The spray nozzle 10 further includes means for retaining the orifice plate 14 and swirl unit 16 within the carrier 12. In the preferred embedment of the invention, the means for retaining includes a pair of retaining lugs or like retaining members 34 formed adjacent to the opposite end of the second locating bore 28 relative to the first locating bore 26. As shown typically in FIG. 12, the two retaining lugs 34 are angularly spaced relative to each other and project inwardly a predetermined distance “d1”. As shown in FIG. 4, each retaining lug 34 defines an approximately planar retaining surface 41 for engaging the adjacent end surface of the swirl unit and retaining the swirl unit and orifice plate within the carrier.
As shown in FIGS. 5-8, the swirl unit 16 defines a first (or downstream) approximately planar end surface 52 engageable with the adjacent surface 44 of the orifice plate 14 received within the first locating bore 26, and a second (or upstream) approximately planar end surface 54 axially spaced relative to the first end surface. A peripheral surface 56 extends between the first and second end surfaces 52 and 54, respectively, and defines at least two locating surfaces (or surface sections) formed on approximately opposite sides of the swirl unit 16 relative to each other and dimensioned for slidably contacting the interior surface defining the second locating bore 28 upon inserting the swirl unit therein for supporting and aligning the swirl unit 16. A tapered surface, bevel or chamber 57 is formed at the junction of the peripheral surface 56 and the first end surface 52 for facilitating insertion of the swirl unit into the second locating bore 28. In the preferred embodiment, the peripheral surface 56 has a circular shape defined by a radius “R4” which is approximately equal to (but slightly less than) the second radius “R2” of the second locating bore 28, and therefore the at least two locating surface sections are formed by the continuous peripheral surface. The clearance between the radii R2 and R4 is preferably within the range of approximately 0.0035 through 0.0060 inch. As will be recognized by those skilled in the pertinent art, the peripheral surface 56 may take any of numerous different shapes and configurations, and therefore the locating surfaces (or surface sections) may likewise take other shapes and configurations for purposes of supporting and aligning the swirl unit 16 within the carrier 12.
The assembly of the nozzle 10 proceeds in two stages. The first stage shown in FIGS. 9-12 allows the o-ring 32, orifice plate 14 and swirl unit 16 to be positively located in relation to each other and fixedly secure and aligned within the carrier 12, and the second stage shown in FIG. 1 completes the assembly with the nozzle body 18 fixedly secured within the carrier behind the swirl unit and orifice plate. To begin the first stage of assembly, and with reference to FIG. 9, the o-ring 32 is inserted into the groove 30 of the carrier 12 and the orifice plate 14 is inserted within the first locating bore 26 behind the o-ring. The chamber 51 guides the orifice plate into position so that the radius R3 of the peripheral surface 50 will locate the orifice plate concentrically within the carrier. Next, as shown in FIG. 10, the recessed surface or flat 58 of the swirl unit 16 is aligned with the retaining lugs 34 of the carrier and the swirl unit is inserted into the guide bore 38 and second locating bore 28 until the first end surface 52 thereof contacts the orifice plate 14. At this point, the second end surface 54 of the swirl unit is not in clearance of the retaining surfaces 41 of the retaining lugs 34. Accordingly, a screw driver or like tool (not shown) is then inserted into the slot 68 forming the tool-engaging surface of the swirl unit 16, and sufficient axial force is imparted by the screw driver to compress the o-ring 32 and in turn cause the swirl unit to move further into the first locating bore 28 until the second end surface 54 of the swirl unit is in clearance to the retaining surfaces 41 of the retaining lugs 34. Then, as shown in FIG. 12, the screw driver and swirl unit 16 are rotated approximately 90° in order to move the flat 58 of the swirl unit out of alignment with the retaining lugs 34. The axial force of the screw driver is then released, allowing the o-ring 32 to expand and move the swirl unit 16 until its second end surface 54 engages the retaining surfaces 41 of the retaining lugs 34. As shown in FIGS. 11 and 12, the carrier 12, o-ring 32, orifice plate 14, and swirl unit 16 are then locked in a subassembly that can be turned in any direction without the o-ring, orifice plate and swirl unit falling out of the carrier.
In FIGS. 17-20 another spray nozzle embodying the present invention is indicated generally by the reference number 210. The spray nozzle 210 is substantially the same as the spray nozzles 10 and 110 described above, and therefore like reference numerals preceded by the numeral “2”, or preceded by the numeral “2” instead of the numeral “1”, are used to indicate like elements. The primary difference between the spray nozzle 210 and the spray nozzles described above is that the spray nozzle 210 does not include the retaining lugs or like retaining members 34, 134 to retain the swirl unit 216 and orifice plate 214 within the carrier 212. Rather, the swirl unit and orifice plate are fixedly secured within the carrier by the nozzle body 218 upon threadedly securing the nozzle body within the carrier. Otherwise, the nozzle body, carrier, swirl unit and orifice plate are essentially the same as the corresponding components in one or more of the above-described embodiments of the invention.
In FIGS. 21 and 22 another spray nozzle embodying the present invention is indicated generally by the reference numeral 310. The spray nozzle 310 is substantially the same as the spray nozzle 210 described above, and therefore like reference numerals preceded by the numeral “3” instead of the numeral “2” are used to indicate like elements. The primary difference between the spray nozzle 310 and the spray nozzles described above is that the carrier is formed in two parts, 312A and 312B. As shown, the first carrier part 312A includes the above-described features for receiving the swirl unit 316, orifice plate 314 and o-ring 332, and the second carrier part 312B includes the above-described features for threadedly retaining the nozzle body (not shown) within the carrier. The first carrier part 312A defines an outwardly projecting lip 390, and the second carrier part 312B defines a corresponding inwardly projecting lip 392. The nozzle 310 is assembled by slidably moving the first carrier part 312A into the second carrier part 312B until the corresponding lips 390, 392 engage one another to thereby seat the first carrier part within the second carrier part, as illustrated in FIG. 21. The swirl unit 316, orifice plate 314 and o-ring 332 may be installed within the first carrier part 312A either before or after insertion of the first carrier part into the second carrier part. Then, the components of the nozzle assembly are fixedly secured together by threadedly receiving the nozzle body (not shown) within the first and second carrier parts in the same manner that the nozzle body 218 is threadedly received within the carrier 212 of nozzle 210 as described above.
