Definitions
- the present invention relates to spray nozzles of liquid, capable of being used in the most more diverse such as for example spray pumps, vaporizers, nozzles for combustion burners, internal combustion engine injectors.
- the invention applies more particularly to the nozzles of spray into which the liquid to be sprayed is fed in a central channel swirling through channels side of fluid intake tangentially injecting the liquid which then leaves the central vortex chamber by a coaxial output passage.
- Central chamber spray nozzles swirling generally ensures good spraying of the liquid.
- nozzles are usually made of metal, by traditional machining processes, and most often involve a nozzle hollow body, with a peripheral external wall of axis longitudinal, and with a radial anterior outer wall provided an axial outlet hole for the flow of the outlet flow from fluid.
- the central swirl chamber is limited by a peripheral wall of revolution of longitudinal axis, by a wall anterior to coaxial outlet passage, and through a wall later.
- the anterior wall with coaxial outlet passage is formed by said radial anterior outer wall, perpendicular to the longitudinal axis.
- At least one lateral intake channel of fluid is provided in the peripheral wall, open in the chamber swirl center, and shaped for flow flow fluid inlet and to tangentially inject the fluid into the central swirl chamber.
- the spray nozzles produce an output stream in the form of liquid sprayed in fine droplets, the flow being generally conical along the axis longitudinal, and the droplets distributed in the cone of randomly.
- the dispersions of the output flow parameters of the liquid are due to a dispersion of the dimensions of the channels of fluid intake, and especially of the central chamber of swirling. It is not economically possible to reduce these dimensional dispersions with the methods of traditional manufacturing machining of metal parts constituting known spray nozzles, as this would require great machining precision which is not economically feasible, especially in the case of reduced size spray.
- the anterior plate and the posterior nucleus are all two held laterally independently of each other by the wall nozzle body device.
- This added front plate structure does not allow however not to achieve economically and reproducibly in series of spray nozzles with a rear recess coaxial extending backward into the posterior nucleus the swirl chamber.
- Such a coaxial posterior recess may have a advantage in particular for stabilizing the projection cone at the outlet nozzle.
- the problem proposed by the present invention is to design a new chamber spray nozzle structure swirl center which can be manufactured in such a way economical and precise by implementing techniques of great precision, so that the fluid intake channels and the central swirl chamber are dimensioned so precise and repetitive, and so as to precisely center a posterior swirl chamber recess.
- the invention aims in particular to produce such nozzles of small dimensions, in which the channels fluid inlet and central swirl chamber are reduced in size, so that the dimensional accuracy necessary lead to absolute details of the order of just a few microns.
- Another problem proposed by the invention is to avoid the risks of degradation of the spray nozzle in the event of cold solidification of the fluid contained in the spray nozzle.
- the relative centering means of the plates are made on their front support faces respectively.
- the relative centering means of the platelets include a posterior peripheral rib of the front plate into which the periphery of the posterior plate.
- a spray nozzle according to the present invention comprises a hollow body for nozzle 1, for example a hollow body cylindrical, limited by a peripheral external wall 2 of axis longitudinal I-I and of revolution, and closed by an external wall radial anterior 3 provided with an axial outlet hole 4.
- a posterior core 5 is fitted in the hollow body of nozzle 1, with peripheral channels 6 and 7 for supplying fluid up to one or more peripheral anterior cavities 8, 8a and 8b. There is provision for access between the posterior nucleus 5 and the radial anterior outer wall 3, either by providing a reported radial anterior outer wall 3, either by providing a posterior nucleus 5 reported.
- the posterior nucleus 5 is reported in the hollow body of nozzle 1, while the radial front wall 3 is in one piece with the peripheral external wall 2.
- the spray nozzle according to the invention comprises in in addition to a central swirl chamber 9, limited by a peripheral wall 10 of revolution with longitudinal axis I-I, by a front wall 11 with coaxial outlet passage 12 for driving the fluid outlet flow, and through a rear wall 13.
- the central swirl chamber 9 is connected to the one or more peripheral anterior cavities 8, 8a and 8b by at least one channel side of fluid inlet 14, open in the central chamber swirl 9, and shaped to drive the input flow of fluid and to tangentially inject the fluid into the central swirl chamber 9, for example according to a direction substantially perpendicular to the longitudinal axis I-I.
- the axial outlet hole 4 of the radial anterior outer wall 3 is oversized, i.e. the coaxial outlet passage 12 of the spray nozzle is smaller than the axial outlet hole 4.
- the peripheral walls 10 and anterior 11 of the chamber swirl center 9, the coaxial outlet passage 12 and said at least one lateral fluid intake channel 14 are formed by grooves and recesses made with precision in an anterior plate 15 added in the hollow body of the nozzle 1.
- the added front plate 15 is pressed against the posterior face of the radial anterior outer wall 3 of the nozzle hollow body 1, and is pierced with an axial hole constituting the coaxial outlet passage 12.
- the front plate 15 is provided posterior grooves forming said at least one lateral channel fluid inlet 14, and is provided with a posterior recess axial constituting the central swirl chamber 9.
- the front plate 15 is shaped to achieve a plurality of lateral intake channels, for example provided with three posterior grooves 14, 14a and 14b constituting three channels intake side regularly distributed around the periphery of the central swirl chamber 9, and constituting the three peripheral anterior cavities 8, 8a and 8b.
- the posterior nucleus 5 limits, by its anterior face 16, said at least one lateral fluid intake channel 14 and said central swirl chamber 9.
- the front face 16 of the posterior core 5 includes an axial posterior hollow 17, facing of the coaxial outlet passage 12, extending backwards the central swirl chamber 9 having a section transverse weaker than the swirl chamber 9.
- the centering of the front plate 15 in the hollow nozzle body 1 is provided by the periphery of the front plate 15 which engages with little or no play in the cylindrical bore limited by the peripheral external wall 2 of the hollow body of nozzle 1.
- the front plate 15 may include, on its front side, a coaxial circular rib forming a lip surrounding the coaxial outlet passage 12, said rib being engaged substantially without play in the axial outlet hole 4 of the radial anterior outer wall 3 of the hollow nozzle body 1 to ensure its centering.
- the front plate 15 is pressed between the wall external anterior radial 3 and the posterior nucleus 5, which is itself held in the hollow body of nozzle 1 by fixing means, for example by screwing into a threaded section 100 of the hollow body 1 shown in Figure 1.
- the posterior nucleus 5 comprises a posterior nucleus body Sa, retained in the hollow body of nozzle 1 by the fixing means previously mentioned, and a posterior plate 5b maintained by the posterior core body 5a bearing against the plate anterior 15.
- the posterior plate 5b forms the wall posterior 13 of central swirl chamber 9 and limit backwards said at least one lateral intake channel of fluid 14.
- the rear plate 5b comprises, according to the longitudinal axis, an axial hole constituting said hollow posterior 17 with smaller cross section than the chamber swirl center 9, extending said central chamber backward swirl 9.
- the anterior plates 15 and posterior 5b are provided relative centering means for ensuring their relative centering one in relation to the other.
- Such relative centering means may consist of male - female engagement means formed in respective positions on the two pads. In the extent that the wafers can be produced by means precise manufacturing, it is important that the centering means are also provided on the pads themselves.
- At least one of the anterior and posterior plates 15 5b is mounted with a radial clearance in the hollow body of the nozzle, by example the peripheral radial clearance 24 around the wafer posterior 5b. In this way, the relative centering of the plates 15 and 5b is assured with certainty and with great precision. It follows that the posterior recess 17 is perfectly coaxial with the swirl chamber and with the passage coaxial output 12.
- the means relative centering plates 15 and 5b include a rib posterior device 20 of the anterior plate 15 in which engages at least partially the periphery 21 of the posterior plate 5b.
- the two plates 15 and 5b are pressed axially both between the radial anterior outer wall 3 and the posterior nucleus body Sa.
- the front plate 15 is centered in the hollow body nozzle 1 by its periphery engaging with little or no play in the cylindrical bore limited by the peripheral external wall 2. Alternatively, centering could be provided by the periphery of the rear plate 5b engaged in the wall external peripheral 2.
- fluid supply channels are provided by grooves provided not on the front plate 15, but on the plate posterior 5b, or on the two plates 15 and 5b.
- FIGS. 2 to 5 constitute a single-stage fluid supply system, i.e. the channels fluid intake sides direct fluid from the peripheral anterior cavity 8 to the swirl 9.
- three fluid inlet channels 14, 14a and 14b are provided connecting the central swirl chamber 9 to a first common intermediate coaxial annular chamber 18, itself connected to a second intermediate coaxial annular chamber common 25 by three intermediate channels 19, 19a and 19b injecting tangentially the fluid in the first annular chamber common coaxial 18 so as to rotate the fluid in the direction opposite of its rotation in the central vortex chamber 9.
- the second common intermediate coaxial annular chamber 25 is itself connected to peripheral anterior cavities 8, 8a and 8b and to the peripheral channels 6 and 7 for supplying fluid by three intermediate channels 26, 26a and 26b injecting tangentially the fluid in the second annular chamber coaxial joint 25 so as to rotate it in the direction of its rotation in the central vortex chamber 9.
- the coaxial outlet passage 12 can advantageously be a section of cone whose half-angle at the top is between 0 ° and 3 °, and converges towards the exit.
- the special nozzle structure according to the invention with plates 15 and 5b attached between a body nozzle hollow 1 and a posterior core body 5a, one can separate the production of external parts (hollow body of nozzle 1 and posterior core body 5a) ensuring the mechanical strength of the nozzle, and interior parts (front plate 15 and posterior plate 5b) defining the dimensions of the channels fluid intake such as channel 14, from the central chamber swirl 9, coaxial outlet passage 12 and hollow posterior axial 17. It is then possible to produce the plate anterior 15 and the posterior plate 5b of a material different from that constituting the external parts 1 and 5, and according to different manufacturing methods, allowing great precision in the realization of the central chamber of swirl 9, coaxial outlet passage 12, and channels fluid intake such as channel 14.
- channels fluid intake such as channel 14, and a central chamber swirl 9 with coaxial outlet 12 and hollow posterior axial 17 whose dimensions are very precise, ensuring satisfactory reproducibility of the characteristics of the spray of fluid at outlet.
- a plate such as the front plate 15 generally planar, so the fluid intake channels such as channel 14 are parallel to the posterior face of front plate 15.
