3 Claims.
This invention relates to improvements in atomizing sprinkler heads, and a principal object of the invention is to provide a novel and improved device of this character characterized by highly efficient operation and a degree of adjustability to meet the various requirements.
More specifically an object of the invention is to provide a sprinkler nozzle capable of discharging a solid conical body of finely divided atomized liquid wherein the atomization is substantially uniform throughout.
The invention resides further in certain novel structural details and arrangements hereinafter described and illustrated in the attached drawings wherein:
Fig. 1 is a longitudinal sectional view of a nozzle body made in accordance with the invention;
Fig. 2 is a reduced top plan view showing the pattern of the atomized liquid as projected from said nozzle;
Fig. 3 is a side view partly in section of a sprinkler head made in accordance with the in vention;
Fig. 4 is a longitudinal sectional view of the sprinkler head;
Fig. 5 is an outer end view of the sprinkler head, and
Fig. 6 is a section on the line 6B, Fig. 3.
With reference more particularly to Figs. 3 to 6 of the drawings, a sprinkler head made in accordance with the invention may comprise a hollow generally cylindrical body member I threaded at one end as indicated at 2 for attachment in a sprinkler system and having an hexagonal portion 3 for reception of a wrench. Extending longitudinally or axially of the body from the threaded end thereof is a cylindrical bore 4 which terminates at its inner end in a plurality (s in the present instance) of ports 5, said ports diverging outwardly with respect to each other and with respect to the axis of the bore 4, which is also the axis of the nozzle.
The body member I has a reduced generally cylindrical axially disposed end portion 6 and the ports 5 are formed in the inclined wall 1 which joins this terminal end portion to the side wall of the bore 4. That portion 8 of the end portion or extension 6 of the body member which immediately adjoins the wall 5 is cylindrical in form and this cylindrical portion 8 terminates in a portion 9 of increased diameter. From the outer end of the portion 9 extends a substantially cylindrical or slightly tapered portion ll-ll which terminates in a radially enlarged head portion 12. The portion 9 is of somewhat greater diameter than the head portion I2 and these two portions form confronting relatively spaced substantially radial annular shoulders 13 and M. lhe shoulder I3 is provided with an annular series of projecting fins l5 which are angularly disposed with respect to radial lines emanating from the axis of the nozzle and these projecting fins l5 constitute deflector means having a function hereinafter described. The head portion l2 has in its outer end an axial reentrant recess i5, and a series of ports Ii distributed around the head portion extend convergently from the shoulder M to the wall of the said recess.
That portion of the body member which immediately adjoins the wall I is threaded, as indicated at I8, for reception of a sleeve member i9. This sleeve, of cup-like form as illustrated, forms a chamber which surrounds the extension 5 of the body member and with the inner end of which the ports 5 communicate. At its outer end the sleeve i9 is provided with a circular opening 2! having a cylindrical inner portion 22 and an outwardly flaring outer portion 23, and in assembly this port embraces the inner part of the head l2 as illustrated so that between the wall of the opening 2i and the surface of the head !2 an annular port is formed which is co-axial with the extension 5. Obviously the position of the opening 2! with respect to the head l2 and to the shoulders l3 and I4 may be varied by adjusting the sleeve in the axial direction through the medium of the associated threads.
In operation, water under pressure is admitted to the bore 4 from the sprinkler system and is discharged through the ports 5 into the annular discharge chamber 24 formed between the extension 6, which forms the inner wall of the chamber, and the wall of the sleeve 19.. This water is directed by the diverging ports 5 against the wall of the sleeve. At the outer end of the chamber the water passes through the transverse or radial channel 25 formed between the shoulder l3 and the confronting portion of the end wall 26 of the sleeve, and in passing through this channel the water contacts the inclined ribs 15 on the shoulder l3 and is deflected by these ribs so as to pass to the annular discharge in a substantially tangential direction as indicated by the arrows in Fig. 6. By reason of the restriction of the opening 2i and of the relatively small dimensions of the annular discharge port, a p r of the liquid is caused to pass through the auxiliary discharge ports ii. That portion of t e water which passes through the discharge port proper is broken up by the action of the deflector elements 15 and the narrow confines of the discharge port and is projected outwardly as a fine spray in a conical pattern as illustrated in Figs. 1 and 2. The water which passes through the ports ll converges in separate jets which intersect as illustrated in Fig. 1 to be broken up and atomized and to fill the central portion of the conical pattern so as to produce a substantially homogeneous cone of atomized liquid. As previously set forth, the sleeve is may be adjusted to modify the character and pattern of the discharge as may be required.
I claim:
1. In an atomizing sprinkler head, a nozzle body having a generally cylindrical solid extension, a sleeve attached at one end to said body and embracing said extension so as to form with the latter an annular chamber, the other end of said sleeve having an opening for reception of the outer end of said extension and forming with the latter an annular discharge port for said chamber, th wall of said body at the base of said extension bein apertured to provide admission ports to said chamber, an annular shoulder on said extension confronting the discharge port and forming in said chamber a transverse annular channel adjoining the inner end of said port, an enlargement at the said outer end of the extension forming an annular shoulder confronting the shoulder first named, and a plurality of supplementary discharge ports extending convergently from the second named shoulder to the outer surface of said extension.
2. A sprinkler head in accordance with claim 1 wherein the said sleeve is adjustable axially on the nozzle body to adjust the position of the said discharge opening with respect to the said extension.
3. A sprinkler head in accordance with claim 1 wherein the said admission ports are disposed so as to direct admitted liquid against the Wall of the sleeve.
