Definitions
- the invention relates to a nozzle for discharging a liquid and devices with such a nozzle
- a shower fitting is known from DE 30 44 310 C2, in which several nozzles made of rubber-elastic material are rigidly mounted on the nozzle side and with their nozzle-side end sections are made in openings in a rotatable housing plate.
- the nozzle sections are elastically deformed under the nozzle deformation under the nozzle deformation and thereby changing the jet directions.
- the nozzle shape is composed of a tubular cylindrical nozzle section and a hollow truncated cone nozzle section which merge into one another along a circular surface line
- the jet shaping of the individual jets of the individual nozzles is of secondary importance in the intended application of a shower fitting.
- the jet shaping properties of the known nozzle are not sufficient Tilting is limited to small tilting angles due to the risk of the nozzle kinking
- a sprinkling device is known from WO 95/17262 A2, in which a group of individual rubber-elastic nozzles is collectively adjustable and at a short distance from the nozzle outlets the individual jets to the individual jets unite to form a common jet. Due to the explicit goal of combining the individual beams into a common beam, close bundling of the individual partial beams is neither necessary nor desirable.
- the nozzles are tubular and show no particularly pronounced beam bundling of the individual partial jets.
- the object of the present invention is to provide a versatile nozzle for discharging a liquid, in particular with variable jet parameters and / or with a good jet throw, and a device with such a nozzle.
- Nozzles according to the invention are specified in claims 1, 13, 21 and 24, devices with such nozzles in claims 26 and 28.
- the subclaims contain advantageous refinements and developments of the invention.
- the designation of a central area between an inlet area and an outlet area that is specially designed for a changeability of the jet parameters flow cross-section and / or deflection of the main flow direction advantageously enables the nozzle to be anchored with a foot area in a housing and / or the jet formation independent of the change in the aforementioned parameters by the Exit area and at the same time a high degree of flexibility in the direction of the jet or in influencing the flow of liquid.
- Of particular importance is the independence of the beam shaping from influencing the beam parameters mentioned, in particular for changing the Jet direction of a nozzle by deflecting the main flow direction in the central region compared to a course of the main flow direction that is preferably straight in the initial state of the nozzle.
- the change in direction of the main flow direction preferably takes place at least approximately exclusively, in particular to more than 90% of the change in direction of the ejected jet in the central region.
- the central region can advantageously have a lower transverse stiffness than the outlet region, in particular a lower bending stiffness for a deflection force acting in the region of the nozzle outlet.
- the central region can be dimensionally stabilized by means of stiffening means, in particular stiffening sleeves or the like which are in contact with the inside and / or outside.
- the central region and the outlet region can consist of different materials in such a way that the outlet region is made of more dimensionally stable material, but the nozzle can nevertheless advantageously be produced as a casting, in particular an injection molding, according to known manufacturing processes. It is particularly advantageous when the nozzle is made of material that is homogeneous, increasing the nozzle wall thickness at the transition from the central region to the outlet region, so that a shape stabilization of the outlet region by the higher of the
- the exit region can also be given a form of stability by the means used in a device for deflecting the beam direction, in that they are designed as guides for the exit region.
- the nozzle channel in the central region has a continuously decreasing cross-sectional area in the main flow direction, which preferably shows a degressively decreasing profile and advantageously continuously in the cross section of the nozzle channel in the Exit area merges
- the smallest cross section of the nozzle channel in the middle area should not be smaller and the largest nozzle channel cross section in the middle area should be at least 3 times larger than the smallest nozzle channel cross section in the exit area.
- the middle area is shaped and dimensioned such that even when deflected
- Main flow direction by up to 45 ° the smallest cross-sectional area over the entire course of the central area along the then curved main flow direction is not less than and the largest cross-sectional area of the central area is at least twice as large as the smallest cross-sectional area of the nozzle channel in the outlet area.
- the nozzle is at least in the central area and exit area in the initial state, preferably rotationally symmetrical with respect to the then main flow direction
- a force applied at the outlet area or at the transition from the middle area to the outlet area is preferably used to deflect the main flow direction, which force, when the deflecting means is designed as a guide for the exit area, at the same time force a defined changed orientation of the outlet area
- a larger cross-sectional area with the same cross-sectional shape is associated with a larger circumferential area of the nozzle channel section, which, after the clamping device has been reset, has a favorable effect on the rapid and reliable expansion of the nozzle channel through the liquid pressure, even after a longer disconnected state in the section provided for clamping in the initial state of the nozzle advantageously at least 3 times, in particular at least 6 times the smallest cross-sectional area of the nozzle channel in the outlet area
- the middle part of the nozzle preferably extends over at least 20%, in particular at least 33%, of the total nozzle channel length.
- a notch is advantageously provided in the course of the outer contour of the nozzle, with which the nozzle is held in a self-retaining manner Housing opening can be used
- a calming area which obstructs circular flow components, takes advantage of the knowledge that beam bundling is impaired in particular by such circular flow components of fluid movement and eliminates essential sources of influence of such flow components
- Entry area of the nozzle channel is particularly important in arrangements in which the main flow of the liquid supply inside a device is directed transversely to the orientation of the nozzle channel and the Liquid to flow into the nozzle channel undergoes a change in direction of approximately between 45 ° and 135 °. Such a change in direction leads to uneven flow and eddies with circular movement components that can continue until the nozzle exits, in particular also through a jet-shaping nozzle area
- An advantageous measure according to the invention therefore provides for a calming area to be provided in the course of the nozzle channel in front of an outlet area, which can be provided in particular for beam shaping and preferably may have a cylindrical shape, which is designed to impede circular flows.
- circular movement components perpendicular to the main flow direction of the The nozzle channel can be reduced with little effort and good effect, advantageously by reducing the space for free circular movements in planes perpendicular to the main flow in the cross section of the nozzle channel, preferably by designing the cross section of the nozzle channel in such a way that the largest free circular area within the cross-sectional area is significantly smaller than the total cross-sectional area, in particular less than 20% of the cross-sectional area.
- a preferred embodiment provides that guide elements oriented from the walls towards the center of the nozzle channel with guide surfaces parallel to the main flow channel are arranged in the calming area. These guide elements preferably extend from the wall of the nozzle channel and are connected to it, so that the guide elements are mechanically stable even with a low material strength are arranged
- the cross section of the nozzle channel segmented by the guide elements can also have the circular shape which is customary per se.
- the guide elements are preferably at the one another and the center of the
- the edges facing the nozzle channel are spaced so that a clear interior space remains free in the middle of the nozzle channel.
- the clear interior space which advantageously lies in the direct extension of the preferably cylindrical nozzle channel section of the nozzle area, favors the unimpeded flow in the main flow, but can be avoided by
- the area of the free circular cross-section of the clear interior advantageously lies between 1 times and 20 times, preferably between 2 times and 10 times the value of the smallest cross-sectional area of the nozzle channel in the Dusenaust ⁇ tts Colour
- the nozzle area advantageously comprises a cylindrical, in particular circular cylindrical nozzle section, as is known per se from the prior art.
- the length of this nozzle section is advantageously substantially larger than the diameter of the cylindrical section and is preferably between 5% and 60%, in particular between 15% and 35 % of the total length of the nozzle channel.
- the nozzle channel preferably has its smallest cross-sectional area in this cylindrical nozzle channel section The cross-sectional area of the nozzle channel preferably decreases steadily in the main flow direction until it reaches its smallest value on the cylindrical nozzle channel section of the nozzle outlet area.
- the cross-section is advantageously reduced with as little disturbance of the flow as possible smaller values are limited and / or the directional change of the surface lines on curved sections, represented by tangents, is limited to less than 15 ° to 5% of the nozzle channel length in the main flow direction Main flow direction after the calming area can be avoided.
- the calming area of the nozzle channel advantageously begins at or near the opening into the nozzle Enraum is preferably designed with a largely constant cross-section, ie constant distances between the guide elements in the main flow direction
- a middle area is provided between the calming area and the nozzle area, which preferably shows a lower transverse stiffness of the nozzle channel wall takes place in the central area and in particular the jet-shaping nozzle area remains largely undeformed, and on the other hand that in this central area a specific cord-off of the nozzle channel is achieved
- the former is particularly important for applications in which a jet radiation variation and / or in the case of a plurality of nozzles an individually different jet orientation of the individual nozzles is intended in the case of fixed nozzle outlets oriented in parallel.
- the latter is advantageous, for example, for a targeted shutdown of the liquid discharge from a jet
- a further measure according to the invention provides for a separation point of the multi-part tool and thus a more or less pronounced casting seam at the separation point to a position within the nozzle channel in the main flow direction in front of the cylindrical Laying the nozzle channel section
- the separation point of the casting tool which runs transversely to the main flow then leads to an annular casting seam on the wall of the nozzle channel.
- the casting seam of the wall of the nozzle channel or the separating point of the tool on which this is based is preferably at a position where the cross-sectional area of the nozzle channel is between 1.5 and 4 times, in particular between 2 times and 3 times smallest cross-sectional area of the nozzle exit area.
- the tool part which extends from the nozzle end to form the later nozzle outlet channel to the opposite tool to the point of separation, essentially shows the shape of a pin extending from a base point, which widens at its end remote from the base point.
- the mechanical stresses occurring in the tool provided for producing the nozzle can be distributed and limited to harmless values .
- a clean jet separation from the nozzle wall is not impaired, in particular with radii of curvature of less than 1 mm.
- the nozzle Since the pin of the tool in the cast nozzle is supported on the one hand at the base point on the end face of the nozzle and on the other hand the expansion of the pin facing away from the base point engages behind the narrower cylindrical nozzle channel section, the nozzle must be demolded by the tool pin.
- the rubber-elastic nozzle material enables the separation point at the preferred cross-sectional area ratios and narrowest Düsendka ⁇ alquer bain such forced demolding without risk of damage to the nozzle or tool
- the nozzle according to the invention can be used in a device for discharging a liquid, in which the nozzle device is elastically bent over in relation to a fixed nozzle device in order to achieve a specific alignment of the emerging jet.
- the device preferably contains a plurality of such nozzles, so that a nozzle fan can be generated with different and preferably variable jet orientations
- a further advantageous application of a nozzle according to the invention provides a device for discharging a liquid, in which devices for constricting the nozzle channel between the nozzle insert and the nozzle outlet are provided. In this way, the water outlet can be shut off from the nozzle with little effort and reliably a plurality of nozzles are provided in the device
- Fig. 1 is a side view of a nozzle
- FIG. 2 shows a longitudinal section through the nozzle of FIG. 1
- FIG. 3 shows a view of the Dusenkanal from the Duseneint ⁇ tt Fig. 4 is a deflected nozzle
- Fig. 5 is a clamped nozzle
- the nozzle body extends from a foot part F integrated into a plate P with increasing slimming in the main flow direction H to the nozzle end surface FE.
- the outer contour of the nozzle has a notch K, which is provided for engaging in a housing opening with overlapping on both sides of the edge of such a housing opening.
- the notch can also have a circumferential rib T for more reliable sealing of the housing opening by the nozzle body used.
- the plate P can advantageously connect a plurality of nozzles to one another in a preferably linear arrangement. Liquid flowing in through the nozzle inlet DE is accelerated in the course of the nozzle due to the narrowing inner cross section and emerges from the nozzle in the main flow direction H as a narrowly focused jet through the nozzle outlet DA.
- the liquid-carrying nozzle channel which extends in the interior of the nozzle from the nozzle inlet to the nozzle outlet, is assumed to be rotationally symmetrical with respect to a central axis.
- the cross section of the nozzle channel narrows continuously from the nozzle inlet DE to a circular cylindrical nozzle channel section ZK of a nozzle outlet region DA.
- the nozzle channel has its smallest cross section in this section ZK.
- the constriction of the nozzle channel cross section takes place without abrupt transitions, so that the generation of movement components of the liquid within the nozzle channel, which disrupt the beam bundling, is minimized
- the surface lines of the wall W1 of the nozzle channel lying in the plane of the drawing are predominantly formed by several essentially straight sections which merge with one another with generous radii of curvature with only slight changes in angle with respect to the main flow direction H.
- the surface lines run in one direction towards the inlet of the nozzle lower plate level parallel alignment For the guidance of the surface lines there is a large variability in detail
- Calming area B is provided with a plurality of guide elements LE in the form of lamellae which extend from the nozzle channel wall in the direction of the center of the nozzle channel.
- the guide elements LE segment the flow area of the nozzle channel and hinder circular movement parts of the liquid in planes perpendicular to the
- Main flow direction which can be expressed by superimposition with the movement in the main flow direction in the form of spiral movement patterns.
- the majority of such circular flows are prevented by slats which run transversely to flow lines of such circular movement components.
- the slats do not run to the middle of the nozzle channel, but are among one another and from spaced from and delimiting a clear interior space IR with a free circular cross-section DI, which is substantially smaller than the diameter of the nozzle area DE.
- the length of the calming area B is preferably at least 20% of the total length of the nozzle channel from the nozzle area to the nozzle area A nozzle area A comprises a cylindrical, in particular circular cylindrical, nozzle channel section ZK which significantly influences the jet formation.
- the wall W1 of the nozzle channel merges into a curve R, which leads to the nozzle end surface FE.
- the curve R causes mechanical stresses on the injection molding tool which is preferably used for the production in the injection molding tool Area of the nozzle outlet distributed and peak loads avoided.
- the beam separation when leaving the nozzle outlet proves to be uncritical, so that the rounding R does not noticeably impair the beam formation
- the nozzle has a central region M between the inlet region E and the nozzle outlet region A, in which the flow rate of the liquid increases steadily due to the continuous narrowing of the cross-section in the main flow direction. In each case there may be short distances between the inlet region, the central region and the outlet region
- the nozzle shows a wall thickness, which preferably decreases continuously in the main flow and increases again during the transition to the subsequent exit area.
- a deflection of the exit area to deflect the A jet from the central axis of the starting position of the nozzle causes a deformation of the nozzle body p ⁇ mar in the central region, whereas the cylindrical nozzle channel section ZK of the nozzle outlet region A remains essentially undeformed with such a deflection and therefore the jet formation is not significantly influenced by the deflection.
- the foot region of the nozzle is considered as firmly anchored in a housing when the nozzle end is deflected to deflect the jet In FIG.
- the nozzle shown in FIG. 2 in the starting position is sketched in a position with a deflected jet exit direction.
- Deflection means UM attached to the exit area are designed as a guide for the exit area at least in the direction of the deflection.
- the change in direction of the main flow in the jet exit towards H 'takes place essentially exclusively takes place in the middle area, whereas the exit area remains essentially undeformed due to the guidance by the deflecting means and / or the higher wall thickness of the exit area and therefore retains its advantageous beam shaping properties.
- the cross-sectional area of the nozzle channel remains elliptical even when the middle area is bent from the circular shape deformed cross-sections larger than the cross-sectional area in the jet-forming exit area, so that the flow remains essentially unchanged by the cross-section of the exit area
- FIG. 5 shows a nozzle of the type outlined in FIG. 2, in which, in a section of the central region facing the inlet area E, an external clamping device KV acting transversely to the main flow direction completely constricts the nozzle channel.
- an external clamping device KV acting transversely to the main flow direction completely constricts the nozzle channel.
- intermediate positions of the clamping device may also be possible
- a longer cord of the nozzle channel may not be sufficient to reset the nozzle material.
- the pressure of the liquid then also acts in the direction of not producing the original nozzle channel cross-section, the restoring force being greater due to the larger wall area in an area with the initial state
- the nozzle is preferably made as a material-homogeneous injection molded part made of rubber-elastic material. In the casting process with the multi-part casting tool, more or less pronounced casting seams, which can also continue in irregular casting skin, can hardly be avoided at separating points of the tool.
- the invention is not limited to the exemplary embodiments described, but in a number of ways within the scope of specialist skill changeable.
- the course of the nozzle channel can deviate from the sketched shape of the surface lines in many ways.
