Definitions
- the invention relates to a shower head with a shower head housing, a water inlet and a jet exit disc.
- the jet exit disc makes an eccentric movement without twisting.
- the jet outlet elements which are made of elastic material, move on a cone, with all jet outlet elements remaining parallel to one another ( WO00 / 10720 ).
- the invention is based on the object to provide a shower head, in which even with a large-scale radiation without additional water consumption strong water jets are generated.
- the invention proposes a shower head with the features mentioned in claim 1. Further developments of the invention are the subject of the dependent claims.
- the shower head according to the invention thus contains two separate chambers from which the water can flow out through the jet outlet openings of the jet disc. These chambers are so separated, it is possible to provide one of the two chambers with water, while the other chamber is not supplied with water. So the water can not flow from one chamber to the other.
- the valve means which can open and close the chambers, it is then possible to supply a chamber separately from another chamber with water. When switching then suddenly occur from all the beam outlet openings of a chamber water jets, or be switched off. It is therefore not one jet outlet opening after the other switched on or off, but always a whole group of jet outlet openings.
- the valve device has at least one valve closing body which cooperates with an inlet in at least two, preferably all chambers.
- at least one valve closing body which, however, is then responsible for at least two, but in particular all chambers. This simplifies the construction of the valve device.
- valve device has a plurality of valve closing bodies. Also then it can be provided that at least one valve closing body cooperates with the inlet in all chambers.
- valve closing bodies for at least one chamber, a separate valve closing body is present, which does not interact with the other chambers.
- this chamber has only one inlet.
- a turbine is arranged, which is connected via a gear or directly to the valve closing body.
- the showerhead housing has a particularly circular jet exit disc, wherein the chambers have the base area of a circular sector. In this way it can be ensured that the entire base area of the jet exit disk is available for openings, and that it becomes possible to use a rotating valve closing body.
- the inlets are arranged in the chambers along a circular arc.
- the chambers are bounded on the one hand by the jet exit disc and on the other hand by an intermediate disc.
- the housing can be very easy to assemble, especially when both the jet exit disc on its inside and the washer have the same shape, for example, are formed as flat slices
- at least one valve closing body is formed as a flat washer resting on the side of the intermediate disk facing the water inlet. It can be moved on this disc and interact directly with an inlet opening for the chamber in the washer.
- the closing disc has an edge toothing, which meshes with a ring gear connected to the turbine.
- the closing disc has a peripheral toothing, which is arranged with a arranged on the inside of the shower head housing along the entire circumference toothing.
- edge toothing of the closing disc is engaged both with the turbine and with the housing-side toothed ring.
- the sliding and rotating closing disc does not have its own bearing.
- the in FIG. 1 illustrated shower head includes a flat-cylindrical housing having on its side facing away from the user a water inlet 1 for connection to a water pipe, a hose or the like.
- the housing On the opposite side, the housing is bounded by a jet exit disc 2, which in the illustrated Example is formed as a flat circular disc.
- a jet exit disc 2 In the jet exit disc a plurality of jet outlet openings 3 is arranged, from which water flows out during operation of the shower.
- a jacket four is formed, which lies in the example shown on a cylinder jacket surface.
- FIG. 2 shows on an enlarged scale a side view of such a shower head.
- the water inlet 1 widens immediately behind its junction, top in FIG. 1 so that it has a larger inner diameter when entering the showerhead housing.
- FIG. 3 shows a section through the showerhead housing in a plane parallel to the view of FIG. 2 ,
- the jet exit disc 2 is integral with the jacket 4 of the showerhead housing. This could also be solved differently.
- On the back of the water inlet 1 facing the shower is closed by a cover 5.
- an intermediate disc 6 is arranged, which is formed as a flat disc and thus parallel to the inside of the jet exit disc 2 extends.
- This washer 6 has a raised edge 7, which rests with its outside on the inside of the shell 4.
- each chamber 8 is formed between the jet exit disc 2 and the washer 6 individual chambers 8 are formed. They extend from a point 9 adjacent to the center of the cross section of the housing to the inside of the outer wall 4.
- the individual chambers are separated by ribs 10, on which rests the washer 6.
- FIG. 3 on the right the section is laid through a chamber 8, while to the left of the center line, the section passes through a rib 10. From each chamber 8, of which FIG. 3 only one shows lead several jet outlets 3 into the open.
- the intermediate wall 6 has for each chamber 8 a single inlet opening 11, which in section the FIG. 3 can also be seen.
- the washer 6 While the washer 6 is formed flat on its side facing the jet exit disc 2, so that it rests on the surface of the ribs 10 completely and thus sealingly, it contains on its side facing the water inlet 1 in the middle of a journal 12.
- the hub 13 of a turbine On the journal 12, the hub 13 of a turbine is supported.
- the hub 13 is set between the washer 6 and the cover 5 in the axial direction with little play so that they can not move.
- the hub 13 has an outer toothing 14 in the region of its portion facing the intermediate disk 6.
- the hub integrally formed includes a plurality of wings 15, which thus form together with the hub 13, the turbine wheel.
- the outer edges 16 of the wings 15 lie on a circle having a radius which corresponds approximately to the radius of a cross section through the widened part of the water inlet 1.
- openings 17 are arranged in the lid 5 within the area where the water inlet 1 is connected to the lid 5. These openings are inclined; namely, if one follows the arrangement of the openings 17, all in the same direction obliquely. This is on the FIG. 4 refer to a section through the extended part of the water inlet along line IV-IV in FIG. 3 shows. If one follows the individual openings 17 in the counterclockwise direction, the openings are all inclined in the same direction, so that the water jet emerging from the openings 17 below the cover 5 impinges on all the wings 15 in the same direction. This means that the water entering through the openings 17 causes the turbine to rotate.
- FIG. five shows a broken section along line V-V in Figure two.
- the left half of the section through the chambers 8 is placed in the right half of the intersection between the washer 6 and the lid is five. It thus shows a plan view of the intermediate disk 6 with the inlet openings 11.
- This wall now contains at the same height as the external teeth 14 of the hub 13 an inwardly directed sprocket 18, which extends over the entire circumference of this wall 7.
- a valve closing member 19 is arranged in the form of a flat circular disc 20 in the illustrated embodiment.
- This valve closing disc 20 has a ring gear 21 along its circumference. This ring gear 21 meshes with both the inwardly directed ring gear 18 and with the ring gear 14 of the hub 13. Upon rotation of the hub 13, caused by the flowing water, thus also the valve closing disc 20 is rotated so that it on the internal teeth 18th rolls.
- valve closure plate 20 closes in the course of a cycle, that is a complete revolution, successively the inlet openings 11 to each chamber eighth
- valve closing disc 20 is present, for example two or three.
- the ribs 10 between the individual chambers extend radially outwardly from a center of the circular arrangement, so that the chambers formed between them are formed in the shape of a sector of a circle.
- FIGS. 6 and 7 show in a perspective view a shower head once obliquely from below and even diagonally from above.
- the shape of the shower head is the same as in the previous embodiment, but the jet outlet openings are also optically combined into groups of jet outlet openings 3 in the jet disk 2.
- the inlet again takes place from above, that is to say from the top side opposite the jet exit disk 2.
- a water inlet 1 is present, in the interior of three slots 23 are provided, through which the water flows into the interior of the shower head.
- a turbine 24 is arranged immediately behind the three slots 23, which is driven by the water flowing into the shower head.
- the turbine drives via a detent gear 25 a diametrically extending through the housing axis 26 at.
- the axis 26 is mounted at its two ends in the housing of the shower head. It has two valve closing bodies in the form of discs 27. These discs 27 extend over approximately a three-quarter arc, so have a gap. The gaps of both disks 27 are arranged at different locations along the circumference.
- the axis 26 with the valve closing bodies 27 is arranged in a valve space 28 into which leads approximately in the middle of the inlet for the water.
- the valve chamber 28 has a cylindrical shape and abut the peripheral surfaces of the valve discs 27 on the wall. From the valve space 28 valve openings 30 lead to a group of jet outlet openings 3.
- the discs 27 have a thickness which is greater than the diameter of the valve openings 30.
- the discs 27 are arranged in the axial direction on the axis 26 at the locations at which the valve openings 30 lead to the chambers 31 containing the jet outlet openings 3. This one is best in FIG. 10 detect. If, by rotating the axle 26, the valve disks 27 rotate, they cover the valve openings 30 over part of their circumference, whereas where the gaps are present, the inlet into the opening 30 and thus into the chambers 31 is opened.
- the axis 26 can be adjusted or even move. This stepless displacement then affects all chambers.
- the discs 27 are formed as flat discs, so that the opening operation and the closing operation through the gap in the disc 27 is achieved. It is also conceivable to allow the disks to run obliquely to the axis, so that the contact surface between the periphery of the disks and the wall of the valve chamber 28 moves back and forth in the axial direction.
- FIG. 11 one of the FIG. 10 corresponding section, in which the drive of the axis 26 takes place from the side, ie from the axial direction of the axis.
- a turbine 24 is also arranged behind an inlet, wherein between the turbine 24 and the axis 26 rotated by it, a reduction gear 25 is arranged.
- this facility works in similar to the previous one.
- FIG. 12 shows a section where two lying on opposite sides of the axis 26 chambers 31 are supplied with water, while in the position of FIG. 13 only the right chamber 31 is supplied with water.

Abstract
Description
Die Erfindung geht aus von einem Brausekopf mit einem Brausekopfgehäuse, einem Wassereinlass und einer Strahlaustrittsscheibe.The invention relates to a shower head with a shower head housing, a water inlet and a jet exit disc.
Es ist bereits ein Brausekopf bekannt, in dem eine Turbine angeordnet ist, die zu einer periodischen Bewegung des Strahlaustrittskörpers gegenüber dem Brausekopfgehäuse führt (
Bei einer weiteren bekannten Brauseeinrichtung macht die Strahlaustrittsscheibe eine exzentrische Bewegung, ohne sich zu verdrehen. Die als Hülsen aus elastischem Material bestehenden Strahlaustrittselemente bewegen sich dabei auf einem Kegel, wobei alle Strahlaustrittselemente parallel zueinander bleiben (
Ebenfalls bekannt sind Massagebrausen, bei denen Strahlaustrittsöffnungen in sehr schneller Folge geöffnet und geschlossen werden. Dabei soll ein pulsierender Strahl geschaffen werden, der eine Massagewirkung beim Auftreffen auf der Haut erzeugen soll.Also known are massage showers in which jet outlet openings are opened and closed in a very fast sequence. In this case, a pulsating beam is to be created, which should produce a massage effect when hitting the skin.
Der Erfindung liegt die Aufgabe zu Grunde, einen Brausekopf zu schaffen, bei dem auch bei einer großflächigen Abstrahlung ohne zusätzlichen Wasserverbrauch kräftige Wasserstrahlen erzeugt werden..The invention is based on the object to provide a shower head, in which even with a large-scale radiation without additional water consumption strong water jets are generated.
Zur Lösung dieser Aufgabe schlägt die Erfindung einen Brausekopf mit den im Anspruch 1 genannten Merkmalen vor. Weiterbildungen der Erfindung sind Gegenstand der abhängigen Patentansprüche.To solve this problem, the invention proposes a shower head with the features mentioned in
Der Brausekopf nach der Erfindung enthält also zwei getrennte Kammern, aus denen das Wasser durch die Strahlaustrittsöffnungen der Strahl austritt Scheibe ausströmen kann. Diese Kammern sind so voneinander getrennt, das ist möglich ist, eine der beiden Kammern mit Wasser zu versorgen, während die andere Kammer nicht mit Wasser versorgt wird. Das Wasser kann also nicht von einer Kammer in die andere Kammer fließen. Durch die Ventileinrichtung, die die Kammern öffnen und schließen kann, wird es dann möglich, eine Kammer getrennt von einer anderen Kammer mit Wasser zu versorgen. Beim Umschalten treten dann aus allen Strahlaustrittsöffnungen einer Kammer gleichzeitig plötzlich Wasserstrahlen aus, beziehungsweise werden abgeschaltet. Es wird also nicht eine Strahlaustrittsöffnung nach der anderen ein- beziehungsweise ausgeschaltet, sondern immer eine ganze Gruppe von Strahlaustrittsöffnungen.The shower head according to the invention thus contains two separate chambers from which the water can flow out through the jet outlet openings of the jet disc. These chambers are so separated, it is possible to provide one of the two chambers with water, while the other chamber is not supplied with water. So the water can not flow from one chamber to the other. By the valve means, which can open and close the chambers, it is then possible to supply a chamber separately from another chamber with water. When switching then suddenly occur from all the beam outlet openings of a chamber water jets, or be switched off. It is therefore not one jet outlet opening after the other switched on or off, but always a whole group of jet outlet openings.
Durch das zeitweise Abschalten der Strahlöffnungen einer Kammer wird der Durchfluss insgesamt erniedrigt, was gleichzeitig einen Anstieg des Innendrucks und damit eine Verstärkung der austretende Wasserstrahlen bewirkt.By temporarily switching off the jet openings of a chamber, the flow is reduced overall, which simultaneously causes an increase in the internal pressure and thus an amplification of the exiting water jets.
In Weiterbildung der Erfindung kann vorgesehen sein, dass die Ventileinrichtung mindestens einen Ventilschließkörper aufweist, der mit einem Einlass in mindestens zwei, vorzugsweise alle Kammern zusammenwirkt. Es gibt in diesem Fall also mindestens einen Ventilschließkörper, der aber dann für mindestens zwei, insbesondere aber alle Kammern zuständig ist. Dadurch vereinfacht sich der Aufbau der Ventileinrichtung.In a further development of the invention it can be provided that the valve device has at least one valve closing body which cooperates with an inlet in at least two, preferably all chambers. In this case, therefore, there is at least one valve closing body, which, however, is then responsible for at least two, but in particular all chambers. This simplifies the construction of the valve device.
Es ist ebenfalls möglich, dass die Ventileinrichtung mehrere Ventilschließkörper aufweist. Auch dann kann vorgesehen sein, dass mindestens ein Ventilschließkörper mit dem Einlass in alle Kammern zusammenwirkt.It is also possible that the valve device has a plurality of valve closing bodies. Also then it can be provided that at least one valve closing body cooperates with the inlet in all chambers.
Eine weitere Möglichkeit besteht darin, dass bei mehreren Ventilschließkörpern für mindestens eine Kammer ein eigener Ventilschließkörper vorhanden ist, der nicht mit den anderen Kammern zusammenwirkt.Another possibility is that with several valve closing bodies for at least one chamber, a separate valve closing body is present, which does not interact with the other chambers.
Um die erwähnte Wirkung des schlagartigen Einschaltens beziehungsweise Abschaltens aller Strahlaustrittsöffnungen der Kammer zu begünstigen, kann in Weiterbildung vorgesehen sein, dass diese Kammer nur einen Einlass aufweist.In order to promote the mentioned effect of the sudden switching on or switching off of all the jet outlet openings of the chamber, it can be provided in a development that this chamber has only one inlet.
Für den Antrieb kann erfindungsgemäß vorgesehen sein, dass unmittelbar hinter dem Einlass in das Brausekopfgehäuse eine Turbine angeordnet ist, die über ein Getriebe oder direkt mit dem Ventilschließkörper verbunden ist.For the drive can be inventively provided that immediately behind the inlet into the shower head housing, a turbine is arranged, which is connected via a gear or directly to the valve closing body.
In Weiterbildung der Erfindung kann vorgesehen sein, dass das Brausekopfgehäuse eine insbesondere kreisrunde Strahlaustrittsscheibe aufweist, wobei die Kammern die Grundfläche eines Kreissektors aufweisen. Auf diese Weise kann dafür gesorgt werden, dass die gesamte Grundfläche der Strahlaustrittsscheibe für Öffnungen zur Verfügung steht, und dass es möglich wird, einen rotierenden Ventilschließkörper zu verwenden.In a development of the invention, it can be provided that the showerhead housing has a particularly circular jet exit disc, wherein the chambers have the base area of a circular sector. In this way it can be ensured that the entire base area of the jet exit disk is available for openings, and that it becomes possible to use a rotating valve closing body.
In Weiterbildung der Erfindung kann vorgesehen sein, dass die Einlässe in die Kammern längs eines Kreisbogens angeordnet werden.In a further development of the invention it can be provided that the inlets are arranged in the chambers along a circular arc.
Erfindungsgemäß kann vorgesehen sein, dass die Kammern einerseits von der Strahlaustrittsscheibe und andererseits einer Zwischenscheibe begrenzt sind. Auf diese Weise lässt sich das Gehäuse sehr einfach zusammensetzen, vor allen Dingen dann, wenn sowohl die Strahlaustrittsscheibe auf ihrer Innenseite als auch die Zwischenscheibe die gleiche Form aufweisen, beispielsweise als ebene Scheiben ausgebildet sind Erfindungsgemäß kann vorgesehen sein, dass mindestens ein Ventilschließkörper als flache auf der dem Wassereinlass zugewandten Seite der Zwischenscheibe aufliegende Scheibe ausgebildet ist. Sie kann auf dieser Scheibe verschoben werden und direkt mit einer Einlassöffnung für die Kammer in der Zwischenscheibe zusammen wirken.According to the invention it can be provided that the chambers are bounded on the one hand by the jet exit disc and on the other hand by an intermediate disc. In this way, the housing can be very easy to assemble, especially when both the jet exit disc on its inside and the washer have the same shape, for example, are formed as flat slices According to the invention, it can be provided that at least one valve closing body is formed as a flat washer resting on the side of the intermediate disk facing the water inlet. It can be moved on this disc and interact directly with an inlet opening for the chamber in the washer.
Insbesondere kann dabei vorgesehen sein, dass die Verschließscheibe eine Randverzahnung aufweist, die mit einem mit der Turbine verbundenen Zahnkranz kämmt.In particular, it may be provided that the closing disc has an edge toothing, which meshes with a ring gear connected to the turbine.
In Weiterbildung der Erfindung kann vorgesehen sein, dass die Verschließscheibe eine Randverzahnung aufweist, die mit einer an der Innenseite des Brausekopfgehäuses längs des gesamten Umfangs angeordneten Verzahnung in Eingriff steht.In a further development of the invention can be provided that the closing disc has a peripheral toothing, which is arranged with a arranged on the inside of the shower head housing along the entire circumference toothing.
Insbesondere kann vorgesehen sein, dass die Randverzahnung der Verschließscheibe sowohl mit der Turbine als auch mit dem gehäuseseitigen Zahnkranz in Eingriff steht.In particular, it can be provided that the edge toothing of the closing disc is engaged both with the turbine and with the housing-side toothed ring.
Erfindungsgemäß kann vorgesehen sein, dass die sich verschiebende und rotierende Verschließscheibe keine eigene Lagerung aufweist.According to the invention, it can be provided that the sliding and rotating closing disc does not have its own bearing.

Hinter der Strahlaustrittsscheibe 2 ist eine Zwischenscheibe 6 angeordnet, die als ebene Scheibe ausgebildet ist und somit parallel zur Innenseite der Strahlaustrittsscheibe 2 verläuft. Diese Zwischenscheibe 6 weist einen hochgezogenen Rand 7 auf, der mit seiner Außenseite an der Innenseite des Mantels 4 anliegt.Behind the
Zwischen der Strahlaustrittsscheibe 2 und der Zwischenscheibe 6 sind einzelne Kammern 8 ausgebildet. Sie reichen von einer Stelle 9 benachbart zum Mittelpunkt des Querschnitts des Gehäuses bis an der Innenseite der Außenwand 4. Die einzelnen Kammern sind durch Rippen 10 voneinander getrennt, auf denen die Zwischenscheibe 6 aufliegt. In
Während die Zwischenscheibe 6 auf ihrer der Strahlaustrittsscheibe 2 zugewandten Seite eben ausgebildet ist, so dass sie auf der Oberfläche der Rippen 10 vollständig und damit auch dichtend aufliegt, enthält sie auf ihrer dem Wassereinlass 1 zugewandten Seite in der Mitte einen Lagerzapfen 12. Auf dem Lagerzapfen 12 ist die Nabe 13 einer Turbine gelagert. Die Nabe 13 ist zwischen der Zwischenscheibe 6 und dem Deckel 5 in Axialrichtung mit geringem Spiel so festgelegt, dass sie sich nicht verschieben kann. Die Nabe 13 weist im Bereich ihres der Zwischenscheibe 6 zugewandten Abschnitts eine Außenverzahnung 14 auf. In dem Bereich oberhalb der Außenverzahnung 14 enthält die Nabe einstückig angeformt mehrere Flügel 15, die somit zusammen mit der Nabe 13 das Turbinenrad bilden. Die Außenkanten 16 der Flügel 15 liegen auf einem Kreis mit einem Radius, der etwa dem Radius eines Querschnitts durch den erweiterten Teil des Wassereinlasses 1 entspricht.While the
Um die Turbine in Drehung zu versetzen, sind in dem Deckel 5 innerhalb des Bereichs, wo der Wassereinlass 1 mit dem Deckel 5 verbunden ist, vier Öffnungen 17 angeordnet. Diese Öffnungen verlaufen schräg; und zwar, wenn man der Anordnung der Öffnungen 17 folgt, alle in der gleichen Richtung schräg. Hierzu wird auf die
Im folgenden wird auf die Figur fünf verwiesen, die einen abgebrochenen Schnitt längs Linie V-V in Figur zwei zeigt. In der linken Hälfte ist der Schnitt durch die Kammern 8 gelegt, in der rechten Hälfte liegt der Schnitt zwischen der Zwischenscheibe 6 und dem Deckel fünf. Er zeigt also eine Draufsicht auf die Zwischenscheibe 6 mit den Einlassöffnungen 11.Reference is now made to the figure five, which shows a broken section along line V-V in Figure two. In the left half of the section through the
Es wurde bereits erwähnt, dass die Zwischenscheibe 6 mit ihrem Rand an der Innenseite der Außenwand 4 anliegt. Diese Wand enthält nun auf der gleichen Höhe wie die Außenverzahnung 14 der Nabe 13 einen nach innen gerichteten Zahnkranz 18, der sich über den gesamten Umfang dieser Wand 7 erstreckt. Zwischen dem Zahnkranz 14 der Nabe 13 und dem inneren Zahnkranz 18 der Wand 7 ist im dargestellten Ausführungsbeispiel ein Ventilschließkörper 19 in Form einer ebenen kreisrunden Scheibe 20 angeordnet. Diese Ventilschließscheibe 20 weist längs ihres Umfangs einen Zahnkranz 21 auf. Dieser Zahnkranz 21 kämmt sowohl mit dem nach innen gerichteten Zahnkranz 18 als auch mit dem Zahnkranz 14 der Nabe 13. Bei einer Verdrehung der Nabe 13, hervorgerufen durch das strömende Wasser, verdreht sich somit auch die Ventilschließscheibe 20, so dass sie auf der Innenverzahnung 18 abrollt. In der in
Es ist möglich, dass bei einer solchen Anordnung mehr als eine Ventilschließscheibe 20 vorhanden ist, beispielsweise zwei oder drei.It is possible that in such an arrangement more than one
Um die Dauer des Verschlossenseins der Einlassöffnungen 11 in einem gewissen Ausmaß zu ändern, ist es möglich, diese Einlassöffnungen 11 näher an der Nabe 13 oder näher an die Außenseite heranzurücken.In order to change the duration of the closing of the
Die Rippen 10 zwischen den einzelnen Kammern verlaufen von einem Mittelpunkt der kreisrunden Anordnung radial nach außen, so dass die zwischen ihnen gebildeten Kammern kreissektorförmig ausgebildet sind. Strahlaustrittsöffnungen gibt es über die gesamte Fläche der Strahlaustrittscheibe 2, so dass alle Strahlaustrittsöffnungen 3 mit Wasser versorgt werden können.The

Bei der dargestellten Ausführungsform sind die Scheiben 27 als ebene Scheiben ausgebildet, so dass der Öffnungsvorgang und der Schließvorgang durch die Lücke in der Scheibe 27 erreicht wird. Es ist auch denkbar, die Scheiben schräg zur Achse verlaufen zu lassen, so dass die Berührungsfläche zwischen dem Umfang der Scheiben und der Wand des Ventilraums 28 in axialer Richtung hin und her wandert.In the illustrated embodiment, the

Auf der Innenseite des die Strahlaustrittsscheibe 2 und den Mantel 3 des Gehäuses bildenden Bauteils ist eine Randstufe 41 gebildet: Mit Abstand von dieser Randstufe 41 ist auf der Innenseite der Strahlaustrittsscheibe ein Ringsteg 42 angeformt, der die gleiche Höhe wie die Stufe 41 aufweist. Ein Teil der Strahlaustrittsöffnungen 4 ist in dem Raum zwischen dem Ringsteg 42 und der Außenwand 3 des Gehäuses angeordnet, während ein anderer Teil der Strahlaustrittsöffnungen 4 innerhalb des Ringstegs 42 angeordnet ist. Auf die Schulter 41 und den Ringsteg 42 ist ein Zwischenboden 43 aufgelegt, der dadurch eine erste Kammer 44 zwischen dem Mantel 3, der Strahlscheibe 2 und dem Ringsteg 42 und eine zweite Kammer 45 zwischen dem Ringsteg 42 und der Strahlaustrittsscheibe 2 bildet. Aus jeder der beiden Kammern 44, 45 führen Strahlaustrittsöffnungen 3 ins Freie.On the inside of the
Der Zwischenboden 43 weist einen Einlass 46 in die äußere Kammer 44 und einen Einlass 47 in die innere Kammer 45 auf. In der Mitte weist der Zwischenboden 43 auf der der Strahlaustrittsscheibe 2 abgewandten Seite einen Lagerzapfen 6 auf, auf dem ein Bauteil 48 drehbar gelagert ist. Dieses Bauteil 48 weist eine Vielzahl von radial verlaufenden Flügeln 49 auf, die bis fast an die Außenseite des Gehäuses reichen. Das aus den Kanälen 40 austretende Wasser trifft auf die Flügel 49 und versetzt dieses Bauteil 48 in Drehung. Das Bauteil 48 weist an der Unterseite seiner Flügel 49 zwei Teilringplatten 50, 51 auf, die sich jeweils über etwa einen halben Umfang erstrecken. Die äußere Platte 50 ist so angeordnet, dass ihre Außenkante außerhalb der Außenkante der Einlassöffnung 46 und ihre Innenkante auf einem Kreis innerhalb der inneren Seite der Einlassöffnung 46 liegt. Dies bedeutet, dass diese Platte 50 den Einlass 46 in die äußere Kammer 44 verschließen kann. Das gleiche gilt für die innere Teilringplatte 51, die dementsprechend dem Einlass 47 in die innere Kammer 45 zugeordnet ist.The intermediate bottom 43 has an
