Abstract
Description
Die Erfindung betrifft einen Durchflussmengenbegrenzer mit einem Durchflusskörper, wobei der Durchflusskörper von zumindest einem von einem Fluidum durchströmbaren Kanal mit einer Einlassöffnung und einer Auslassöffnung durchsetzt ist und zumindest ein Gaskanal mit einer Gasansaugöffnung und einer Gasaustrittsöffnung für ein mit dem aus dem Kanal austretendem Fluidum zu vermischendes Gas vorgesehen ist und an die Einlassöffnung ein Einlasstrichter anschließt.The invention relates to a flow rate limiter with a flow body, wherein the flow body is penetrated by at least one of a fluid flow-through channel with an inlet opening and an outlet opening and at least one gas channel with a gas suction and a gas outlet opening for a to be mixed with the leaving the channel fluid to be mixed gas is provided and connects to the inlet opening an inlet funnel.
Weiters betrifft die Erfindung eine Aufnahme zur Durchflussmengenbegrenzung mit einer Eintrittsöffnung und einer Austrittsöffnung für zumindest ein Fluidum, wobei die Eintrittsöffnung einen größeren Querschnitt als die Austrittsöffnung aufweist.Furthermore, the invention relates to a receptacle for limiting the flow rate with an inlet opening and an outlet opening for at least one fluid, wherein the inlet opening has a larger cross-section than the outlet opening.
Zudem betrifft die Erfindung ein Verfahren zum Vermischen von zumindest einem Fluidum mit zumindest einem Gas, unter anderem von Wasser und Luft.In addition, the invention relates to a method for mixing at least one fluid with at least one gas, including water and air.
Durchflussmengenbegrenzer der eingangs erwähnten Art sind beispielsweise aus der
Die
Weiters enthält der in der
Nachteilig an den bekannten Durchflussmengenbegrenzern sind eine geringe Vermischungsrate von Fluidum und Gas sowie deren komplizierter mechanischer Aufbau.A disadvantage of the known flow restrictors are a low mixing rate of fluid and gas and their complicated mechanical structure.
Es ist daher Aufgabe der Erfindung, einen Durchflussmengenbegrenzer zu schaffen, um eine deutliche Durchflussmengenreduktion bei hoher Gasaufnahme zu erzielen.It is therefore an object of the invention to provide a flow restrictor to achieve a significant flow reduction with high gas absorption.
Diese Aufgabe wird durch einen Durchflussmengenbegrenzer der eingangs erwähnten Art erfindungsgemäß dadurch gelöst, dass an der Einlassöffnung ein Einlasstrichter anschließt. Der Einlasstrichter bewirkt hohe Durchflussgeschwindigkeiten des Fluidums im Kanal, zudem wird das Fluidum in Rotation versetzt. Diese hohen Durchflussgeschwindigkeiten bewirken im Bereich der Austrittsöffnung des Kanals einen Unterdruck, sodass hohe Gasmengen über den Gaskanal angesaugt und vom verwirbelten Fluidum aufgenommen werden. Die Durchflussmenge an Duschwasser beispielsweise kann dadurch von üblicherweise 15 bis 19 L/min auf 3 bis 5 L/ min reduziert werden, ohne dass der Duschkomfort vermindert wird, weil aufgrund der Luftansaugung über den Gasansaugöffnung das Volumen des Wasserstrahls vergrößert wird. Dies erlaubt eine deutliche Kostenreduzierung beim Wasserverbrauch sowie bei den Energiekosten zur Warmwasseraufbereitung.This object is achieved by a flow rate limiter of the type mentioned in the present invention, that connects to the inlet opening an inlet funnel. The inlet funnel causes high flow rates of the fluid in the channel, in addition, the fluid is set in rotation. These high flow rates cause a negative pressure in the region of the outlet opening of the channel, so that high amounts of gas are sucked in via the gas channel and absorbed by the swirling fluid. The flow rate of shower water, for example, can thereby be reduced from usually 15 to 19 L / min to 3 to 5 L / min, without the showering comfort is reduced, because due to the air suction through the gas suction opening, the volume of the water jet is increased. This allows a significant cost reduction in water consumption and energy costs for hot water treatment.
In einer bevorzugten Ausführung entspricht die Krümmung des Einlasstrichters einer Kurve F(x) = C * 1/x. Dies hat eine erhöhte Beschleunigung des Fluidums im Kanal zur Folge. Diese Kurvenform entspricht in der Natur bekannten Phänomenen, bei welchen Kräfte optimal wirken können (z.B.: Tornados, Corioliskraft etc.).In a preferred embodiment, the curvature of the inlet funnel corresponds to a curve F (x) = C * 1 / x. This results in an increased acceleration of the fluid in the channel. This waveform corresponds to phenomena known in nature in which forces can act optimally (for example: tornadoes, Coriolis force, etc.).
Vermehrte Gasaufnahme und damit Volumsvergrößerung des Fluidums wird erzielt, wenn der zumindest eine Kanal für das Fluidum und die zumindest eine Gasaustrittsöffnung in einer Ebene beispielsweise in eine Mischkammer münden.Increased gas absorption and thus volume increase of the fluid is achieved when the at least one channel for the fluid and the at least one gas outlet opening in a plane, for example, open into a mixing chamber.
Die Herstellung eines erfindungsgemäßen Durchflussmengenbegrenzers wird erheblich erleichtert, wenn der zumindest eine Kanal im Bereich anschließend an den Einlasstrichter kreiszylindrisch ausgeführt und axial im Durchflusskörper angeordnet ist.The production of a flow rate limiter according to the invention is considerably facilitated if the at least one channel in the area adjacent to the inlet funnel is designed as a circular cylinder and arranged axially in the flow body.
Bei handelsüblichen Durchflussmengenbegrenzern kann aufgrund von Druckunterschieden in der Zuleitung des Fluidums die Ansaugung des Gases unterbrochen und Fluidum in den Gaskanal gelangen. Dieser Effekt kann verhindert werden, wenn vorteilhafterweise im Gaskanal ein Rückschlagventil angeordnet ist.In commercially available flow rate limiters, due to pressure differences in the supply line of the fluid, the suction of the gas can be interrupted and fluid can enter the gas channel. This effect can be prevented if advantageously in the gas passage a check valve is arranged.
In einer weiteren Ausführung des Durchflussmengenbegrenzers weist dieser zumindest eine Ausnehmung zum Aufnehmen von magnetischem, mineralischem oder organischem Material auf. Magneten beeinflussen laut unterschiedlicher Studien die Ablagerung von Kalk in Wasser führenden Leitungen und Armaturen.In a further embodiment of the flow rate limiter this has at least one recess for receiving magnetic, mineral or organic material on. According to various studies, magnets influence the deposition of lime in water pipes and fittings.
Weiters wird die Aufgabe dadurch gelöst, dass ein Durchflussmengenbegrenzer zwischen Eintrittsöffnung und Austrittsöffnung einer Aufnahme angeordnet. Diese Aufnahme kann mit wenigen Handgriffen an Schläuche, Rohren, Armaturen und anderen Elementen, die für den Transport von Fluida vorgesehen sind, montiert werden.Furthermore, the object is achieved in that arranged a flow restrictor between the inlet opening and outlet opening of a recording. This mount can be mounted in a few easy steps to hoses, pipes, fittings and other elements intended for the transport of fluids.
In der oben genannten Aufnahme steht die Gasansaugöffnung des Durchflussmengenbegrenzers im montierten Zustand mit einem Gasansaugkanal der Aufnahme in fluchtender Verbindung, sodass eine ungehinderte Gasansaugung gewährleistet ist.In the above recording, the gas suction port of the flow restrictor is in the mounted state with a gas intake passage of the receptacle in alignment, so that an unhindered gas suction is ensured.
In einer weiteren Variante der Erfindung münden der zumindest eine Kanal für das Fluidum und die zumindest eine Gasaustrittsöffnung in eine in Durchflussrichtung durchlässige Mischkammer. Dies hat den Vorteil, dass die Vermischung des Fluidums mit dem Gas nach der Beschleunigung des Fluidums im Kanal erfolgt.In a further variant of the invention, the at least one channel for the fluid and the at least one gas outlet opening open into a mixing chamber which is permeable in the direction of flow. This has the advantage that the mixing of the fluid with the gas takes place after the acceleration of the fluid in the channel.
Weist die Mischkammer einen kegelstumpfförmigen Querschnitt auf, so erfolgt eine maximale Gasaufnahme des Fluidums.If the mixing chamber has a frustoconical cross-section, maximum gas absorption of the fluid takes place.
In einer anderen Ausführung der Erfindung weist die Mischkammer abgerundete Schultern auf, deren Krümmung einer Kurve F(x) = C * 1/x entspricht. Dies hat den Vorteil, dass die Verwirbelung des Fluidums nochmals verstärkt und die Gasanreicherung erhöht wird.In another embodiment of the invention, the mixing chamber has rounded shoulders whose curvature corresponds to a curve F (x) = C * 1 / x. This has the advantage that the turbulence of the fluid again reinforced and the gas enrichment is increased.
Im montierten Zustand kann der in die Aufnahme eingesetzte Durchflussmengenbegrenzer aufgrund der hohen Fließgeschwindigkeit des Fluidums in Schwingung geraten. Dies führt zu unerwünschter Geräuschentwicklung (Pfeifen, Dröhnen, etc.). Um dies zu vermeiden und um einen eventuell notwendigen Druckausgleich zu erlauben, weist der Durchflussmengenbegrenzer an der äußeren Mantelfläche zumindest eine Einnutung auf.When assembled, the flow restrictor used in the receptacle may vibrate due to the high flow rate of the fluid. This leads to unwanted noise (whistling, roaring, etc.). In order to avoid this and to allow a possibly necessary pressure equalization, the flow rate limiter has at least one groove on the outer jacket surface.
Ebenso ist eine derartige Aufnahme realisierbar, bei welcher die Aufnahme an der inneren Mantelfläche zumindest eine Einnutung aufweist.Likewise, such a receptacle can be realized, in which the receptacle on the inner circumferential surface has at least one groove.
Krankenhäuser und Hotels haben naturgemäß einen hohen Wasserverbrauch, daher ist der Einsatz von Aufnahmen, die eine Reduktion des Wasserverbrauchs ermöglichen, aus ökologischen und ökonomischen Gründen erstrebenswert. Da vor allem in Krankenhäusern saubere und leicht zu reinigende Oberflächen gefordert sind, ist in einer weiteren bevorzugten Ausführung der Aufnahme die äußere Oberfläche der Aufnahme glatt ausgeführt.Hospitals and hotels naturally have a high water consumption, so the use of photographs that allow a reduction in water consumption is desirable for ecological and economic reasons. Since above all in hospitals clean and easy-to-clean surfaces are required, in a further preferred embodiment of the recording, the outer surface of the recording made smooth.
In einer weiteren Ausführung der Erfindung ist in der Aufnahme zumindest ein Mittel zur Regelung der Durchflussmenge vorgesehen. Dieses Mittel kann zusätzlich von außen beispielsweise durch einen Inbusschlüssel betätigt werden.In a further embodiment of the invention, at least one means for regulating the flow rate is provided in the receptacle. This agent can be additionally actuated from the outside, for example by an Allen key.
Des Weiteren weist in einer weiteren bevorzugten Variante der Erfindung das Gehäuse im Bereich der Austrittsöffnung oder im Bereich des Durchflussmengenbegrenzers zumindest eine Ausnehmung zum Aufnehmen von magnetischem, mineralischem oder organischem Material auf. Das in der Ausnehmung platzierte Material kann beispielsweise mineralisches Material sein, das zu therapeutischen Zwecken eingesetzt wird. So werden bevorzugt Halbedelsteine zur Energetisierung von Trinkwasser eingesetzt.Furthermore, in a further preferred variant of the invention, the housing has at least one recess for receiving magnetic, mineral or organic material in the region of the outlet opening or in the region of the flow rate limiter. The material placed in the recess may be, for example, mineral material used for therapeutic purposes. For example, semi-precious stones are used to energize drinking water.
Die Verwendung des Durchflussmengenbegrenzers zur Vermischung von Wasser als Fluidum und Luft als Gas ist eine der bevorzugten Anwendungen der Erfindung, jedoch ist die Erfindung ebenso für das Verwirbeln und Mischen von unterschiedlichsten Flüssigkeiten oder Gasen mit einem angesaugten Gas einsetzbar.The use of the flow limiter to mix water as fluid and air as gas is one of the preferred applications of the invention, however, the invention is equally applicable to the fluidization and mixing of a wide variety of liquids or gases with a suctioned gas.
Die Aufnahme ist einsetzbar in einem Verfahren zum Vermischen von zumindest einem Fluidum mit zumindest einem Gas, wobei die Durchflussmenge des zumindest einen Fluidums verringert und dessen Durchflussgeschwindigkeit erhöht wird, sowie das Fluidum verwirbelt und hierauf mit dem zumindest einen Gas vermischt wird. Durch die Verwirbelung des Fluidums wird eine maximale Aufnahme an Gasvolumen ermöglicht.The receptacle can be used in a method for mixing at least one fluid with at least one gas, wherein the flow rate of the at least one fluid is reduced and its flow rate is increased, and the fluid is fluidized and then mixed with the at least one gas. The turbulence of the fluid allows a maximum absorption of gas volume.
Dieses Verfahren, werden Wasser als Fluidum und Luft als Gas verwendet, ist geeignet, um den Sauerstoffgehalt des Wassers, das unter Umständen lange Zeit in beispielsweise Rohren oder Tanks unter Druck gelagert wurde, zu erhöhen und damit als Trinkwasser aufzuwerten.This method, when water is used as a fluid and air as a gas, is suitable for increasing the oxygen content of the water, which may have been stored for a long time in, for example, pipes or tanks under pressure, and thus upgrading it as drinking water.

Die in Fig.1 dargestellte Aufnahme AUF zur Durchflussmengenbegrenzung wird beispielsweise in Duschen zur Reduktion des Wasserverbrauchs eingesetzt.The intake AUF shown in Figure 1 for flow rate limitation is used for example in showers to reduce water consumption.
Kernstück der Aufnahme AUF ist der in Fig. 2 dargestellte Durchflussmengenbegrenzer DUR. Er weist in einem Durchflusskörper DUK eine Einlassöffnung EIN auf, die einen Einlasstrichter ELT aufweist, durch welche das Fluidum, in diesem Fall Wasser, in den Kanal KAN eintreten kann. Die Krümmung des Einlasstrichters ELT entspricht einer Kurve F(x) = C*1/× in einer Ebene, die durch die Längsmittelgerade y verläuft. Durch diese spezielle Form wird das Wasser während des Durchtrittes durch den Kanal KAN in Rotation versetzt und im Kanal KAN beschleunigt. Aufgrund der hohen Durchtrittsgeschwindigkeit des Wassers entsteht im Raum unterhalb der Austrittsöffnung AUS ein Unterdruck, der eine Gasansaugung, beispielsweise Luft, im die Gaskanal GKA bewirkt. Die angesaugte Luft vermischt sich mit dem beschleunigten, verwirbelten Wasser. Durch das Einbringen der Luft in das Wasser wird das Volumen des Wasserstrahls vergrößert und der Duschkomfort bleibt erhalten, während der Wasserverbrauch sich von beispielsweise 15 bis 19 L/min auf 3 bis 5 L/min reduziert.The heart of the recording AUF is the flow rate limiter DUR shown in FIG. It has an inlet opening IN in a flow body DUK, which has an inlet funnel ELT through which the fluid, in this case water, can enter the channel KAN. The curvature of the inlet funnel ELT corresponds to a curve F (x) = C * 1 / x in a plane passing through the longitudinal middle straight y. Due to this special shape, the water is set in rotation during the passage through the channel KAN and accelerated in the channel KAN. Due to the high passage speed of the water created in the space below the outlet opening OFF a negative pressure, which causes a gas suction, such as air in the gas duct GKA. The sucked air mixes with the accelerated, swirling water. By introducing the air into the water, the volume of the water jet is increased and the showering comfort is maintained, while the water consumption is reduced from, for example, 15 to 19 L / min to 3 to 5 L / min.
Selbstverständlich kann der in Fig. 2 dargestellte Durchflussmengenbegrenzer DUR ohne die in Fig. 3 gezeigte Aufnahme AUF zum Einsatz kommen. Beispielsweise können an die beiden längsseitigen, der Einlassöffnung EIN und der Austrittsöffnung AUS zugeordneten Enden des Durchflussmengenbegrenzer DUR je ein Schlauchstück mittels Schlauchbinder befestigt werden.Of course, the flow rate limiter DUR shown in FIG. 2 can be used without the receptacle UP shown in FIG. 3. For example, one piece of hose per hose piece can be attached to each of the two longitudinal ends of the flow rate limiter DUR associated with the inlet opening A and the outlet opening DUR.
Die Aufnahme AUF, wie in Fig. 3 gezeigt, besteht aus einem Gehäuse GEH, das im Bereich der Einlassöffnung INL und der Auslassöffnung OUT jeweils ein Gewinde aufweist (in den Figuren nicht dargestellt), die beispielsweise zur Montage der Aufnahme AUF in einen Duschschlauch dienen. Die Oberfläche OBE des Gehäuses GEH ist glatt ausgeführt, dies erlaubt eine einfache Reinigung der Aufnahme AUF, eine Eigenschaft, die auch in Hinblick auf Keimfreiheit, in Krankenhäusern zum Beispiel, wünschenswert ist.The receptacle UP, as shown in Fig. 3, consists of a housing GEH, each having a thread in the region of the inlet port INL and the outlet port OUT (not shown in the figures), for example, for mounting the receptacle UP in a Shower hose serve. The surface OBE of the housing GEH is made smooth, this allows easy cleaning of the receptacle AUF, a property that is also desirable in terms of sterility, in hospitals, for example.
Zusätzlich weist das Gehäuse GEH einen Gasansaugkanal GAS auf, der, bei eingesetztem Durchflussmengenbegrenzer DUR, fluchtend mit dessen Gasansaugöffnung GAF in Verbindung steht (Fig.1). Der Gaskanal GKA ist mit einem Rückschlagventil RUC gesichert, somit kann bei Druckschwankungen oder ähnlichem kein Wasser bei der Gasansaugöffnung GAF austreten.In addition, the housing GEH has a gas intake duct GAS, which, with the flow restrictor DUR inserted, is in alignment with its gas intake opening GAF (FIG. 1). The gas channel GKA is secured with a check valve RUC, thus, in the case of pressure fluctuations or the like, no water can escape at the gas suction opening GAF.
Die Austrittsöffnung AUS des Durchflussmengenbegrenzers DUR befindet sich mit der Austrittsöffnung GUF des Gaskanals GKA in einer Ebene und mündet in eine Mischkammer MIS. Diese Mischkammer MIS weist einen kegelstumpfförmigen Querschnitt auf, der eine optimale Vermischung des Wassers mit der Luft gewährleistet.The outlet opening OUT of the flow restrictor DUR is in a plane with the outlet opening GUF of the gas channel GKA and opens into a mixing chamber MIS. This mixing chamber MIS has a frusto-conical cross section, which ensures optimum mixing of the water with the air.
Der Durchflussmengenbegrenzer DUR ist in dieser Ausführungsform der Erfindung ohne zusätzliche Befestigungsmittel in das Gehäuse GEH der Aufnahme AUF eingesetzt. Dies hat den Vorteil, dass der Durchflussmengenbegrenzer DUR mit wenigen Handgriffen aus der Aufnahme AUF entnommen werden kann, zum Beispiel zu Reinigungszwecken, oder es kann ein mit beispielsweise unterschiedlichem Kanaldurchmesser ausgestatteten Durchflussmengenbegrenzer ersatzweise eingesetzt werden. Somit kann eine Aufnahme AUF mit unterschiedlichen Durchflussmengenbegrenzern bestückt werden.The flow restrictor DUR is used in this embodiment of the invention without additional fastening means in the housing GEH recording UP. This has the advantage that the flow restrictor DUR can be removed in a few steps from the receptacle OP, for example, for cleaning purposes, or it can be used as a substitute equipped with, for example, different channel diameter flow rate limiter. Thus, a recording AUF can be equipped with different flow rate limiters.
Da der Durchflussmengenbegrenzer DUR in der hier beschriebenen Ausführungsform in die Aufnahme AUF lediglich eingesetzt und nicht zusätzlich fixiert ist, kann es aufgrund der hohen Durchtrittsgeschwindigkeiten des Wassers zum Vibrieren des Durchflussmengenbegrenzer DUR in der Aufnahme AUF kommen. Dieses Vibrieren ist mit unerwünschter Geräuschentwicklung verbunden. Um derartige Effekte zu vermeiden, weist der äußere Mantel AMA des Durchflusskörpers DUK eine Einnutung NUT auf.Since the flow restrictor DUR in the embodiment described here in the receptacle ON only used and not additionally fixed, it may come to vibrate the flow restrictor DUR in the recording OPEN due to the high passage speeds of the water. This vibration is associated with undesirable noise. In order to avoid such effects, the outer jacket AMA of the flow body DUK has a slot NUT.
In einer weiteren Ausführung der Erfindung (nicht dargestellt) findet sich die Einnutung an der Mantelinnenseite IMA der Aufnahme AUF.In a further embodiment of the invention (not shown) is the slot on the inside of the shell IMA recording on.
In Fig. 4 ist eine weitere Variante der Erfindung dargestellt. Die Mischkammer MIS weist ebenfalls gekrümmte Schultern SUL auf, deren Verlauf einer Kurve F(x) = C*1/x entspricht. Zusätzlich sind Mittel MIT dargestellt, die den Zulauf bzw. Ablauf des Wassers regulieren. Dabei wird beispielsweise ein Stift, der über eine vergrößerte Spitze (nicht dargestellt) verfügt, in den Kanal KAN oder in die Auslassöffnung OUT gebracht. Dadurch verringert sich der Durchmesser des Kanals bzw. der Auslassöffnung OUT, und der Durchfluss wird reduziert. Das Positionieren der Stiftspitze kann beispielsweise durch Verdrehen des Stiftes in einem entsprechenden Gewinde erfolgen.4, a further variant of the invention is shown. The mixing chamber MIS also has curved shoulders SUL whose course corresponds to a curve F (x) = C * 1 / x. In addition, means MIT are shown, which regulate the inflow or outflow of the water. In this case, for example, a pin which has an enlarged tip (not shown) is brought into the channel KAN or into the outlet opening OUT. This reduces the diameter of the channel or the outlet opening OUT, and the flow is reduced. The positioning of the pen tip can be done for example by turning the pin in a corresponding thread.
Die eingesetzten Medien sind Wasser als Fluidum und Luft als angesaugtes Gas. Selbstverständlich ist der Einsatz jeglicher Fluida (flüssig oder gasförmig) denkbar.The media used are water as fluid and air as sucked gas. Of course, the use of any fluids (liquid or gaseous) is conceivable.
Die in Fig. 5 dargestellte weitere Ausführung der Erfindung weist im Bereich der Auslassöffnung OUT eine Ausnehmung AUN auf. Diese ist, wie in Fig. 6a gezeigt, ringförmig ausgebildet. Die Ausnehmung AUN dient zur Aufnahme magnetischen Materials. Untersuchungen haben gezeigt, dass magnetische Felder Kalkablagerungen in Wasser führenden Leitungen und Armaturen positiv beeinflussen. Der Einsatz von Magneten kann daher mögliche Kalkablagerungen in dem Durchflussmengenbegrenzer DUR bzw. in der Aufnahme AUF reduzieren.The further embodiment of the invention shown in FIG. 5 has a recess AUN in the region of the outlet opening OUT. This is, as shown in Fig. 6a, annular. The recess AUN serves to accommodate magnetic material. Investigations have shown that magnetic fields have a positive influence on limescale deposits in pipes and fittings carrying water. The use of magnets can therefore reduce possible calcification in the flow restrictor DUR or in the receptacle OP.
Fig. 6b bis 6d zeigen weitere Ausführungsformen der Ausnehmung AUN. Die Ausnehmung AUN kann auch in Form zwei oder mehr Bohrungen ausgeführt sein, die symmetrisch um die Auslassöffnung OUT angeordnet sind.FIGS. 6b to 6d show further embodiments of the recess AUN. The recess AUN can also be designed in the form of two or more bores, which are arranged symmetrically around the outlet opening OUT.
Des Weiteren kann die Position der Ausnehmungen AUN in dem Gehäuse GEH oder auch in dem Durchflussmengenbegrenzer DUR realisiert sein. In der in Fig. 7 dargestellten Ausführungsform befinden sich im Gehäuse zwei Ausnehmungen AUN, die im Bereich des Durchflussmengenbegrenzer DUR angeordnet sind, während in den in Fig. 8 und 9 gezeigten Varianten die Ausnehmungen AUN im Durchflussmengenbegrenzer DUR ausgebildet sind. Die letztere Ausführung hat den Vorteil, dass sie einfach zu fertigen ist.Furthermore, the position of the recesses AUN can be realized in the housing GEH or also in the flow rate limiter DUR. In the embodiment shown in Fig. 7 are located in the housing two recesses AUN, which are arranged in the region of the flow rate limiter DUR, while in the variants shown in FIGS. 8 and 9, the recesses AUN are formed in Durchflußmengenbegrenzer DUR. The latter embodiment has the advantage that it is easy to manufacture.
Es versteht sich, dass die Ausnehmungen auf unterschiedlichste Weise in der Vorrichtung angeordnet sein können. Ebenso sind Kombinationen der oben beschriebenen Ausführungsformen realisierbar. Ebenso kann die Ausnehmung so ausgebildet sein, dass die Aufnahme mehrerer Magnete nebeneinander oder ineinander gesteckt ermöglicht ist.It is understood that the recesses can be arranged in various ways in the device. Likewise, combinations of the embodiments described above can be realized. Likewise, the recess may be formed so that the inclusion of a plurality of magnets next to each other or inserted into each other is possible.
Auch ist die Verwendung der Ausnehmungen nicht auf die Aufnahme von magnetischem Material beschränkt. Ebenso kann die Aufnahme von mineralischem oder organischem Material, wie beispielsweise Halbedelsteinen, Schüssler-Salzen oder Bachblütenessenzen zu therapeutischen Zwecken vorgesehen sein. Kombinationen aus den unterschiedlichen Materialien sind ebenfalls möglich.Also, the use of the recesses is not limited to the inclusion of magnetic material. Likewise, the inclusion of mineral or organic material, such as semi-precious stones, Schuessler salts or Bach flower essences may be provided for therapeutic purposes. Combinations of the different materials are also possible.
