SPRAY NOZZLE WITH A PLURALITY 0F CONTINUOUS GROOVES Filed Jan. 18, 1961 2 Sheets-Sheet 2 3 2 Y INVENTOR. JOHN M 867'6 ,4 FFO/PIYEX Massachusetts Filed Jan. 18, 1961, Ser. No. 83,411 (Zlaims. (Cl. 239-548) This invention relates to the atomization or spraying of liquids and particularly to a simple, inexpensive nozzle system combining a number of small orifices working the liquid flow into a spreading foglike discharge of microdrops uniform in size.
Each orifice produces a spray which fans outwardly from the axis of the nozzle to produce a generally conical distribution of the whole expanding and falling as an even and gently wetting deposit.
FIG. 1 is a side view of the nozzle and spray formation;
FIG. 2 is a face view on enlarged scale of the nozzle with the orifices in a ring;
FIG. 3 is a sectional view further enlarged taken in the plane of line 33 of FIG. 2;
FIGS. 4 and 5 are still further enlarged views taken on lines 4-4 and '55 of FIG. 2;
FIG. 6 is a perspective fragment partially in section showing one aspect of the intersection of grooves A and B;
FIG. 7 is a section taken on the line 77 of FIG. 5; and
FIG. 8 is a section taken on line 88 of FIG. 7.
In the example shown in the drawings a garden hose has attached at 2 the nozzle 3 with its front piece 4 shaped and formed at front with the atomization and distribution system of this invention.
To attain this the front piece 4 with generally parallel front and rear surfaces 5 and 6 is specically formed with grooves A pressed in the front surface 5 and the circular, intersecting, orifice-forming groove B milled into the rear surface 6.
The front pressed grooves A are circular and of relat-ively smaller diameter and generally rectangular in section, and the three grooves are in symmetrical three cornered position around the center C of the nozzle, which is also the center of the rear groove B.
Bach'groove A is very small in section, about one hundredth of an inch radially, and forms a corresponding axially thin orifice ring 7 at the bottom. These orifice rings 7 of grooves A are intersected by the inner or rear groove B and cut away by the milling of the B grooving as shown to complete at one time all the orifices O.
The groove B is shaped in section to determine the surfacing of the orifice and particularly the inner or supply portion 8 theroef, :and in the preferred type shown in the drawings the groove is generally rectangular on the outer side 9 and inclined on the other at lit to become narrower in the direction of the flow and correspondingly influence Patented Sept. '17, 1963 the lines of flow to direct the discharge outward and avoid an excessive intermixing of the orifice discharges at the center; and the effect is also to contribute to give the even fan-type form without objectionable horns or jets at the outside surfaces.
The circular interrelation of the grooves A and B is simple, and also highly variable in determining the character of the spray formation. The angle of the cone will be widened by increase of diameter of groove B and cone spondingly a narrow angle hard driving fog may be obtained by decrease in groove B diameter.
in the present example the overall size is one inch diameter. The orifice size is important and very minute indeed to give maximum dissemination of the liquid. This in combination with the precision attained in control of the flow gives a most desirable type of spray in which there are a number of contributing formations each separately predetermined with precision and correspondingly per fecting the fin al spray.
This high accuracy is also attained in a simple and direct manner correspondingly dependable and inexpensive in requiring only two operations, a stamping and a milling, to ensure the perfect product.
I claim:
1. A spray nozzle adapted to receive liquid flow under pressure comprising a platelike piece having front and rear surfaces, said rear surface having a continuous circular groove retaining liquid to single flow under pressure, and said front surface having a plurality of continuous grooves intersecting said continuous groove at a number of points and providing pairs of generally axially directed orifices at the intersections, the number of orifices exceeding the number of grooves and the diameters of said grooves being less than that of the first mentioned groove.
2. A spray nozzle as set forth in claim 1 in which the rear surface groove is narrow in cross section in the direction of flow at the intersections.
3. A spray nozzle as set forth in claim 1 in which the rear surface groove has its inner surface formed to narrow the outflow and correspondingly deliver the discharge outward.
4. A spray nozzle as set forth in claim 1 in which the front surface grooves are symmetrically positioned around the center axis of the nozzle.
5. A spray nozzle as set forth in claim 1 in which the front surface grooves are circles.
