Definitions
- nozzles are known for generating a fluid jet at high speed or high pulse, which are designed to pressurize the fluid jet with a pressure which is higher than the ambient pressure.
- the fluid is accelerated and / or directed or bundled.
- the nozzle is usually moved by means of a device.
- an additional device is thus required in addition to the nozzle.
- This additional device includes moving components that can easily wear out. The costs associated with manufacturing and maintenance are correspondingly high.
- Another disadvantage is that due to the movable components a relatively large overall space is required.
- the fluidic components do not include any movable components that serve to generate a motile fluid flow. As a result, they do not have the disadvantages resulting from the moving components compared to the nozzles mentioned at the outset.
- a strong pressure gradient regularly occurs in the known fluidic components within the fluidic components, so that cavitation, ie the formation of cavities (bubbles), can occur during flow through the fluidic components with a fluid fluid flow within the components.
- cavitation ie the formation of cavities (bubbles)
- the life of the components can be massively reduced or a failure of the fluidic components can be brought about.
- the known fluidic components are also more suitable for wetting surfaces than for producing a fluid jet at high speed or with a high pulse.
- a fluid flow emerging from a known fluidic component has the spray characteristic of a flat jet nozzle which generates a finely atomized jet.
- the present invention has for its object to provide a fluidic component which is designed to provide a movable fluid jet at high speed or high pressure available, wherein the fluidic component has a high reliability and a correspondingly lower maintenance.
- the fluidic component comprises a flow chamber through which a fluid flow can flow.
- the fluid stream may be a liquid stream or a gas stream.
- the flow chamber comprises an inlet opening and an outlet opening, through which the fluid flow enters the flow chamber or exits the flow chamber again.
- the fluidic component further comprises at least one means for the targeted change in direction of the fluid flow at the outlet opening, wherein the means is designed in particular for forming a spatial oscillation of the fluid flow at the outlet opening.
- the flow chamber has a main flow channel interconnecting the inlet port and the outlet port, and at least one bypass channel as the at least one means for selectively directing the fluid flow at the outlet port.
- the fluidic component is characterized in that the inlet opening has a larger cross-sectional area than the outlet opening or that the inlet opening and the outlet opening have an equal cross-sectional area.
- the cross-sectional areas of the inlet opening and the outlet opening are to be understood in each case as the smallest cross-sectional areas of the fluidic component that the fluid flow passes when it enters the flow chamber or exits the flow chamber again.
- the exiting fluid jet is also compact, that is to say that the fluid jet spatially fanned out or burst open only late (far downstream) and not directly at the outlet opening.
- Movable components for generating an oscillating beam can be dispensed with in the arrangement according to the invention, so that this does not incur costs and expenses.
- the vibration and noise development of the fluidic component according to the invention is relatively low.
- the occurrence of cavitation within the fluidic component is avoided by the inventive choice of the size ratio of inlet opening to outlet opening. Contrary to the prevailing view, the formation of the oscillating fluid jet is not affected by the outlet opening having a smaller cross-sectional area than the inlet opening.
- the spatially oscillating fluid jet emerging from the fluidic component according to the invention has a high removal and cleaning performance due to its compactness and high speed when it is directed onto a surface. Therefore, the fluidic component according to the invention can be used for example in the cleaning technique. Also for the mixing technique (in which two or more different fluids are to be mixed together) and the production technology (for example, water jet cutting), the fluidic component according to the invention is interesting. Thus, for example, the effectiveness of the water jet cutting can be increased with a leaking from the fluidic component of the invention pulsating fluid jet.
- the cross-sectional area of the inlet opening may be equal to or greater than the cross-sectional area of the outlet opening.
- the size ratio can be selected according to the desired characteristics (speed, compactness, oscillation frequency) of the outgoing beam. However, other parameters such as the size (eg, volume and / or component depth, part width, part length) of the fluidic component, the shape of the fluidic component, the type of fluid (gas, low viscosity fluid, high fluid fluid) may also be used Viscosity), the magnitude of the pressure applied to the fluidic fluid entering the fluidic component, the input velocity of the fluid, and the volumetric flow rate affect the size ratio selection.
- the oscillation frequency can be between 0.5 Hz and 30 kHz.
- a preferred frequency range is between 3 Hz and 400 Hz.
- the input pressure may be between 0.01 bar and 6000 bar above ambient pressure.
- the inlet pressure is typically between 0.01 bar and 12 bar above ambient pressure.
- high-pressure applications such as for cleaning (vehicles, semi-finished products, machinery or stables) or the mixture of two different fluids, the inlet pressure is typically between 5 bar and 300 bar.
- the cross-sectional area of the outlet opening may have any shape, such as square, rectangular, polygonal, round, oval, etc. The same applies to the cross-sectional area of the inlet opening.
- the shape of the inlet opening may correspond to the shape of the outlet opening or differ from the latter.
- a round cross-sectional area of the outlet opening may be selected to produce a particularly compact / bundled fluid jet. Such a fluid jet can be used in particular in high-pressure cleaning technology or in water-jet cutting.
- the width of inlet and outlet opening is defined with respect to the geometry of the fluidic component.
- the fluidic component may, for example, have a substantially cuboidal shape and correspondingly have a component length, a component width and a component depth, wherein the component length determines the distance between the inlet opening and the outlet opening and the component width and the component depth are each defined perpendicular to one another and to the component length, and where the component width is greater than the component depth.
- the component length thus extends substantially parallel to the main propagation direction of the fluid flow, which moves as intended from the inlet opening to the outlet opening. If the inlet and the outlet opening lie on an axis which extends parallel to the component length, then the distance between the inlet and the outlet opening corresponds to the component length.
- the fluidic component has a component depth which is constant over the entire component length.
- the component depth may decrease (steadily (with or without a constant rise) or jump) from the inlet opening to the outlet opening. Due to the decreasing component depth, the fluid jet is pre-bundled within the fluidic component, so that a compact fluid jet emerges from the fluidic component. An expansion or bursting of the fluid jet can thus be delayed and thus does not take place directly at the outlet opening, but only further downstream. This measure is advantageous, for example, in cleaning technology or in the water jet technique.
- the component depth may increase from the inlet opening to the outlet opening, wherein the component width decreases such that the cross-sectional area of the outlet opening is smaller than or equal to the cross-sectional area of the inlet opening.
- the flow chamber has at least one bypass duct.
- the bypass duct is permeable by a part of the fluid flow, the secondary flow.
- the part of the fluid flow, which does not enter the bypass duct but exits the fluidic component is referred to as the main flow.
- the at least one bypass duct may have an inlet located near the outlet opening and an outlet located near the inlet opening.
- the at least one bypass duct can be arranged in the fluid flow direction (from the inlet opening to the outlet opening) next to (not behind or in front of) the main flow duct.
- two bypass ducts can be provided which extend laterally (as viewed in the main flow direction) next to the main flow duct, the main duct being arranged between the two bypass ducts.
- the bypass ducts and the main flow duct are arranged in a row along the component width and each extend along the component length.
- the bypass ducts and the main flow duct may be arranged in a row along the component depth and each extend along the component length.
- the at least one bypass duct is separated from the main duct by a block.
- the at least one bypass duct may have a greater or lesser depth than the main duct. In this way, an additional influence on the oscillation frequency of the exiting fluid jet can be taken.
- the oscillation frequency drops when the other parameters remain essentially unchanged. Accordingly, the oscillation frequency increases when the component depth in the region of the at least one bypass duct (in comparison to the main duct) is increased and the other parameters remain essentially unchanged.
- Another way to influence the oscillation frequency of the exiting fluid jet can be provided by at least one separator, the is preferably provided at the entrance of the at least one bypass channel.
- the separator assists in splitting off the side stream from the fluid stream.
- a separator transverse to the flow direction prevailing in the bypass duct
- the separator may be provided as a deformation (in particular a recess) of the bypass duct wall or as an otherwise formed projection.
- the separator (circle) may be conical or pyramidal. The use of such a separator allows not only to influence the oscillation frequency, but also to vary the so-called oscillation angle.
- the oscillation angle is the angle swept by the oscillating fluid jet (between its two maximum deflections).
- a separator may be provided for each of the bypass ducts or only for a part of the bypass ducts.
- an outlet channel may be provided immediately upstream of the outlet opening.
- the outlet channel may have a cross-sectional shape which is constant over the entire length of the outlet channel and which corresponds to the shape of the cross-sectional area of the outlet aperture (square, rectangular, polygonal, round, etc.).
- the shape of the cross-sectional area of the exhaust passage may change over the length of the exhaust passage.
- the size of the cross-sectional area of the outlet opening can remain constant (this is also the size of the outlet opening) or change.
- the size of the cross-sectional area of the outlet channel may decrease in the fluid flow direction from the inlet opening to the outlet opening.
- the shape and / or size of the cross-sectional area of the main flow channel may change from the inlet opening to the outlet opening.
- the shape of the cross-sectional area (the outlet channel or the main flow channel) may change from rectangular to round (in the fluid flow direction from the inlet opening to the outlet opening).
- the fluid jet can already be pre-bundled in the fluidic component, so that the compactness of the exiting fluid jet can be increased.
- the size of the cross-sectional area of the outlet channel may change, in particular decrease in the fluid flow direction from the inlet opening to the outlet opening.
- the parameters of the fluidic component are variously adjustable. Preferably, these parameters are chosen so that the pressure, which is applied to the fluid flow via the inlet opening into the fluidic component, is reduced substantially at the outlet opening. In this case, a slight pressure reduction occurring at the outlet opening can already take place in the fluidic component (upstream of the outlet opening).
- the flow divider may have different shapes, but all have in common that they widen in the plane in which the exiting fluid jet oscillates and transversely to the longitudinal axis of the fluidic component downstream.
- the flow divider may be located in the outlet duct (if present).
- the flow divider can extend deeper into the fluidic component, for example into the main flow channel.
- the flow divider can be arranged so symmetrically (with respect to an axis extending parallel to the component length) that the outlet openings are identical in shape and size.
- the fluidic component comprises a fluid flow guide, which is arranged downstream of the outlet opening.
- the fluid flow guide is substantially tubular (for example, with a constant large cross-sectional area and constant cross-sectional area shape) and movable by the direction of its fluid flow changing.
- the cross-sectional area of the fluid flow guide may correspond to the cross-sectional area of the outlet opening.
- the movement of the fluid flow guide does not affect the direction of the exiting fluid flow.
- the fluid flow guide merely represents a means (passive component) for additional bundling of the oscillating emergent fluid jet.
- the fluid flow bundled in this way only fills or bursts further downstream than a fluid flow which emerges from a fluidic component without fluid flow guide. In particular, in cleaning technology, this property may be desired.
- the cross-sectional area of the outlet opening of the fluid flow guide can be realized differently.
- the outlet opening of the fluid flow guide is the opening from which the fluid flow exits the fluid flow guide (and thus from the fluidic component).
- shapes for the cross-sectional area of the outlet opening of the fluid flow guide described in connection with the outlet opening of the fluidic component without fluid flow guidance are possible.
- the shape of the cross-sectional area of the fluid flow guide may vary over the length of the fluid flow guide.
- a rectangular cross-sectional area may be provided in the region of the bearing (that is to say at the inlet of the fluid flow guide), which merges downstream into a round cross-sectional area.
- the fluidic component has an outlet extension, which adjoins the outlet opening downstream of the outlet opening.
- the exhaust extension joins downstream of the exhaust port directly (directly) to the exhaust port.
- the outlet extension may be formed, for example, funnel-shaped.
- the outlet extension may have a cross-sectional area (perpendicular to the fluid flow direction). whose size increases downstream of the outlet opening. In this case, the outlet opening can form the point with the smallest cross-sectional area between the flow chamber and the outlet extension.
- the Auslasser shimmer réelle can serve to bundle a fluid jet, which undergoes a high pressure reduction at the outlet opening and thus bursts at the outlet opening. The outlet extension can thus (at least partially) counteract the bursting of the fluid jet. By bundling the fluid jet, an increase in the removal or cleaning performance of the fluidic component can be achieved.
- the outlet extension may have a width that increases (steadily) from the outlet opening downstream.
- the width is that extent of the outlet extension which lies in the plane in which the exiting fluid flow oscillates.
- the depth of the outlet extension can be constant.
- the depth of the outlet extension is that extent of the outlet extension that is directed substantially perpendicular to the plane in which the exiting fluid flow oscillates.
- the depth of the outlet extension can increase or decrease downstream (as compared to the component depth present at the outlet opening).
- the outlet extension may be bounded by a wall including an angle in the plane in which the exiting fluid jet oscillates within an oscillation angle, the angle of the outlet extension being from 0 ° to 15 °, preferably from 0 ° to 10 °, is greater than the oscillation angle.
- the Auslasserweittation does not affect the size of the oscillation angle, but only the bursting of the exiting fluid jet. This angular size is useful, for example, for fluidic components that produce a uniform distribution of the fluid on the surface to be sprayed without outlet expansion.
- the invention further relates to an injection system and a cleaning device, each comprising the fluidic component according to the invention.
- the injection system is for injecting a fuel into an internal combustion engine, such as an internal combustion engine or a gas turbine, which is used for example in motor vehicles.
- the cleaning device is in particular a dishwasher, a washing machine, an industrial cleaning system or a high-pressure cleaner.

- the longitudinal axis A forms an axis of symmetry of the fluidic component 1.
- the longitudinal axis A lies in two mutually perpendicular symmetry planes S1 and S2, with respect to which the fluidic component 1 is mirror-symmetrical.
- the fluidic component 1 can not be constructed symmetrically (mirror).
- the bypass ducts 104a, 104b again change direction at the end of the second section, so that they are respectively directed substantially in the direction of the longitudinal axis A (third section).
- the direction of the bypass ducts 104a, 104b changes at the transition from the second to the third section by an angle of about 120 °.
- angles other than the one mentioned here can also be selected.
- the bypass ducts 104a, 104b are a means for influencing the direction of the fluid flow 2, which flows through the flow chamber 10.
- the bypass ducts 104a, 104b respectively have an inlet 104a1, 104b1, which is essentially formed by the end of the bypass ducts 104a, 104b facing the outlet opening 102, and in each case an outlet 104a2, 104b2 which essentially faces through the inlet opening 101 End of the bypass channels 104a, 104b is formed.
- the secondary streams 23a, 23b Figure 4
- the remaining part of the fluid flow 2 exits the fluidic component 1 via the outlet opening 102 (FIG. 4).
- the secondary streams 23a, 23b emerge at the exits 104a2, 104b2 from the bypass ducts 104a, 104b, where they can exert a lateral (transversely to the longitudinal axis A) impulse on the fluid stream 2 entering through the inlet opening 101.
- the direction of the fluid flow 2 is influenced in such a way that the main flow 24 emerging at the outlet opening 102 spatially oscillates, in a plane in which the main flow passage 103 and the bypass flow passages 104a, 104b are arranged.

- the component length I of the fluidic component 1 from FIG. 4 is 18 mm and the component width b is 20 mm (FIG. D)).

- the angle which the exiting main flow 24 passes over between these two maxima is the oscillation angle ⁇ (FIG. 7).
- Figure b) shows the flow lines for a position of the exiting main flow 24, which lies approximately in the middle between the two maxima from the figures a) and c). The following describes the flows within the fluidic component 1 during an oscillation cycle.
- the main stream 24 exits the outlet port 102 at a time varying angle with respect to the longitudinal axis A.
- the main flow 24 is applied to the side wall of the one block 11 a and the recirculation area 25b has its maximum size.
- the main flow 24 emerges from the outlet opening 102 with approximately the greatest possible deflection.
- the main flow 103 does not apply, significantly larger than the part of the fluid flow 2, which flows into the bypass duct 104 a, which adjoins the block 11 a, on the side wall of which the main current 103 applies.
- the secondary flow 23b is significantly greater than the secondary flow 23a, which is almost negligible.
- the deflection of the fluid flow 2 into the bypass ducts 104a, 104b can be influenced and controlled by separators.
- the secondary streams 23a, 23b (in particular the secondary stream 23b) flow through the secondary flow channels 104a or 104b to their respective outlets 104a2, 104b2 and thus give a pulse to the fluid stream 2 entering at the inlet opening 101. Since the sub-stream 23b is larger than the sub-stream 23a, the pulse component resulting from the sub-stream 23b outweighs.
- the main stream 24 is thus pressed by the pulse (the secondary stream 23 b) to the side wall of the block 11 a.
- the recirculation area 25b moves toward the entrance 104b1 of the bypass passage 104b, thereby disturbing the supply of fluid into the bypass passage 104b.

- the recirculation area 25b decreases, while a further (growing) recirculation area 25a is formed between the main flow 24 and the side wall of the block 11a.
- the supply of fluid in the bypass duct 104a increases.
- the pulse component resulting from the bypass 23a increases with it.
- the recirculation area 25a will migrate and block the entrance 104a1 of the bypass duct 104a, so that the supply of fluid here again decreases.
- the secondary flow 23b will deliver the dominant momentum component so that the main flow 24 is again forced away from the side wall of the block 11b.

- Figures a) to c) show that the main flow 24 at the outlet opening 102 with a Escape speed, which is always higher than the speed at which the fluid flow
- FIG. 6 shows the corresponding pressure field of the fluid flow 2 for the snapshot from FIG. 4 b) (FIG. 5 b)).
- the pressure is coded logarithmically with a color code. The scale shown ranges from 1 bar (white) to 60 bar (black). Upstream of the inlet opening 101, the pressure of the fluid is 56 bar. The ambient pressure is 1 bar (white).
- FIG. 6 clearly shows that the pressure of the fluid in the entire fluidic component 1 is high and corresponds substantially to the pressure before entry into the fluidic component 1 through the inlet opening 101. Only at the outlet opening 102, the pressure of the fluid drops abruptly to the ambient pressure. In connection with FIG. 5b) it can be seen that the fluid is accelerated at this point of the pressure drop.

- the fluidic components from FIGS. 8 and 9 correspond to the fluidic component 1 from the figures 1 to 3 and differ from the latter only by the cross-sectional shapes of the main flow channel 103 and the bypass channels 104a, 104b. While these are each rectangular in the embodiment of Figure 3, they are each oval in the embodiment of Figure 8 and in the embodiment of Figure 9 are each rectangular with rounded corners.
- the flow divider 108 each has the shape of a triangular wedge.
- the wedge has a depth that corresponds to the component depth t. (The component depth t is constant over the entire fluidic component 1).
- the flow divider 108 divides the outlet duct 107 into two subchannels with two outlet openings 102 and the fluid flow 2 into two substreams which emerge from the fluidic component 1.
- the two substorms pulsed out of the two outlet openings 102.
- the two outlet openings 102 each have a smaller width bsx than the inlet opening 101.
- FIG. 12 shows the fluidic component 1 from FIG. 1, which additionally has a fluid flow guide 109.
- the fluid flow guide 109 is a tubular extension disposed at the outlet port 102 and extending downstream from the outlet port 102.
- the fluid flow guide 109 serves to bundle the exiting fluid flow, without acting on the oscillation mechanism.

- the fluidic component 1 additionally has a flow guide body 110, which is connected to the fluid flow guide 109 by means of a holder 111.
- the flow guide body 110 serves to support the deflection of the fluid flow emerging from the outlet opening 102 and thus also the movement of the fluid flow guide 109 by utilizing the fluid dynamics in the flow chamber 10.
- the holder 111 is designed such that it does not interfere with the oscillation mechanism of the exiting fluid flow. In particular, the holder has a small cross section and thus a negligible flow resistance.
- the holder 111 establishes a rigid connection between the flow guide body 110 and the fluid flow guide 109.
- the flow guide body 110 is therefore not movable relative to the fluid flow guide 109, but only together with the fluid flow guide 109.
- the shape of the flow guide body 110 may be different.
- the flow guide body 110 may be streamlined.
- the rectangular shape of the flow guide body 110 shown in FIG. 13 is only a schematic representation.
- the flow guide body 110 described with reference to FIG. 13 is not restricted to the fluidic component 1 shown in FIG. 13, but can also be used in other fluidic components 1 with a fluid flow guide 109.
- the fluid flow guide 109 can be used in other fluidic components except those of Figures 12 and 13.
- the bypass duct 104a has a greater width at its entrance 104a1 and at its exit 104a2 than in a section between entrance 104a1 and exit 104a2.

- the width of the bypass ducts 104a, 104b changes differently over their length. This is achieved in that the two blocks 11 a, 11 b formed differently in shape and size and are not aligned symmetrically with respect to the mirror plane S2. As a result, the shape of the main flow channel 103 is not symmetrical to the mirror plane S2. However, both bypass channels 104a, 104b can behave the same with respect to their width change.
- the manufacturing process (casting, sintering) of the fluidic component 1 can be simplified, since foreign substances can be easily removed from the fluidic component during production.
- the finished fluidic component is easier to clean, which plays a role, for example, when the fluidic component is used with a foreign substance-laden (particle-laden) fluid.
- the cross section increases from the output of the bypass duct towards the inlet of the bypass channel, the fluidic component flushes automatically during operation.

- the inlet pressure which is, for example, higher than 14 bar (compared to the ambient pressure), but can also be over 1000 bar, and preferably between 20 bar and 500 bar, degraded substantially only at the outlet opening 102. Due to the high pressure reduction directly at the outlet opening 102, the exiting fluid jet (in all directions) may tend to burst. This bursting can be counteracted (at least in part) by the outlet extension 12. Through the outlet extension 12, a bundling of the exiting fluid jet (perpendicular to the planes of symmetry S1 and S2) can be achieved.

- the angle ⁇ can also be greater than the corresponding oscillation angle ⁇ may be formed.
- a fluidic component 1 which produces a uniform distribution of the fluid on the surface to be sprayed (also known as histogram) without outlet extension 12
- a fluidic component 1 without outlet extension 12 generates an uneven distribution of the fluid on the surface to be sprayed (for example more fluid in the middle than in the edge regions) or in the case that a smaller spray angle or oscillation angle ⁇ is desired
- An outlet extension 12 may be provided whose angle ⁇ corresponds to the desired reduced oscillation angle ⁇ .
- a smaller oscillation angle ⁇ is generated and, on the other hand, a more uniform distribution of the fluid on the surface to be sprayed or in the histogram is thereby produced.
