    This application claims the benefit of US Patent Application No. 13 / 927,957, filed Jun. 26, 2013, the entire contents of which are incorporated herein by cross reference.
    [0002] This invention relates to sprinklers that are particularly suitable for agricultural sprinklers that are used but are not limited to circular irrigation machines.
    GENERAL PRIOR ART
    Circular irrigation machines have long truss sections carried by wheeled towers which rotate about a central tower. The trusses have many sprinklers along the length of the sections, either directly or suspended from the traverses on rigid or flexible drip hoses.
    Since sprinklers of this type (and in particular the sprinkler nozzles) are often exposed to unfiltered or poorly filtered water containing sand, dirt, debris, etc., it is necessary that the individual sprinklers, including the holes of the sprinkler nozzles regularly to clean or rinse. At the same time, it is necessary to install nozzles of different opening size along the length of the truss sections to obtain the desired flow rate, given the different circular diameters on which the individual sprinklers move as the machine rotates about its central tower. Rinsing and / or changing the nozzle size generally requires at least some disassembly of the sprinkler (and possibly machine shutdown), which, extrapolated to-tens or hundreds of sprinklers, is labor-intensive, time-consuming and thus expensive.
    The present invention has the purpose of simplifying the operations of replacing and / or rinsing nozzles by providing a multi-functional, laterally insertable nozzle insert which (1) can be easily installed and removed, thereby facilitating the replacement of nozzles becomes; and (2) when installed, is rotatable between different operating positions, for example "INSERT", "ON", "OFF", "NOZZLE RINSE" and "LINE RINSE".

    DETAILED DESCRIPTION OF THE DRAWINGS
    FIG. 1 shows a sprinkler assembly 10 having a sprinkler body 12 and a nozzle insert 14 receivable in a sideways complementary recess 16 provided in the sprinkler body 12. On the sprinkler body, a conventional adapter 18 is attached by means of a threaded coupling to the upstream end 20 of the sprinkler body 12. At the downstream end 24 of the sprinkler body are provided a plurality of support struts 22, the support struts being connected to a mounting ring 26 which is adapted to secure a conventional water deflector or distribution plate 28 formed with grooves 30 which typically cause the support struts Plate rotates when a jet emanating from the sprinkler nozzle impinges on it. The plate 28 may include an otherwise conventional viscosity brake or speed reduction device 32.
    Before the nozzle insert 14 and the sprinkler body 12 are described in detail, it is important to note that each use of relative position terms such as "upper (r / s)", "lower (r / s)", " left (r / s) "," right (r / s) "," front (r / s) "and" rear (r / s) ", refers to the sprinkler body and the nozzle insert, as these in the various Figures are aligned, and should not be limiting in any way, since the sprinkler can be oriented differently in use. However, since the sprinkler is generally as shown in FIG. 1 or an inverted (inverted) orientation, it is convenient to refer the nozzle insert 14 to a "side-mountable" nozzle insert.
    It is further shown in FIG. 1, but also specifically to FIG. 2-4 reference; the nozzle insert 14 is formed as a substantially cylindrical body (referred to herein as an "insert body") 34 which is preferably injection molded from a hard plastic material such as PVC (or made from another suitable plastic or metal material). The insert body 34 has a longitudinal central axis or axis of rotation A (FIG.2), also referred to herein as the "insert axis", which when inserted into the
    The sprinkler body is installed perpendicular to a longitudinal central axis B (FIG. 1) of the sprinkler body, which is also referred to herein as the "sprinkler axis". The insert body need not, in some variations of the invention, be arranged such that the axes intersect at right angles, and may instead be, for example, skewed or laterally offset as long as it is positioned to intersect the water flow path.
    The insert body 34 is formed with a nozzle bore 36, which in the illustrated variant extends transversely to the insert axis A from an inlet end 38 to an outlet end or a nozzle opening 40. As shown in FIG. 2 and 11, the nozzle bore 36 is comprised of a relatively larger diameter straight section 42 extending from the inlet end 38 and an inwardly tapered section 44 extending from a location approximately midway extends between the inlet end and the outlet end to the smaller diameter nozzle opening 40.
    A "flushing trough" 46 (FIG.3) is formed in a first continuous peripheral portion 48 of the insert body, circumferentially between the nozzle inlet 38 and the nozzle opening 40, and parallel to the insert axis A and perpendicular to the insert Nozzle bore 36 extends. The flushing trough 46 has an inlet end 50 and extends substantially axially to an open outlet end 52 at the rear end 54 of the insert body 34, as shown in FIG. 3 and 4 is best seen. The flushing trough 46 communicates with a flow channel of the sprinkler body when the nozzle insert is rotated to the "LINE FLUSHING" position, as described hereinbelow.
    A second continuous peripheral portion 56 (Figure 4) of the insert body 34 diametrically opposed to the first continuous peripheral portion 48 provides a shut-off surface when the nozzle insert 14 is rotated to the "OFF" position, as here also below is described.
    The nozzle insert 14 is also formed with a front disc-like end surface 58 (FIGS. 1-3) which, in the exemplary embodiment, has a circular shape with a diameter greater than the diameter of the remainder of the insert body 34 , The front end surface 58 is formed or provided with a relatively narrow but easy-to-grip knob 60 which extends centrally across the end surface 58 and through the insert axis A. As shown, the rotary knob 60 is tapered to a rounded point 62 at one end and thus also serves as a pointing device indicative of the rotational position of the nozzle insert 14, as indicated by positional designations, e.g. ON, OFF, NOZZLE RINSING, and RINSING (FIGURE 1) on the sprinkler body 12 at locations corresponding to the four operating positions of the nozzle insert. To enhance this positional aspect of the rotary knob 60, an arrow-like pointer 64 may be formed within or on the knob, which is aligned to match or align with the pointing direction of the knob. Because the pointer 64 is formed as a slot in the illustrated embodiment, a standard flat-blade screwdriver may be introduced in situations where additional torque may be required due to ingress of sand, etc. There may also be a number for designating the nozzle orifice size 66 (see, for example, FIGS. 1, 3, 5, and 6) on the button 60, for example above the arrow-like pointer 64, which provides the user with a clear indication of the nozzle orifice size. It should be understood that the number of nozzle orifice size designations may be located at any readily visible location on the nozzle insert 14, but preferably on the outward facing surface of the forward end surface 58 or on the button 60 itself (as shown). The nozzle inserts can also be color-coded according to aperture sizes. In addition, the arrow-like pointer 64 and the number for designating the nozzle opening size 66 may be provided in the form of separately applied adhesive labels or the like.
    It will also be understood that the front end face 58 and the ring 110 are intended to shield the user from splashes of water which may be directed at the user when the nozzle insert is rotated between its operating positions or when the nozzle insert is in the position of the nozzle NOZZLE OR LINE FLUSHING is located.
    It is also clear that other reference marks or marks may be made on the front end surface of the nozzle insert. For example, a sprinkler number corresponding to an installation location of the sprinkler along a truss section could be mounted on one side of the rotary knob 60 to help install sprinklers of correct nozzle sizes in the desired order along a truss section of a circular irrigation machine or the like. In this regard, sprinklers as described herein may be provided to the customer to be slidably mounted on a string or wire in a recommended installation order, which may be checked against the item numbers on the sprinklers.
    Behind the front end surface 58 of the insert body 34 and adjacent thereto are provided four latching projections 68, 70, 72 and 74 (Figures 2-4) which extend radially outward at 90 degree intervals around the insert body 34 , Each latching Projection Each latching projection has the shape of a rounded "U" in plan view and having a front surface 76 and a pair of spaced, substantially parallel and rearwardly extending legs 78, 80 as shown in FIG. 2 is best seen. The legs 78, 80 are beveled where they are connected to the front surface 76 to facilitate rotation of the nozzle insert, as discussed below. For convenience, the reference numerals 76, 78 and 80 are used in conjunction with each of the locking projections 68, 70, 72 and 74 because the shapes of the projections are substantially identical (with the exception noted below); However, the various numbers for the four locking projections themselves facilitate the description of the rotation of the nozzle insert 14 from a position "INSERT" by the four other latchable operating positions. It should be noted that the latching projections have similar width and radial length dimensions and similar cross-sectional shapes, with the exception of the latching projection 68, which has a greater radial length dimension than the other latching projections 70, 72 and 74.
    The rear end 54 of the insert body 34 has a rear end surface 82 and a rearwardly projecting sleeve 84 of the shape of an incomplete ring having a smaller diameter than the rear end surface 82 on. A retaining tab 86 extends radially from a rear edge of the partial annular sleeve 84 leaving an axial gap between the retaining tab 86 and the rear end surface 82. It should be noted that the retaining tab 86 is axially aligned with the locking projection 72 at the front end of the insert body.
    Between the front end surface 58 and the rear end surface 82 there are differently shaped surfaces / ribs which facilitate the shapes which serve to reinforce the insert body and / or which provide bearing surfaces when the nozzle insert 14 is installed and is rotated within the sprinkler body 12. For example, it can be seen on the nozzle bore inlet side of the insert body 34 that the bore wall 90 at the inlet end 38 (FIGS 2-4) is reinforced by radially extending ribs 92, 94, 96 extending substantially along the entire length of the body 2) extending between the front and rear end surfaces 58 and 82 respectively and between the diametrically opposed through peripheral portions 48, 56.
    The legs 78, 80 of the latching projections 68 and 72 extend, with a reduced radial height, to an inner disk-like wall 100, the outer edge of which provides a bearing surface for the insert 14 when installed in the sprinkler body is. The wall 100 has a similar diameter to the end surface 82, and this diameter is supported by the continuous sections 48, 56. A through opening 102 is formed between the nozzle bore wall 90 and the latching projections 68, 72 and thus provides space for a cord, wire or the like on which a plurality of similar nozzle inserts are slidably mounted in the desired mounting order as described above or " strung for convenient use by the customer / buyer.
    It will be understood that the position and configuration of the various reinforcing ribs are determined, at least in part, by manufacturing considerations, particularly when the insert is made of molded plastic, and in itself is not intended to limit the scope of the invention.
    It is again on FIG. 1, reference is made; the recess 16 of the sprinkler body is defined by a substantially cylindrical wall 104 which is concentric with the insert axis A (see FIG. 2). The recess 16 is at a viewing in accordance with FIG. 1 front
    End 106 open and at a rear end 108, such as in FIG. 7 can be seen, partially closed. A ring 110 is spaced from the forward end 106 and is defined by a pair of upper ribs 112, 114 (FIGS. 1, 5, 8, 10, 11, 16) and a pair of lower ribs 116, 118 (FIGS. 13, 16), leaving an axial gap 120 between the front end 106 and the ring 110.
    The ring 110 is formed with a substantially circular opening defined by a wall 111 concentric with the cylindrical wall 104 which is interrupted by four insertion slots 122, 124, 126 and 128 which are so spaced and aligned, that they mate with the four locking projections 68, 70, 72 and 74 on the insert body 34 and receive them. It should be noted that the radial length of the insertion slot 122 is increased in order to accommodate the longer locking projection 68 can. With this arrangement, insertion of the insert body 34 into the recess 16 of the sprinkler body can be performed only with a single orientation of the insert body, namely, when the latching projection 68 is aligned with the insertion slot 122. This orientation of the nozzle insert 14 with respect to the sprinkler body 12 is referred to herein as the "INSERT" position (however, it should be noted that in the illustrated embodiment, no corresponding indicia are mounted on the ring 110). Under the slot 122, however, there is an arrow indicating a direction of rotation when installing the nozzle insert and thus also provided to indicate an initial position of the nozzle insert. After insertion, the space 120 between the ring 110 and the front end 106 of the sprinkler body 12 allows the locking projections 68, 70, 72 and 74 to rotate behind the ring 110 about the insert axis A, as will be described below. The rear of the ring 110 is provided with four radially aligned detent recesses 69, 71, 73 and 75 symmetrically disposed between the respective slots 122, 124, 126 and 128 and at locations corresponding to the operating positions "ON", "OFF". , "NOZZLE FLUSH" and "FLUSH" of the nozzle insert 14 correspond.
    As will be explained below, the latching projections 68, 70, 72 and 74 are successively received in the respective recesses 69, 71, 73 and 75 when the nozzle insert 14 is successively rotated in its four individual operating positions.
    Within the recess 16 there is a pair of substantially parallel, elongate ribs 130 extending parallel to the insert axis A, on either side of an opening 154 of the insert
    Sprinkler body and concentric with the sprinkler axis B extend inwardly along the wall 104. These ribs are axially aligned with the insert slots 122 and 124 (only one rib is visible in FIG. 1) and abut against the nozzle opening side of the bore 36 and the surface 56 on the insert body 34 during insertion at the edge of the bore wall 90 come during a subsequent rotation of the nozzle insert 14 on other surfaces, for. B. the surface 48 and the bore wall 90 on the inlet side of the nozzle bore 36 to the plant. As will be appreciated, the ribs 130 help to center the nozzle insert 14 within the recess 16 (including aligning the nozzle bore with respect to the flow channel 150 (FIG. 11) in the sprinkler body) while also minimizing surface friction during rotation of the nozzle insert.
    Near the rear end of the recess 16 there are three circumferentially spaced cam latches 136, 138, 140 and a stop tab 142 (see FIG. 22), three of which (136, 138 and 140) extend substantially axially onto insert slots 124, 122 and 128 are aligned. The fourth tab, stop tab 142, is displaced slightly in a counterclockwise direction (for example, as viewed in FIG. 6) with respect to insert slot 126 for reasons discussed below. These three cam tabs and one stop tab cooperate with the retaining tab 86 during rotation of the nozzle insert 14, as will be described below.
    As mentioned above, the rear end 104 of the recess 16 of the sprinkler body is partially closed. In particular, a pair of arcuate segment walls 144, 146 (Figure 14) adjoin a support hub 147 on the insert shaft A to receive a spring 148 (Figure 11) which is also coaxially aligned with the insert axis A and which exerts a force the insert body 34 exerts in a direction opposite to the direction of insertion. In this embodiment, the spring 148 is held on the hub 147 by a "force applicator" 149 which is snapped into the base of the hub. It is easy to see that in other variants of the invention, the force applicator 149 could be dispensed with. In fact, various spring bearing arrangements and retaining arrangements and other types of springs can be used without departing from the scope of the invention.
    The sprinkler body 12 is also provided with a flow passage 150 (FIG. 11) having a first opening 152 downstream of the adapter 18 which communicates with the inlet end 38 of the nozzle bore 36. A second opening 154 located downstream of the nozzle opening 40 is also coaxial with the sprinkler body axis B. The opening 154 is spaced from the interior of the wall 104 and the nozzle opening 40 and has a diameter larger than the opening 40 such that it provides ample room for the flow exiting the nozzle. The aperture 152 secures and retains a flexible seal 160 (described below) adapted to abut and seal against the inlet side of the nozzle bore 36.
    In addition, the sprinkler body 16 is provided with a pair of openings 156, 158 (Figure 1) formed in the wall 104 along a third axis C which intersects and is perpendicular to the axes A and B. These openings, which are preferably, but not necessarily, diametrically opposed, facilitate manual cleaning of the nozzle bore 36 when the nozzle insert 14 is rotated to the OFF position and to the POSITION RINSING position, as described below.
    FIG. Figures 23 and 24 show the gasket 160 alone. FIG. Figure 23 shows a side view of the seal 160 in a normal, uninstalled condition, assuming a substantially planar shape. FIG. FIG. 24 shows the shape assumed by the flexible gasket when installed, conforming to the circular shape of both the wall 104 and the insert body 34. The seal 160 may be characterized as a "double O-ring" seal formed by inner and outer ring portions 164, 166 joined together, a structure which provides secure attachment by means of the outer ring 166 and a deflection of the inner ring 164 to conform to the sealed surface, i. H. the area of the nozzle insert that surrounds the nozzle bore 36 at the inlet end 38 allows. In addition, the construction as a "double O-ring" is particularly advantageous in that when the nozzle insert body 34 rotates across the seal, the inner ring 164 adapts to the shape of the surface of the nozzle insert body while the rounded shape of the inner ring reduces the likelihood of excessive friction which could otherwise result in cracks or other undesirable surface erosion. At the same time, the relatively soft, flexible material ensures an effective seal with only a small compression force. Conventional ball and tap valves use hard seals where high compression loads are required to effect sealing, which then requires a relatively large and undesirable handle to overcome friction.
    FIG. Figure 25 shows the seal retainer sleeve 168 removed from the flow passage 150 in the sprinkler body. The seal retainer sleeve 168 supports the seal 160 along its outer peripheral edge 166 (see Figures 11, 17, 19 and 21) and effectively clamps the seal 160 between the retainer sleeve and the opening 152 surrounding radial flange 170. It should be noted that the lower end or edge 172 of the gasket retaining sleeve surrounding the bore 173, which forms part of the flow channel 150, is also shaped to conform to the shape of the inlet end 38 of the nozzle bore 36. As noted above, this arrangement allows the inner portion 164 of the gasket to flex as required to conform to the shape of the bend of the insert body 34 and thereby effectively prevent any leakage where the flow passage communicates with the nozzle bore , FIG. Figure 26 shows the interior of the flow channel 150, which has a flat 174 which mates with a corresponding flat 176 on the seal retainer sleeve 168, which facilitates proper alignment of the sleeve within the flow channel. It should be noted that the seal retainer sleeve 168 is held in place by the adapter 18 and an additional annular seal 178 (eg, an O-ring seal) may be inserted into a groove 18 at the lower or downstream edge of the retainer sleeve , whereby a leak at the interface sleeve / adapter is also prevented.
    FUNCTIONALITY
    It is first shown in FIG. 1, which removes the nozzle insert 14 from the sprinkler body 12 but aligns with the position INSERT. In this position or orientation, the detent projection 68 is aligned with the deployment slot 122. It can be seen that the extended radial length of the latching projection 68 coincides with the extended radial length of the inserting slot 122 in the ring 110, thus allowing full insertion of the nozzle insert 14 into the complementary recess 16 of the sprinkler body 12. FIG. FIGS. 5, 6 and 7 show the nozzle insert 14 completely inserted into the sprinkler body 12.
    In this case, the latching projection 68 has moved through the insertion slot 122; the locking projection 70 has moved through the insertion slot 124; the latching projection 72 has moved through the insertion slot 126; and the latching projection 74 has moved through the insertion slot 128. When fully inserted, the retaining tab 86 is adjacent and abutting adjacent the stop tab 142 (FIG. 7), whereby rotation of the nozzle insert 14 from the INSERT position is counterclockwise, as viewed in FIG. 1, 5 and 6, is prevented.
    The coil spring 148 exerts a force on the nozzle insert 14 in a direction opposite to the direction of insertion, so that, if the nozzle insert is not made of the in FIG. 5 and 6, the spring 148 tends to urge the nozzle insert 14 out of the recess 16 of the sprinkler body.
    FIG. 8-11 show the nozzle insert 14 after being rotated 45 degrees clockwise to the "ON" position. The nozzle bore 36 is axially aligned with the flow passage 150 and its inlet and outlet ports 152 and 154, preventing leakage around the inlet port 152 and the nozzle bore inlet 38 through the seal 160 (FIG. 11). At the outlet end (i.e., at the nozzle opening 40), no seal is required because the nozzle opening 40 has a smaller diameter than the outlet opening 154, and therefore allows the flow to pass through the opening 154 effortlessly. It should also be noted that the spring 148 continues to exert a force in a direction opposite to the direction of insertion and, therefore, when the nozzle insert 14 is turned to the "ON" position, the latching projections 68, 70, 72 and 74 engage corresponding detent recesses 69, 71, 73 and 75 on the rear or back of the ring 110 are resiliently biased. It should be noted that the dimensions of the latching projections and latching recesses are such that the chamfered edges engage the edges of the recess and thus prevent complete reception of the latching projections in the latching recesses and facilitate rotation from the operating position, even if the Spring 148 acts on the projections in the direction of the recesses (see FIGS. 10 and 11). This arrangement results in the desired stopping action at each operating position while also allowing rotation out of the respective detent recesses with the desired tactile sensation.
    FIG. 12-14 show the nozzle insert 14 after it has been rotated beyond the "ON" position by a further 45 degrees clockwise to a position between the "ON" position and the "OFF." It should be noted that because the latching projection 68 radially longer than the remaining insertion slots 124, 126 and 128, the nozzle insert 14 is retained within the recess 16 of the sprinkler body as it rotates between its various operating positions, counteracting the force exerted by the spring 148. Thus, the radially longer one slides Protrusion 68 across the radially shorter slots 124, 126, 128 as the nozzle insert rotates past the INSERT position.
    Additionally, as the nozzle insert 14 rotates between its operative positions, the rotational movement is facilitated even by the retention tab 86 abutting the cam tabs 136, 138 and 140 (Figure 14) circumferentially disposed between the various operating positions (Defined by the recesses 69, 71, 73 and 75 on the back of the ring 110). In other words, the spring pressure is released when the nozzle insert 14 between its operating positions (and thus between the recesses) rotates, since the cam effect he holding tab 86 moves the insert 14 against the spring force a little inwardly or by camming action, and thus away from the back of the ring 110. As noted above, rotation is also facilitated by the chamfered edges of the latching projections 68, 70, 72 and 74 which abut the edges of the respective recesses 69, 71, 73 and 75. These features ensure smooth and easy rotation of the nozzle insert 14 from one position to the next. It is easy to see that this same interaction occurs at each of the four operating positions.
    FIG. 15-17 show the nozzle insert after it has been rotated another 45 degrees clockwise to the "OFF" position. In this position, as shown in FIG. As best seen in FIG. 17, the continuous peripheral surface 48 on the nozzle insert body 34 engages the seal 160 and thus blocks the flow from the flow passage 150 of the sprinkler body at the orifice 152. In this position, the latching projections 68, 70, 72 and 74 are acted upon in engagement with the latching recesses 71, 73, 75 and 69, respectively.
    In the OFF position, the nozzle bore 36 is aligned with the openings 156, 158 of the sprinkler body, as shown in FIG. 16 and 17 is best seen. Accordingly, while the sprinkler is OFF, the nozzle bore 36 can be manually cleaned of any debris that has become wedged firmly in the bore and can not be removed in the NOZZLE REFUSING position described below.
    FIG. 18-19A show the nozzle insert 14 after it has been rotated 90 degrees clockwise to the "NOZZLE RINSE" position with the latching projections 68, 70, 72 and 74 in engagement with the latching recesses 73, 75, 69 and 71, respectively (partially shown in FIG. 19). FIG. Figure 19 also shows how the nozzle bore 36 is now completely inverted (or reversed) relative to its orientation in the "on" position of the nozzle so that the flow of water through the smaller diameter aperture 40 enters the nozzle bore 36 and propagates through the remaining length of the bore, flushing foreign matter through the larger diameter inlet end 38. In the SPRAY position, the seal 160 abuts only a portion of the surface of the nozzle bore wall 90 that surrounds the smaller diameter orifice 40. More specifically, there is a substantial clearance 161 between the seal 160 and the nozzle bore wall 90 which varies along the circumference of the seal / bore wall interface (see Figures 19 and 19A). Leaking liquid from the nozzle opening 40 through the bore wall 90 through the gap 161 provides the user with a visible indication from a great distance that the nozzle is not in the ON position. This is important because for some nozzle sizes, the user may mistakenly leave the nozzle in the NOZZLE RINSE position, creating a misdirected flow and flow rate which, if not detected quickly, may result in damage to the crops.
    FIG. 20 and 21 show the nozzle insert 14 after it has been rotated another 90 degrees clockwise to the "LINE FLUSHING" position (simply labeled "FLUSH" on the ring 110). Here, water is directed from the flow passage 150 of the sprinkler body exiting the orifice 152 into the flushing gutter 46, and the water exits the relatively large orifice 182 between the rib portions 144 and 146 at the rear end of the sprinkler body 12 (FIGS , 21). In the position LEUTUNGSSPÜLUNG the locking projections 68, 70, 72 and 74 are engaged with the recesses 75, 69, 71 and 73.
    FIG. FIG. 22 shows retaining tab 86 engaged with the opposite side of cam / stop tab 142, which is another
    Turn the nozzle insert clockwise past the LEAD RINSING position. Therefore, to move or remove the nozzle insert 14 from the RINSING position to a different operating position, it must be turned back counterclockwise as necessary to achieve the desired position.
    It should also be noted that in the LINE FLUSH position, the nozzle bore 36 is again flush with the apertures 156 and 158 in the sprinkler body, providing an additional opportunity to manually clean the nozzle bore.
    An important feature of the illustrated embodiment is the manner in which the various described design features are combined to accurately align the nozzle insert 14 in the ON position. More specifically, the centerline of the nozzle bore 36 must be positioned in the left-right direction and the front-back direction with a maximum deviation of ± 0.005 "(127 pm) from the centerline of the flow channel of the sprinkler body and must be rotational The combination of water pressure and gasket compression pushes the nozzle insert 14 (and consequently the insert body 34) against the ribs 130 thereby effecting left-right centering / Recess / Spring provides front-to-center centering and rotation-centering, and maintains a finely-balanced balance between stability and ease of use, for example, the nozzle insert must be securely positioned so that it can be easily removed by crops such as about grain halo is triggered, not accidentally moved away from the desired operating position At the same time, however, the nozzle insert has to be relatively easy to insert and turn by hand (perhaps hundreds of times a day when circular irrigation systems are first assembled or systems replaced on site). Furthermore, it is important for the user / operator to know for sure that the nozzle is properly positioned. This is accomplished by enabling the user to feel or hear the snapping or latching of the latching projections into the latching recesses as a result of the axial force exerted by the spring 148. If the operating position is changed, the user can push and rotate the nozzle insert 14 (simpler option) or just rotate (more torque required) until the rotation begins. As the user continues to rotate without depressing, the nozzle insert body 34 snaps into the next set of detent recesses. This rotation and spring action then causes accurate positioning of the nozzle insert as long as the nozzle insert is free to move axially and rotationally, thereby allowing the spring 148 to push the latching projections into the fully latched position (ie, the position in which the inclined surfaces of the latching projections are in full contact with the inclined surface of the latching recesses).
    To ensure the necessary freedom of movement of the nozzle insert, generously sized clearances between the nozzle insert and the sprinkler body are maintained wherever possible. Further, in this connection, the nozzle insert itself is shaped so as to allow water to flow past the seal 160 in the event of position changes so that penetrated sand etc. can be flushed out.
    Although the invention has been described in conjunction with the embodiment which is presently considered to be the most convenient and most preferred, it should be understood that the invention is not limited to the disclosed embodiments, but on the contrary, various modifications and equivalent arrangements should cover.
    Modified Paragraph [0073] An important feature of the illustrated embodiment is the manner and whiteness of how the various described features ofcontrast are combined to accurately align the nozzle insert 14 in the position Eid. More specifically, the center line of the Nozzle Drill '36 must be in the left-right direction and in the front-mill direction, with a deviation of 0x0.005 "[127 and non der
    3 'of the sbrinking body must be positioned, and it must be rotationally positioxiiert axis A hit a deviation of a maximum of 10.5' 'positioxiiert. The combination of water pressure and condensation pressure prints the nozzle tip 2 11 (and consequently the
    Einaatzfcorper 34} against the ribs 13.0 and thereby causes the left-Rechta-Eentrieruirg, The arrangement projection / Auzspärung / spring causes the front Hintexr · centering And the rotation related Eentrieruxxg. In addition, a finely balanced equilibrium between stability and serviceability must be maintained. For example, the nozzle insert must be securely positioned so that it is not unintentionally moved away from the desired operating position as it is impacted by attachment ripples such as cage halves However, the nozzle assembly has to engage and rotate relatively easily, possibly hundreds of times at a time. Day when circuit backup systems are first assembled or on-site systems are exchanged, it is also important for the user / operator to know for certain that the nozzle is properly positioned. This will cause indexing of the bexintzer to snap into place or when the East projections snap into the recesses as a result of the axial force exerted by the shader 148, or heard, racing is changed, the .Begattet the nozzle insert 14 press and turn {simpler option} or only turn {more Torque Required '} until potation begins. When the user subsequently attempts to rotate without depressing, the nozzle body 3 "snaps into the next set of seats. This rotation and the setting of the seat then cause an accurate one
    Positioning the device set so that the nozzle insert is free to move axially and rotationally, thereby allowing the spring 148 to push the latching protrusion to the fully latched position (i.e., the position where the oblique smells of the
