Description

Se t. 18, 1962 w. F. STEINEN FLAT SPRAY ATOMIZING NOZZLE 2 SheetsSheet 1 Filed July 29, 1959 INVENTOR WILL IAM F. STEINEN ATITORNEY Sept. 18, 1962 w. F. STEINEN FLAT SPRAY ATOMIZING NOZZLE N E 2. "Q m; my Wm M mi v m Y Filed July 29, 1959 AT TOR/v57 United States The present invention relates to a flat spray atomizing nozzle and it particularly relates to a device for spraying aqueous or other liquids under high pressure for various purposes such as for the spraying of paints, irrigating liquids, fertilizers, metal treating liquid compositions and the like.
It is among the objects of the present invention to provide a high pressure atomizing nozzle which is especially advantageous in producing thin coatings of sprayed material which will produce a predetermined oval-shaped spray pattern which is particularly designed for spraying paints and other liquids, whereby it will be possible to use a relatively simple, readily produced and machined spray nozzle construction, which nozzle will be effective without the use of air or gas as an atomizing agent.
Another object is to provide a nozzle construction using hydraulic pressure for spraying without use of air or gas in which an elongated spray will be obtained without the necessity of utilizing complicated nozzle constructions and whereby by provision of a relatively simple nozzle head, an elongated spray pattern will be obtained.
Still further objects and advantages will appear in the more detailed description set forth below, it being understood, however, that this more detailed description is given by way of illustration and explanation only and not by way of limitation, since various changes therein may be made by those skilled in the art without departing from the scope and spirit of the present invention.
In accomplishing the above objects it has been found most satisfactory according to the preferred embodiment of the present invention to provide a main body for the nozzle having a centrally drilled passage through the spray tip thereof which opens upon an elongated peaked or ridged element at the central maximum elevation thereof.
Desirably the spray opening starts from a relatively wide internal chamber and is relatively narrow at its commencement and then slightly wider along a curvature extending along the top of the peaked ridge.
The spray angle is controlled by the radius of the enlargement which widens the bore and there is provided a disc or other insert which permits the water or other liquid to flow in a spiral or whirling motion toward the opening.
This insert has slots which are used to control the quantity of liquit which flows into the opening and there will. be a sufliciently wide and deep swirl chamber to assure that the liquid will pass through the opening in the nozzle at a relatively high circumferential velocity.
In the preferred form of the invention it is desired that the central peak have grooves along each side thereof with' relatively elongated flat parallel plateaus on each side of; the main groove.
In an alternative form of the invention there is a single peak with a central opening therein with the sides falling sharply down to the lower part of the nozzle device and without any parallel ridges or plateaus.
In either case there will be a fine elongated flat spray particularly useful for painting, irrigating, and many other atent industrial purposes, the pattern of which may be deliberately controlled according to the exact type of spray it is desired to achieve. This will be accomplished without the use of air or gas as an atomizing agent.
With the foregoing and other objects in view, the invention consists of the novel construction, combination and arrangement of parts as hereinafter more specifically described, and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which fall within the scope of the claims hereunto appended.
In the drawings wherein like reference characters denote corresponding parts throughout the several views:
FIGURE 1 is a side elevational view of one form of nozzle according to the present invention.
FIGURE 2 is a top plan view upon an enlarged scale as compared to FIG. 1, showing the central ridge or opening therein and the parallel adjacent Valleys and elongated plateaus.
FIGURE 3 is a transverse sectional view upon the line 3-3 of FIG. 2.
FIGURE 4 is a transverse sectional view upon the line 44 of FIGS. 2 and 3.
FIG. 5 is a transverse top plan view of the insert of FIG. 8 with the outer body omitted.
FIG. 6 is a side elevational view of an alternative construction showing a single elongated peak or ridge.
FIGURE 7 is a top view on the line 77 of FIG. 6.
FIGURE 8 is a side sectional view upon line 8-8 of FIG. 7.
FIGURE 9 is a fragmentary top sectional view at right angles to FIG. 8.
- Refer-ring to the first embodiment, namely FIGS. 14,'
which is screwed into a threaded portion of the nozzle',
body and has the flatted sides shown in face view in FIGS. 3 and 8 and side view in FIG. 4 and top view in FIG. 5'
to permit liquid to flow past the thread and into the cham-- ber between the insert B and the nozzle body A.
The main body A has a reduced diameter extension 10 with a'lower threaded mounting portion 11. Above this threaded portion is a step 12.
Above the step 12 is a hexagon portion 13 which terminates in the dome portion 14. The dome portion 14- has a top relatively fiat mount 15 of circular shape which is closed by' the ridge D, the grooves F and the plateaus G.
In the middle of the ridge and restricted to the high portion of the ridge is the opening E. This opening E is formed by drilling through at the peak 16 the cylindrical passageway 17. This entrance 16 is at the convergence or at the top of the conical wall 18 which terminates the cylindrical wall 19 of the chamber C.
More than half way up the length or height of the passageway 17 it is caused to flare outwardly as indicated at 24 in the direction of the length of the ridge D with a slighter flare being provided at 25' transverse to the ridge D.
This gives the oval form of opening 20 indicated in FIG. 2.
Internally of the chamber C there will be a disk 21 which may be threaded into position for the tangential or oblique slots 22 in the beveled face 23 thereof which fits closely across the oblique conical fact 18.
The threaded portion of the disk 21 is flatted as shown in FIGS. 3, 4, 5 and 8 to permit liquid to flow into the chamber between the insert and the body. It will be noted that the top of the insert has a central peak shown in side sectional view in FIG. 3 and top view in FIG. 5 and in side view in FIGS. 4 and 8 to guide the liquid from the grooves 22 into the conical chamber forming an entrance to the bore 16.
, An important feature of the present invention is the fact that the bore 16 opens on a flat face on the top of a ridge D or 51 and that it is flared outwardly so as to form a gore-shaped opening in this flat face from side to side but only a short distance as compared to the length of the ridge which extends the full width of the top of the dome 14 of FIGS. 1 to 4 and the corresponding dome of FIGS. 6 and 7 with the flat faces 50 extending obliquely upwardly to the ridge S1.
The top 35 of the disc 21 will leave a space 361eading to the inlet 16 of the passageway 17 which forms a swirl chamber 36. I
a This swirl chamber 36 will assure that the liquid flowing into the bore 17 will have a whirling movement.
As the whirling liquid leaves the widened portions 24 and 25 and the oval outlet in the peak or ridge D it forms an elongated flat spray which has a very definite outline the dimensions of which can be readily controlled by the curvature indicated at 24 and 25. The less curvature the more narrow the spray and the more curvature the wider the spray. The deeper the curvature extends into the bore 17 normally the wider the spray which will be produced.
This type of orifice with the peaked ridge and the side stabilizing grooves F and plateau formations G will give a most stable spray outline and oval-shaped spray pattern where accuracy is required a in spraying paints.
The radius of the curvature 24 and 25 will most accurately control the pattern. The swirling of the liquid will cause it to accurately follow the curvature 24-25.
In the alternative form of invention showing a ridge without the side valleys as indicated in FIGS. 5 and 6, there will be two large flats 50 on each side of the spray nozzle forming inclined sides with a single ridge 51 at the top therein.
This ridge will have a central opening 52 having an inlet at 53 from the conical chamber S4'and it will have a slight lateral curvature at 55' and a relatively wider curvature at 56 leading to the opening in the peak of the ridge.
These curvatures 5S and 56 will control the spray pattern and again will give a relatively wide elongated spray even though only a minute opening is provided in the center of the ridge 51.
The construction of the nozzle of FIGS. 5 and 6 is otherwise the same as the construction of th nozzle of FIGS. 1 to 4.
The applicant has thus provided a novel stabilized spray pattern which may be widely utilized in spraying paints and for other industrial purposes, which may be precisely determined in shape and form by the curvature of the outlet of the axial minute opening leading into the ridge which in the preferred form has parallel stabilizing valleys and parallel plateau portions on each side of said valleys.
While there has been herein described a preferred form of the invention, it should be understood that the same may be altered in details and in relative arrangement of parts within the scope of the appended claims.
