4 Claims. (Cl. 299114) This invention relates to spray-type nozzles and is directed particularly to spray-type nozzles for producing a finely atomized liquid spray or fog.
An object of this invention is to provide a spray nozzle that has a high degree of atomization of the liquid discharged from the nozzle.
Another object of the invention is to provide a spray nozzle that does not clog.
Another object of the invention is to provide a spray nozzle with a high degree of atomization that is formed as a single piece and is resistant to deformation.
Another object of the invention is to provide a spray nozzle that provides a uniform spray of atomized droplets.
Another object is to provide a spray nozzle that is compact and inexpensive to manufacture.
Another object of the invention is to provide a spray nozzle that is rugged in construction and capable of being made from plastic materials.
Another object of the invention is to provide a spray nozzle that produces a narrow, angle, cone-shaped spray of highly atomized droplets.
Other and further objects of the invention will be apparent from the following description taken in connection with the drawings in which:
Fig. 1 is a side view of the nozzle;
Fig. 2 is another side view of the spiral vane of the nozzle at ninety degrees to the side view of Fig. 1;

Fig. 6 is a sectional view taken along lines 66 of Fig. 2;
Fig. 7 is a side view of another embodiment of the invention; and
Fig. 8 is an axial interior end view of the nozzle shown in Fig. 7.
In Figs. l4 a nozzle 10 comprises a tubular portion 11 forming a passage 12 and a helical-shaped vane 13 extending axially from the tubular portion 11. The vane 12 forms a helical slot 14 and has an inner wall 15 defining a bore 16 for delivering water from the passage 13 throughout the vane for discharge through the slot 14. The vane spirals inwardly and the wall 15 has an inward axial taper to form the bore 16 in a conical or bullet shape so that the cross section of the bore is reduced in the direction of flow through the nozzle.
The vane 13 has a helical surface 18 extending at an angle to the axis of the nozzle radially outwardly from the bore 16. The surface 18 extends from the tubular portion if to the surface 19 forming an edge 20 therewith. The surface 19 has a helical shape and extends outwardly at a greater angle to the axis than the surface 18. The surface 19 extends from the surface 18 to the end surface 21 at the tip of the nozzle. The nozzle has 2,804,341 Patented Aug. 27, 1957 "ice a cylindrical exterior surface 24 and a helical surface 25 forming the exterior surface around the outside of the vane 13 and tapered axially inward to form the nozzle in an outer cone shape. The surface 25 terminates at the surface 19 to form an edge 21. The tip of the nozzle has a surface 26 in the same conical plane as the surface 25 and forms with the surface 19 an exterior edge 27.
On the under side of the vane 13 there is a helical surface 28 forming an upper wall of the slot 14. The slot 14 between the surfaces 18 and 28 remains substantially uniform in cross section up to the line 20. The cross section of this passage is illustrated in Fig. 5. The surface 19 is at a greater angle to the radial plane, as illustrated in Fig. 6, to provide a full cone spray.
The surface 18 forms with the wall 15 an inner helical edge 31. The pitch of the edge 31 remains substantially uniform throughout the nozzle and spirals inward with the taper of the wall 15. The wall 15 forms an edge 32 with the surface 28. With the increase in pitch of the surface 19, the pitch of the edge 32 correspondingly increases so that the width of the wall 15 is axially reduced as its extends axially towards the end of the nozzle.
In viewing the nozzle axially through the passage 12, the inner wall 15 spirals inwardly with the wall at an angle so that the wall 15 has a component facing the stream of water entering the nozzle. The surface 18 spirals inwardly so that in extending axially towards the end of the nozzle, an increasing area of the surface 18 projects radially inward from the axially preceding wall portion. The surface 19 similarly projects inwardly from the axially preceding wall portion. The inner edge 31 terminates at an end portion 33 to form a plug at the end of the nozzle so that the water at the end of the nozzle is discharged over the surface 21. The liquid entering the nozzle first engages the upper portion of the edge 31 which extends radially inwardly of the cylindrical wall because of the curved taper of the wall 15. The curved tapering of the wall 15 and the tapering of the spiral of the surfaces 18, 19 present a continuous deflecting surface in the path of the water to peel off a sheet of water. The reduction in the cross sectional area of the bore by the curved taper of the wall 15 maintains the water as a homogeneous mass and reduces the turbulence or disintegration of the mass into separate portions. Thus throughout the length of the nozzle a uniform sheet of water may be peeled off by the vane 13 and atomized to form droplets.
The terminating spiral surface 19 is a complete turn between the edge 20 and the surface 21 so that the water, reaching the end of the nozzle, forms a complete finite conical sheet to eliminate any breaks in the spray. The reduction of the conical shape of the wall 25 reduces the width of the surfaces 18, 19 and thereby reduces the metal to liquid contact and the frictional losses of the admission of the water from the nozzle. This reduction in the outside diameter increases the atomization of the water and increases the efficiency of the nozzle.
In Figs. 7 and 8 another embodiment of the invention is shown in which the vane 41 has a tighter spiral. The surfaces 42, 43 are formed so that the edge 44 is inward of the inner edge 45 formed by the wall 46 of the bore and the helical surface 47. With this arrangement the spray has a more forward component so that it is shaped in the form of a cone having the major portion of the spray Within thirty degrees of the central axis of the nozzle. The edges 44, 45 are formed so that radially there is no overlapping. The wall 46 has a curved taper reducing the turbulence within the nozzle and providing a uniform sheet of liquid to be peeled off by the surface 42.
The above described nozzles have the particular advantageous features of providing a clear and open passage for the liquid to flow through. There are no obstructive elements in the bore or passages of the nozzles to become clogged with sediment carried by the liquid. The spiraling of the deflecting surface inwardly into the path of the water in the bore produces a continuous sheet of Water around the nozzle which disintegrates into a spray of uniform size droplets. The curved taper of the bore additionally contributes to the uniform distribution of the spray around the nozzle. The surfaces 18, 19 and 42 of the vanes in the various embodiments are preferably straight to permit the free and unobstructed discharge of the liquid through the helical slot. The width of the vane is reduced by tapering the exterior surface of the nozzle. In addition to the improved performance, the nozzle has the additional mechanical features of ruggedness and compactness. The vane does not need to be made of a great number of spirals to produce a desired uniformly distributed spray. One or two turns are all that i necessary, depending on the particular configuration that is desired. Also the open inner passages and the width of the helical slot provide for an easy and inexpensive machining of the nozzle. The end of the vane has a member for supporting the nozzle during the machine operation.
Various other modifications and changes will be made in the foregoing embodiments without departing from the invention as set forth in the appended claims.
