a seat for a supporting body, not shown, for a valve, not shown, which is included in the blowing tool and which is adapted to regulate the streams of fluid through the blowing tool. In the forms of embodiment of the invention where such a supporting body does not occur, thebore holes 11 and 12 are absent. Otherwise, in the last-mentioned case, these bore holes would lead to an increased noise level. - A number of fluid passages in the form of
ducts 14, which have a circular cross-section with the diameter D, and with a cross-sectional area which is less than 3 mm2, connect thechamber 13 to the atmosphere surrounding the nozzle. Theducts 14 extend substantially parallel to the central axis 5 of the nozzle. - The entrance to the
ducts 14 consists ofinlets 15 in the wall of thebore hole 10, while the outlet of theducts 14 consists of blowingopenings 16 in theexternal shell surface 7a of theintermediate portion 7. As a result of the fact that theopenings ducts 14, the openings are ellipsoidal, the major axis of the ellipse being D/sins. As a result, theopenings openings 16 and the cross-sectional area of theducts 14 has a decisive effect on the noise level of the nozzle. A corresponding effect, although to a somewhat lesser extent, applies with regard to the area of theopenings 15 in relation to the cross-sectional area of theducts 14. - It has been found that a drastic reduction in the noise level is achieved if the angle s is reduced from 60° to just under 60°. Even with a reduction below 650, however, a certain reduction is noise is achieved. The value of 60° or 650 for the angle 0 gives an area of the
outlet openings 16 which exceeds the cross-sectional area of theducts 14 by 15 or 10 percent respectively. In the form of embodiment shown in the drawing, β is approximately 20°, as a result of which the area of eachoutlet 16 exceeds the cross-sectional area of theducts 14 by about 200 percent. - The same percentage increase in the area of the
outlets 16 in relation to the cross-sectional area of theducts 14 can be obtained if theducts 14 are inclined in relation to the central axis 5, so that they extend inwards or outwards in their fluid direction. If theducts 14 diverge outwards, for example, in relation to the central axis 5, by an angle γ°, an increase in area of 15 or 10 percent is obtained if the angle β between theshell surface 7a and the central axis amounts to 60-γ° or 65-γ°. - The angle γ should not exceed 20°, however, Preferably 8 should be less than 150, or better still less than 10°.
- In order that the said fluid, that is to say the streams of fluid which leave the blowing
openings 16, may be able to reach the object which is to be treated with the fluid to a sufficiently high extent, it is preferable that theducts 14 or in any case the part thereof situated closest to the respective blowing opening, should extend substantially parallel to one another or that they should converge on a point in front of the nozzle, where the object is. If the object which is to be treated with the fluid does not have too small an extent, theducts 14 may naturally be allowed to diverge outwards somewhat. In all the said embodiments, however, the aim should be that the streams of fluid reach the object in an assembled group. - Between the
openings 16 there are disposed wing-shapedradial flanges 17 which extend with increasing height from the back end of thebody portion 4 to just in front of theopenings 16 where the edge of the flanges is rounded at 18. If the angle a is nil, however, theflanges 17 nevertheless have a constant height along theshell surface 4a. In front of theopenings 16, the flanges have a height H, which should be greater than the diameter D of theducts 14, preferably greater than D/sinβ. Through the presence of theflanges 17, theopenings 16 are protected from damage which might otherwise occur as a result of the orientation and shaping of the blowingopenings 16 arranged according to the invention. Such damage can lead to an increased noise level. The presence of the flanges therefore ensures that the low noise level achieved according to the invention is retained. Another advantage of theflanges 17 is that they serve as a skin protection during the handling of the blowing tool. - The
flanges 17 may approriately be made of metallic material but they can also be of plastics, rubber or like material. - Although the drawing shows a nozzle with eight blowing
openings 16, it is obvious that fewer or more blowing openings may be provided. In addition to the ring ofopenings 16 shown, one or more central, conventional, blowing openings can be provided in the nose portion 8 of the nozzle. The presence of such a central blowing opening, which does not have any or at any rate any appreceiable increase in area, naturally has a certain effect of increasing the noise level. In certain cases, however, one or more such central holes can be warranted, particularly if it is desired to achieve a greater concentration of fluid round the central axis of the nozzle. - It is further obvious that the nose portion 8 can be flat instead of being rounded. In this case, the blowing
openings 16 can be disposed either in the flat nose of the nozzle or in the edge thereof, so that they open out partially in theshell surface 7a of the nozzle and partially in the periphery of the flat nose. Even with a nozzle with a flat nose, however, the blowingopenings 16 can be situated entirely in theshell surface 7a. - Nor is the invention limited to like
straight ducts 14. Instead, these can consist, for example, of a plurality of different duct portions, which form angles with one another, where the portion situated closest to the blowingopenings 16 preferably extends substantially parallel to the central axis 5 of the nozzle, or of helical fluid passages. The ducts can also have a varying cross-section along their length. In the last-mentioned case, it is the cross-sectional area of theducts 14 just before theoutlets 16, seen in the direction of the fluid, which should be related to the area of theoutlets 16. Similarly it is the cross-sectional area of theducts 14 just after theinlets 15, seen in the direction of the fluid, which should be related to the area of theinlets 15. - Although the
ducts 14 are shown with a circular cross-section, it is disclosed that they can have another shape, provided that their minimum cross-sectional dimension is less than 2 mm.
