Abstract

A flushing device comprising an evacuation fitting (6) that is provided with a sealing member (7) within a pressurized container (2). The sealing member (7) is lifted counter to the pressure of a piston (16) in order to initiate the flushing process. A connecting device (39) for a water pipe (24) is disposed on the container (2). The flushing device further comprises a structure (49, 50) for flushing with a partial quantity of the flushing water. For example, the structure (49, 50) is provided with a power-loaded part (50) which moves the valve member (7) down onto the valve seat (5) of the evacuation fitting (6) when the flushing process is interrupted. In an alternative embodiment, two chambers are provided, only one of which is emptied during partial flushing. Flushing water can be conserved by the fact that the flushing process can be interrupted.

Description

Die Erfindung betrifft eine Spülvorrichtung nach dem Oberbegriff des Anspruchs 1.The invention relates to a flushing device according to the preamble of claim 1.

Spülvorrichtungen der genannten Art sind seit langem bekannt und werden auch als Druckspülkasten bezeichnet. Bei diesen Spülvorrichtungen steht das im Behälter zur Spülung vorliegende Wasser im Ruhezustand unter dem Druck eines über dem Wasser vorhandenen Druckraumes. Der Druckraum enthält Luft, die den Behälter nicht verlassen kann und einen Überdruck aufweist. Der Überdruck wird beim Nachfüllen des Spülkastens erzeugt. Bei einer Spülauslösung wird der Verschlusskörper der Ablaufarmatur angehoben und das im Behälter vorliegende Spülwasser wird unter Entspannung der Luft des Druckraumes in eine Klosettschüssel abgegeben. Das Spülwasser verlässt den Behälter somit nicht nur aufgrund seines Eigengewichts, sondern zusätzlich unter der Wirkung des Druckraumes. Der Druck im Behälter bewirkt, dass das Spülwasser mit erhöhter Geschwindigkeit bei einer Spülung abgegeben wird. Ein Beispiel einer solchen Spülvorrichtung ist aus der US 6,343,387 B1 bekannt geworden. Der Vorteil solcher Spülvorrichtungen liegt insbesondere darin, dass mit vergleichsweise wenig Wasser oder hoher Energie gespült werden kann.Flushing devices of the type mentioned have long been known and are also referred to as Druckspülkasten. In these flushing devices, the water present in the tank for flushing is at rest under the pressure of an existing pressure chamber above the water. The pressure chamber contains air that can not leave the container and has an overpressure. The overpressure is generated when refilling the cistern. In a rinsing trigger the closure body of the drain fitting is raised and the rinse water present in the container is discharged while relaxing the air of the pressure chamber in a toilet bowl. The rinse water thus leaves the container not only due to its own weight, but also under the effect of the pressure chamber. The pressure in the container causes the rinse water to be released at an increased rate in a rinse. An example of such a flushing device is from the US 6,343,387 B1 known. The advantage of such flushing devices is in particular that it can be flushed with comparatively little water or high energy.

Aus der US 2,957,181 ist zudem eine Spülvorrichtung bekannt geworden, bei welcher eine Spiralfeder vorgesehen ist, mit der in einer Kammer Spülwasser unter Druck gehalten wird. Bei einer Spülung wird das Spülwasser unter Entspannung der Spülfeder ausgestossen.From the US 2,957,181 In addition, a flushing device has become known, in which a spiral spring is provided with which flushing water is kept under pressure in a chamber. at a rinse, the rinse water is ejected under relaxation of the rinsing spring.

Die US 1,645,264 offenbart eine Spülvorrichtung mit einer unter Druck stehenden Kammer. Im unteren Bereich der Kammer ist ein Auslaufventil mit einem Ventilkörper angeordnet, der über eine Stange mit einem Hebel verbunden ist. Durch Verschwenken des Hebels kann der Ventilkörper angehoben und damit eine Spülung ausgelöst werden. Beim Anheben des Ventilkörpers wird eine Feder gespannt. Wird der Hebel losgelassen, so wird der Ventilkörper nach unten auf den Ventilsitz bewegt und der Hebel in die Ausgangsstellung verschwenkt. Durch entsprechend langes Halten des Hebels kann mit jeder beliebigen Wassermenge gespült werden. Jede Spülmenge ist abhängig von der Zeit, während welcher das Ventil offengehalten wird. Dadurch wird praktisch nie mit der optimalen Wassermenge gespült. Der Wasserverbrauch ist bei solchen Spülvorrichtungen regelmässig zu hoch oder es wird mit zu wenig Wasser gespült, was aus hygienischen Gründen nachteilig ist.The US 1,645,264 discloses a flushing device with a pressurized chamber. In the lower part of the chamber, an outlet valve with a valve body is arranged, which is connected via a rod with a lever. By pivoting the lever, the valve body can be raised and thus a flushing triggered. When lifting the valve body, a spring is tensioned. When the lever is released, the valve body is moved down onto the valve seat and the lever is pivoted to the starting position. By holding the lever for a long time, you can flush with any amount of water. Each purge quantity is dependent on the time during which the valve is kept open. This practically never rinses with the optimum amount of water. The water consumption is regularly too high in such flushing devices or it is flushed with too little water, which is disadvantageous for hygienic reasons.

Die DE 31 30 452 A offenbart eine Spülvorrichtung, die einen Spülkasten und im Zulauf zum Spülkasten einen Druckspüler aufweist. Wahlweise kann mit dem Spülkasten oder mit dem Druckspüler gespült werden.The DE 31 30 452 A discloses a flushing device having a cistern and in the inlet to the cistern a flush valve. Optionally, it can be rinsed with the cistern or with the flush valve.

Die gattungsbildende GB 497 765 A offenbart einen Spülkasten, bei dem der Verschlusskörper des Auslaufventils mit einem zweiarmigen Hebel unterschiedlich hoch angehoben werden kann, so dass das Auslaufventil innerhalb von unterschiedlichen Zeitdauern schliesst und unterschiedliche Spülwassermengen abgegeben werden.The generic GB 497 765 A discloses a cistern in which the closure body of the outlet valve with a two-armed lever can be raised to different heights, so that the outlet valve closes within different time periods and different amounts of flushing water are discharged.

Die WO 02/077377 A bildet einen Stand der Technik nach Artikel 54(3) EPÜ und offenbart einen Druckspülkasten mit wenigstens einem Druckbehälter. Dieser besitzt einen verriegelten federbelasteten Druckkolben, der lösbar verriegelt ist. Zur Spülauslösung wird der Druckkolben entriegelt und damit das im Druckbehälter vorhandene Wasser ausgestossen.The WO 02/077377 A constitutes prior art under Article 54 (3) EPC and discloses a pressurized cistern with at least one pressure vessel. This has a locked spring-loaded Pressure piston, which is releasably locked. For rinsing the pressure piston is unlocked and thus ejected the water present in the pressure vessel.

Der Erfindung liegt die Aufgabe zugrunde, eine Spülvorrichtung der genannten Art zu schaffen, die eine noch weitere Einsparung an Spülwasser ermöglicht. Die Aufgabe ist bei einer gattungsgemässen Spülvorrichtung gemäss Anspruch 1 gelöst. Die Spülvorrichtung weist Mittel zur Spülung mit einer Teilmenge des Spülwassers auf. Bei der erfindungsgemässen Spülvorrichtung kann der Spülvorgang unterbrochen werden. Dadurch ist es möglich, wahlweise eine Voll- oder Teilspülung durchzuführen. Es ist somit nicht in allen Fällen erforderlich, mit der ganzen im Behälter vorliegenden Spülwassermenge zu spülen. Es kann auch mit einer Teilmenge des vorliegenden Wassers gespült werden, wo eine solche Teilmenge zur Spülung ausreichend ist. Dies ist in der Praxis in vielen Fällen möglich, sodass mit der erfindungsgemässen Spülvorrichtung sehr viel Wasser und insbesondere Frischwasser gespart werden kann, was aus wirtschaftlicher und ökologischer Hinsicht ein erheblicher Fortschritt ist.The invention has for its object to provide a flushing device of the type mentioned, which allows a further saving of flushing water. The object is achieved in a generic flushing device according to claim 1. The flushing device has means for flushing with a subset of the flushing water. In the inventive flushing device, the flushing process can be interrupted. This makes it possible to carry out either a full or partial flush. It is therefore not necessary in all cases to rinse with the entire amount of flushing water present in the container. It can also be rinsed with a subset of the water present where such a subset is sufficient for rinsing. In practice, this is possible in many cases, so that a great deal of water, and in particular fresh water, can be saved with the flushing device according to the invention, which is a considerable advance from an economic and ecological point of view.

Die Unterbrechung der Spülung kann beliebig oder auch fest eingestellt sein. Bei einer festen Einstellung ist die Spülmenge bei einer Teilmenge bestimmt und beträgt beispielsweise 3 l. Die Auslösung kann mechanisch oder auch berührungslos sein. Die Spülvorrichtung eignet sich auch insbesondere für eine automatische Toilettenanlage, bei welcher beispielsweise Sensoren selbsttätig eine Voll- oder Teilspülung auslösen.The interruption of the flushing can be set arbitrarily or fixed. With a fixed setting, the flushing amount is determined for a subset and is for example 3 l. The triggering can be mechanical or non-contact. The flushing device is also particularly suitable for an automatic toilet system, in which, for example, sensors automatically trigger a full or partial flush.

Nach der Erfindung ist vorgesehen, dass die Spülvorrichtung einen kraftbelasteten Teil aufweisen, der bei einer Spülunterbrechung den Ventilkörper nach unten auf den Ventilsitz bewegt. Dies ermöglicht mit vergleichsweise einfachen Mitteln eine schnelle Unterbrechung während unterschiedlichen Phasen der Spülung.According to the invention, it is provided that the flushing device have a force-loaded part which moves the valve body downwards onto the valve seat during a flushing interruption. This allows for comparatively simple Means a quick break during different phases of flushing.

Der kraftbelastete Teil ist gemäss einer Weiterbildung der Erfindung in der Ablaufarmatur verschieblich gelagert. Dies ermöglicht eine besonders kompakte Ausführung und hat den besonderen Vorteil, dass die Montage der Spülvorrichtung nicht aufwändiger ist als vorher. Der Teil ist fest in der Ablaufarmatur integriert und wird bei der Montage dieser Armatur ohne weitere Montageschritte installiert.The force-loaded part is slidably mounted according to a development of the invention in the drain fitting. This allows a particularly compact design and has the particular advantage that the installation of the flushing device is not more complex than before. The part is permanently integrated in the drain fitting and is installed during assembly of this valve without any further assembly steps.

Nach einer Weiterbildung ist vorgesehen, dass der kraftbelastete Teil federbelastet ist. Dieser Teil wird beispielsweise mit einer Rastvorrichtung im gespannten Zustand gehalten. Nach dem Lösen der Rastvorrichtung wirkt der Teil unter Kraft der Feder auf den Verschlusskörper und zwingt diesen in die Schliessstellung.According to a development, it is provided that the force-loaded part is spring-loaded. This part is held, for example, with a locking device in the tensioned state. After releasing the locking device of the part acts under the force of the spring on the closure body and forces it into the closed position.

Nach einer Weiterbildung der Erfindung ist der kraftbelastete Teil im genannten Kolben gelagert. Beim Nachfüllen des Spülkastens wird der kraftbelastete Teil in eine Ausgangsstellung bzw. Ruhestellung gebracht, wobei beispielsweise eine Druckfeder gespannt wird. Die Druckfeder kann hierbei durch ein anderes Kraftmittel, beispielsweise ein Gewicht oder ein Magnet ersetzt sein.According to a development of the invention, the force-loaded part is mounted in said piston. When refilling the cistern, the force-loaded part is brought into a starting position or rest position, for example, a compression spring is tensioned. The compression spring can in this case be replaced by another force means, for example a weight or a magnet.

Die in Figur 1 gezeigte Spülvorrichtung 1 weist einen Behälter 2 auf, der ein Druckbehälter ist und beispielsweise aus zwei miteinander verbundenen schalenförmigen Hälften 2a und 2b besteht. Der Behälter 2 ist beispielsweise für einen Innendruck von 2 bar ausgelegt. In einem Boden 40 des Behälters 2 befindet sich eine Auslauföffnung 38, die in einen Stutzen 3 führt, der über einen hier nicht gezeigten Spülbogen mit einer hier ebenfalls nicht gezeigten Toilettenschüssel verbunden ist. Über der Auslauföffnung 38 ist eine Ablaufarmatur 6 angeordnet, die einen Verschlusskörper 7 aufweist, der in einem Führungsrohr 9 verschieblich gelagert ist und der in einem unteren Ende einen Dichtungsring 41 aufweist, welcher bei geschlossener Ablaufarmatur 6 auf einem Ventilsitz 5 aufliegt.The rinsing device 1 shown in Figure 1 comprises a container 2, which is a pressure vessel and consists for example of two interconnected bowl-shaped halves 2a and 2b. The container 2 is designed, for example, for an internal pressure of 2 bar. In a bottom 40 of the container 2 is an outlet opening 38 which leads into a nozzle 3, which is connected via a rinsing sheet not shown here with a toilet bowl, also not shown here. About the outlet opening 38, a drain fitting 6 is arranged, which has a closure body 7, which is displaceable in a guide tube 9 is mounted and having a sealing ring 41 in a lower end, which rests with a closed drain fitting 6 on a valve seat 5.

Der Behälter 2 ist gemäss Figur 1 in der Ruhestellung mit Spülwasser 14 gefüllt. Über der Oberfläche 42 des Spülwassers 14 befindet sich ein Druckraum 15, der Luft enthält. Die Luft besitzt einen Überdruck, welcher auf die Oberfläche 42 des Spülwassers 14 wirkt. Der Druck beträgt beispielsweise 3 bar. In das Spülwasser 14 taucht eine Entlüftungsleitung 18, die an einem oberen Ende 18a zur Umgebung offen ist und in welcher ein Entlüftungsventil 19, beispielsweise ein Kugelventil, angeordnet ist. Die Entlüftungsleitung 19 dient ebenfalls zum Nachfüllen des Behälters 2 und besitzt unterhalb des Entlüftungsventils 19 gemäss Figur 3 einen Durchgang 43 in einen Innenraum 44 einer Anschlussvorrichtung 39. Der Druckraum 15 umfasst lediglich ein Teilvolumen des Behälters 2, das im oberen Bereich des Behälters 2 angeordnet ist. Die Entlüftungsleitung 18 taucht mit einem unteren offenen Ende 18b in das Spülwasser 14.The container 2 is filled according to Figure 1 in the rest position with rinse water 14. Above the surface 42 of the rinse water 14 is a pressure chamber 15 containing air. The air has an overpressure which acts on the surface 42 of the rinse water 14. The pressure is for example 3 bar. In the rinse water 14 dives a vent line 18 which is open at an upper end 18a to the environment and in which a vent valve 19, for example, a ball valve, is arranged. The vent line 19 also serves to refill the container 2 and has below the vent valve 19 according to Figure 3, a passage 43 in an interior 44 of a connecting device 39. The pressure chamber 15 includes only a partial volume of the container 2, which is arranged in the upper region of the container 2 , The vent line 18 dives with a lower open end 18 b in the rinse water 14th

Die Anschlussvorrichtung 39 dient für den Anschluss einer Druckwasserleitung 24, in der beispielsweise ein dauernder Wasserdruck von etwa 3 bar besteht. Die Anschlussvorrichtung 39 weist ein Druckregulierventil 45 auf, das die Druckwasserleitung 24 mit dem Innenraum 44 verbindet und in einem Ventilraum 20 eine Ventilkugel 21 aufweist, die mit einem Ventilkolben 22 zusammenarbeitet, der von einer Zugfeder 23 gegen die Ventilkugel 21 gespannt wird. In der Figur 1 ist das Druckregulierventil 45 geschlossen.The connection device 39 serves for the connection of a pressurized water line 24 in which there is, for example, a continuous water pressure of about 3 bar. The connecting device 39 has a pressure regulating valve 45, which connects the pressurized water line 24 with the interior 44 and in a valve chamber 20 has a valve ball 21 which cooperates with a valve piston 22 which is tensioned by a tension spring 23 against the valve ball 21. In the figure 1, the pressure regulating valve 45 is closed.

Der Verschlusskörper 7 besitzt an seinem oberen Ende einen Kolben 16 mit einem Innenraum 17, der gegen oben offen ist. Dieser Innenraum 17 ist über einen Strömungsspalt 46 mit dem Innenraum 44 verbunden. Der Innenraum 17 ist somit mit Wasser gefüllt, das in Figur 1 den gleichen Druck aufweist wie das Wasser im Innenraum 44 und das Spülwasser 14 im Behälter 2. Der Kolben 16 ist mit einer umlaufenden Lippendichtung 10 gegen die Innenseite des unten offenen Führungsrohrs 9 abgedichtet. Der Innenraum 17 ist an seinem unteren Ende mit einem Sicherheitsüberdruckventil 8 versehen, das eine Überdruckfeder 8a aufweist. Wird im Innenraum 17 ein maximal zulässiger Druck überschritten, so öffnet das Sicherheitsüberdruckventil 8 und gibt Wasser über die Aüslauföffnung 38 nach aussen ab. Bei geschlossener Ablaufarmatur 6 gemäss Figur 1 wird der Verschlusskörper 7 mit einer Kraft aufgrund einer Druckdifferenz von druckbeaufschlagenden Flächen gegen den Ventilsitz 5 angepresst. Bei zwei bar Innendruck im Behälter 2 beträgt diese Kraft beispielsweise sieben kp.The closure body 7 has at its upper end a piston 16 with an interior 17 which is open at the top. This interior 17 is above a flow gap 46 with the interior 44 connected. The interior 17 is thus filled with water, which has the same pressure in Figure 1 as the water in the interior 44 and the rinse water 14 in the container 2. The piston 16 is sealed with a circumferential lip seal 10 against the inside of the bottom open guide tube 9. The interior 17 is provided at its lower end with a safety pressure relief valve 8, which has a pressure spring 8a. If a maximum permissible pressure is exceeded in the interior 17, then the safety overpressure valve 8 opens and discharges water via the outlet opening 38 to the outside. When the drain fitting 6 according to FIG. 1 is closed, the closure body 7 is pressed against the valve seat 5 with a force due to a pressure difference between pressurizing surfaces. At two bar internal pressure in the container 2, this force is for example seven kp.

Der Innenraum 17 ist über ein Entlüftungsventil 11 mit einer Entlüftungsleitung 13 verbunden, die gemäss Figur 1 an einem unteren Ende 13a über den Stutzen führt. Das Entlüftungsventil 11 besitzt einen Ventilschieber 11a, der zum Schliessen bzw. Öffnen des Ventils 11 über eine Steuervorrichtung 55 mit Tasten A und B einer Betätigungsvorrichtung 56 verbunden ist. In der Figur 1 ist das Entlüftungsventil 11 geschlossen. Durch eine Betätigung der Taste A oder der Taste B in Richtung des Pfeils 47 kann das Entlüftungsventil 11 geöffnet werden. Der Innenraum 17 wird dann mit der Umgebungsluft verbunden. Mit der Taste A wird eine Vollspülung und mit der Taste B eine Teilspülung ausgelöst.The interior 17 is connected via a vent valve 11 with a vent line 13, which leads according to Figure 1 at a lower end 13a via the nozzle. The vent valve 11 has a valve slide 11 a, which is connected to close or open the valve 11 via a control device 55 with keys A and B of an actuator 56. In the figure 1, the vent valve 11 is closed. By pressing the button A or button B in the direction of arrow 47, the vent valve 11 can be opened. The interior 17 is then connected to the ambient air. With key A, a full flush is triggered and with key B a partial flush.

Wie die Figur 1 zeigt, weist die Ablaufarmatur 6 ein weiteres Führungsrohr 34 auf, das ebenfalls unten offen ist und in dem ein kolbenförmiger Teil 50 verschiebbar gelagert und mit einer Lippendichtung 30 gegen das Führungsrohr 34 abgedichtet ist. Die Figur 1 zeigt den kolbenförmigen Teil 50 in einer oberen Stellung, in welcher eine in diesem Teil 50 angeordnete Spiralfeder 49 gespannt ist. Der Teil 50 weist einen nach unten vorragenden Abschnitt 35 und an einem oberen Ende ein Verriegelungselement 31 auf. Der kolbenförmige Teil 50 ist vorzugsweise einstückig ausgebildet und beispielsweise ein Spritzgussteil aus Kunststoff. Das Verriegelungselement 31 bildet mit einem Schieber 32 eine Verriegelungsvorrichtung 48. Eine Feder 33 hält den Verriegelungsschieber 32 in der in Figur 1 gezeigten verriegelnden Position. Durch Verschieben des Schiebers 32 in Richtung des Pfeils 51 kann der kolbenförmige Teil 50 entriegelt werden, sodass er unter dem Druck der Feder 49 nach unten bewegt wird.As FIG. 1 shows, the drain fitting 6 has a further guide tube 34, which is likewise open at the bottom and in which a piston-shaped part 50 is displaceably mounted and sealed with a lip seal 30 against the guide tube 34. FIG. 1 shows the piston-shaped part 50 in an upper position, in which a arranged in this part 50 coil spring 49 is stretched. The part 50 has a downwardly projecting portion 35 and at an upper end a locking element 31. The piston-shaped part 50 is preferably formed in one piece and, for example, an injection molded part made of plastic. The locking element 31 forms with a slider 32 a locking device 48. A spring 33 holds the locking slide 32 in the locking position shown in Figure 1. By moving the slider 32 in the direction of the arrow 51, the piston-shaped part 50 can be unlocked, so that it is moved under the pressure of the spring 49 down.

Nachfolgend wird die Arbeitsweise der erfindungsgemässen Spülvorrichtung anhand der Zeichnung näher erläutert.The operation of the inventive flushing device will be explained in more detail with reference to the drawing.

Die Spülvorrichtung gemäss Figur 1 befindet sich in der Ruhestellung und ist für eine Spülung bereit. Die Luft im Druckraum 15 ist mit einem Druck von beispielsweise 2 bar gespannt. Das Druckregulierventil 39 und auch das Entlüftungsventil 19 als auch das Entlüftungsventil 11 sind geschlossen. Ebenfalls geschlossen ist die Ablaufarmatur 6. Um eine Vollspülung auszulösen, wird das Entlüftungsventil 11 durch Betätigen der Taste A geöffnet. Der Innenraum 17 wird dadurch über die Entlüftungsleitung 13 mit der Umgebungsluft verbunden. Dadurch sinkt der Druck im Innenraum 17 und der Verschlusskörper 7 bewegt sich gemäss Figur 2 in Richtung des Pfeils 25 nach oben. Die Ablaufarmatur 6 wird dadurch geöffnet und das Spülwasser 14 wird unter dem Eigengewicht und unter dem Druck des Druckraumes 15 durch die Öffnung 38 abgegeben, wie dies in Figur 2 angedeutet ist. Erreicht das Niveau 42 das untere Ende 18b der Entlüftungsleitung 18, so öffnet das Entlüftungsventil 19, sodass alles Wasser 14 aus dem Behälter 2 abgegeben werden kann.The flushing device according to FIG. 1 is in the rest position and is ready for flushing. The air in the pressure chamber 15 is stretched at a pressure of for example 2 bar. The pressure regulating valve 39 and also the venting valve 19 and the venting valve 11 are closed. Also closed is the drain fitting 6. To trigger a full flush, the vent valve 11 is opened by pressing the A key. The interior 17 is thereby connected via the vent line 13 with the ambient air. As a result, the pressure in the interior 17 drops and the closure body 7 moves according to Figure 2 in the direction of the arrow 25 upwards. The drain fitting 6 is thereby opened and the rinse water 14 is discharged under the weight and under the pressure of the pressure chamber 15 through the opening 38, as indicated in Figure 2. When level 42 reaches lower end 18b of vent line 18, vent valve 19 opens so that all water 14 can be dispensed from reservoir 2.

Ist alles Spülwasser 14 aus dem Behälter 2 entwichen, so herrscht im Behälter 2 kein Überdruck mehr. Das Wasser im Innenraum 17 wird nicht als Spülwasser verwendet und bleibt in diesem Innenraum 17. Dadurch sinkt der Druck im Innenraum 44 und das Druckregulierventil 39 wird dadurch geöffnet. Über die Druckwasserleitung 24 strömt nun Wasser in den Innenraum 44 und durch den Strömungsspalt 46 in den Raum 17, sodass sich im Innenraum 17 langsam wieder ein Druck aufbaut. Gleichzeitig gelangt Wasser über den Durchgang 43 in die Entlüftungsleitung 18 und strömt nach unten in den Behälter 2. Dieses Wasser gelangt über die Öffnung 38 in die hier nicht gezeigte Toilettenschüssel und füllt hierbei den Siphon wieder auf. Das Nachfüllen des Siphons ist dann erforderlich, wenn dieser bei einer Spülung geleert wird und dadurch nachgefüllt werden muss.Is all rinse water 14 escaped from the container 2, so prevails in the container 2 no overpressure. The water in the interior 17 is not used as rinsing water and remains in this interior space 17. As a result, the pressure in the interior 44 decreases and the pressure regulating valve 39 is opened thereby. Via the pressurized water line 24, water now flows into the interior 44 and through the flow gap 46 into the space 17, so that a pressure builds up again slowly in the interior 17. At the same time water passes through the passage 43 in the vent line 18 and flows down into the container 2. This water passes through the opening 38 in the toilet bowl, not shown here, and this fills the siphon again. The refilling of the siphon is required if it is emptied during a flushing and must be refilled.

Ist der Druck im Innenraum 17 so gross, dass die Reibungskraft der Lippendichtung 30 am Führungsrohr 9 überwunden werden kann, so bewegt sich der Verschlusskörper 7 nach unten, bis die Ablaufarmatur 6 geschlossen ist. Das Druckregulierventil 45 ist weiterhin offen, sodass auch bei geschlossener Ablaufgarnitur 6 Wasser in den Behälter 2 strömt und diesen füllt. Da das Entlüftungsventil 11 nun geschlossen ist, kann die Luft im Druckraum 15 nicht entweichen und wird vom steigenden Wasser komprimiert. Befindet sich die Wasseroberfläche 42 auf der Höhe gemäss Figur 1, so ist der Druck im Spülwasser 14 so gross, dass das Entlüftungsventil 19 schliesst. Die Zufuhr von Wasser in den Behälter 2 wird damit beendet. Durch den Druckanstieg im Innenraum 14 schliesst nun auch das Druckregulierventil 45. Die Spülvorrichtung 1 hat damit wieder die Ruhestellung gemäss Figur 1 erreicht und ist für einen weiteren Spülvorgang bereit.If the pressure in the interior 17 is so great that the frictional force of the lip seal 30 on the guide tube 9 can be overcome, the closure body 7 moves downwards until the drain fitting 6 is closed. The pressure regulating valve 45 is still open, so that even with the drain set 6 water flows into the container 2 and fills it. Since the vent valve 11 is now closed, the air in the pressure chamber 15 can not escape and is compressed by the rising water. If the water surface 42 is at the level according to FIG. 1, then the pressure in the rinsing water 14 is so great that the venting valve 19 closes. The supply of water into the container 2 is thus terminated. Due to the increase in pressure in the interior 14 now also closes the pressure regulating valve 45. The flushing device 1 has thus again reached the rest position according to Figure 1 and is ready for another flushing.

Die anhand der Figur 1 erläuterte Spülung ist eine Vollspülung, d.h. es wird im Wesentlichen das gesamte im Behälter 2 vorliegende Wasser 14 zur Spülung verwendet. Ausgenommen ist hierbei das Wasser im Innenraum 44 und im Innenraum 17 des Kolbens 16. Wird für einen Spülvorgang lediglich ein Teil des vorliegenden Spülwassers 14 benötigt, so wird die Taste B betätigt und damit eine Teilspülung ausgelöst. Über die Steuervorrichtung 55 wird wie oben erläutert der Schieber 11a bewegt und damit eine Spülung ausgelöst. Gemäss Figur 1 wird mit einem Niveausensor 57 über die Steuervorrichtung 55 der Verschlusskörper 7 vorzeitig in die Schliessstellung gebracht. Hierzu wird durch die Steuervorrichtung 55 aufgrund eines Signals des Niveausensors 57 der Verriegelungsschieber 32 gemäss Figur 3 in Richtung des Pfeils 51 verschoben. Die Taste B kann aber auch über eine mechanische Steuervorrichtung mit dem Verriegelungsschieber verbunden sein oder über eine Drucksteuerung das Entriegeln auslösen. Hierbei wird der kolbenförmige Teil 50 entriegelt. Dieser Teil 50 liegt mit dem nach unten vorragenden Abschnitt 35 bei geöffneter Ablaufarmatur 6 an einer oberen Wandung 52 des Ventilkörpers 7 an, wie die Figur 2 zeigt. Nach der Entriegelung wird der kolbenförmige Teil 50 unter der Wirkung der gespannten Feder 49 nach unten bewegt. Durch die Kraft der Feder 49 bewegt sich gleichzeitig der Verschlusskörper 7 nach unten. Die Kraft der Feder 49 ist nun so ausgelegt, dass die Reibungskraft der Lippendichtung 30 am Führungsrohr 34 überwunden werden kann. Der Verschlusskörper 7 wird durch den kolbenförmigen Teil 50 gemäss Figur 3 in Richtung des Pfeils 58 nach unten bewegt, bis die Ablaufgarnitur geschlossen ist. Die Figur 1 zeigt den Verschlusskörper 7 in der unteren Stellung, in welcher die Ablaufarmatur 6 geschlossen ist. Der Spülvorgang ist damit beendet.The rinsing explained with reference to FIG. 1 is a full rinse, that is, substantially all of it is present in the container 2 Water 14 used for rinsing. Excluded here is the water in the interior 44 and in the interior 17 of the piston 16. If only a portion of the present rinse water 14 is required for a rinse, the button B is actuated, thus triggering a partial rinse. As explained above, the slide 11a is moved via the control device 55, thus triggering a flush. According to FIG. 1, the closure body 7 is prematurely brought into the closed position with the aid of a level sensor 57 via the control device 55. For this purpose, the locking slide 32 according to FIG. 3 is displaced in the direction of the arrow 51 by the control device 55 on the basis of a signal of the level sensor 57. The button B can also be connected via a mechanical control device with the locking slide or trigger the unlocking via a pressure control. In this case, the piston-shaped part 50 is unlocked. This part 50 rests with the downwardly projecting portion 35 with the drain fitting 6 open at an upper wall 52 of the valve body 7, as FIG. 2 shows. After unlocking the piston-shaped part 50 is moved under the action of the tensioned spring 49 down. Due to the force of the spring 49, the closure body 7 simultaneously moves downwards. The force of the spring 49 is now designed so that the frictional force of the lip seal 30 on the guide tube 34 can be overcome. The closure body 7 is moved by the piston-shaped part 50 according to Figure 3 in the direction of the arrow 58 down until the drain fitting is closed. FIG. 1 shows the closure body 7 in the lower position, in which the drain fitting 6 is closed. The flushing process is over.

Durch die vorzeitige Schliessung der Ablaufarmatur 6 verbleibt im Behälter 2 ein Teil des Spülwassers 14. Infolge der Teilspülung ist der Druck im Behälter 2 so weit gesunken, dass sich das Entlüftungsventil 19 öffnet. Durch den Druckabfall im Innenraum 44 öffnet ebenfalls das Druckregulierventil 45 und entsprechend wird der Behälter 2 wieder durch einströmendes Wasser gefüllt. Dadurch wird der oben erwähnte Füllvorgang ausgelöst und führt wieder zu dem in Figur 1 gezeigten Ruhezustand. Die Spülvorrichtung 1 ist nunmehr wieder für eine Spülung, eine Vollspülung oder Teilspülung bereit.Due to the premature closure of the drain fitting 6 remains in the container 2, a portion of the rinse water 14. As a result of partial rinse the pressure in the container 2 has dropped so far that the vent valve 19 opens. Due to the pressure drop in the interior 44 also opens the pressure regulating valve 45 and accordingly the container 2 is filled again by inflowing water. As a result, the above-mentioned filling process is triggered and leads again to the rest state shown in Figure 1. The flushing device 1 is now ready for a flush, a full flush or partial flush.

Die Figur 4 zeigt eine Toilettenanlage 100 mit einer Spülvorrichtung 101 und einer Toilettenschüssel 109. Die Spülvorrichtung 101 besitzt einen Behälter 116, in dem in einer Kammer 115 Spülwasser 117 mit einem Kolben 102 unter Druck gehalten ist. Eine Ablaufarmatur 104 besitzt einen Verschlusskörper 105, welcher in Figur 4 eine Auslauföffnung 118 verschliesst. Der Kolben 102 ist in der Figur 4 in einer oberen Stellung und wird von einer gespannten Feder 103 beaufschlagt. Die Feder 103 entspricht der oben erwähnten Luft in der Kammer 15. Die Feder 103 bildet hier somit ebenfalls ein Mittel, um das Spülwasser 107 unter Druck aus dem Raum 115 abzugeben. Wird der Verschlusskörper 105 angehoben, so strömt das Spülwasser 117 über einen Stutzen 106 in eine Leitung 107 und in eine Leitung 108. Die Leitung 108 führt über eine Verteilkammer 110 der Klosettschüssel 109 in einen Spülrand 111 und schliesslich in Richtung der Pfeile 120 entlang einer Innenseite 119 der Klosettschüssel 109 in einen Siphon 113. Das durch die Leitung 107 hindurchströmende Wasser gelangt zu einer Düse 112, die in an sich bekannter Weise einen Wasserstrahl in Richtung des Pfeils 114 in Siphonwasser 121 abgibt. Durch diesen Wasserstrahl wird beim Spülvorgang das Siphonwasser 121 beschleunigt, was das Ausschwemmen wirksamer macht. Das durch den Spülkanal 111 in die Klosettschüssel 109 einströmende Wasser reinigt die Innenseite 119 von Rückständen.FIG. 4 shows a toilet installation 100 with a flushing device 101 and a toilet bowl 109. The flushing device 101 has a container 116 in which flushing water 117 with a piston 102 is held under pressure in a chamber 115. A drain fitting 104 has a closure body 105, which closes an outlet opening 118 in FIG. The piston 102 is in an upper position in FIG. 4 and is acted upon by a tensioned spring 103. The spring 103 corresponds to the above-mentioned air in the chamber 15. The spring 103 here thus also forms a means for discharging the rinsing water 107 under pressure from the space 115. If the closure body 105 is raised, then the rinse water 117 flows via a connection 106 into a line 107 and into a line 108. The line 108 leads via a distribution chamber 110 of the toilet bowl 109 into a rinsing edge 111 and finally in the direction of the arrows 120 along an inner side 119 of the toilet bowl 109 in a siphon 113. The water flowing through the line 107 water passes to a nozzle 112, which emits in a conventional manner a water jet in the direction of arrow 114 in siphon water 121. By this water jet, the siphon water 121 is accelerated during the flushing process, which makes flushing more effective. The water flowing through the flushing channel 111 into the toilet bowl 109 cleans the inside 119 of residues.

Auch bei der Toilettenanlage 100 ist eine Teilspülung vorgesehen. Bei einer Teilspülung fährt der Kolben 102 beispielsweise lediglich bis zur gestrichelten Linie 122. Dies wird durch eine vorzeitige Schliessung der Ablaufarmatur 104 erreicht. Eine solche vorzeitige Schliessung ist grundsätzlich wie oben erläutert möglich. Das vorzeitige Schliessen kann beispielsweise mit einem hier lediglich angedeuteten Teil 123 erfolgen, welcher dem kolbenförmigen Teil 50 der Figuren 1 bis 3 entspricht. Zum vorzeitigen Schliessen wird der Verschlusskörper 105 mittels einer Feder 124 nach unten bewegt. Die Unterbrechung kann auch hier automatisch über eine Steuervorrichtung 55 erfolgen, die beispielsweise von einem Niveausensor 57 ein Signal erhält. Aufgrund der besonders wirksamen Schwemmung mit Hilfe der Düse 112 ist eine Spülung mit besonders wenig Spülwasser möglich. Eine Vollspülung ist mit wesentlich weniger als 6 1 Spülwasser und eine Teilspülung mit weniger als 4 1 Spülwasser möglich. Auch hier wird Spülwasser besonders durch die Möglichkeit einer Teilspülung gespart. Die Spülvorrichtung 101 kann hier grundsätzlich auch durch die Spülvorrichtung 1 gemäss den Figuren 1 bis 3 ersetzt sein.Also in the toilet system 100, a partial flush is provided. For example, in the case of a partial flush, the piston 102 moves only as far as the dashed line 122. This is achieved by a premature closure of the drain fitting 104. Such premature closure is basically possible as explained above. The premature closing can be done, for example, with a part 123 only indicated here, which corresponds to the piston-shaped part 50 of FIGS. 1 to 3. For premature closing of the closure body 105 is moved by a spring 124 down. The interruption can also take place automatically via a control device 55, which receives a signal from a level sensor 57, for example. Due to the particularly effective alluviation with the help of the nozzle 112, a rinse with very little rinsing water is possible. A full rinse is possible with significantly less than 6 1 rinse water and a partial rinse with less than 4 1 rinse water. Again, rinse water is saved especially by the possibility of partial flushing. In principle, the flushing device 101 can also be replaced by the flushing device 1 according to FIGS. 1 to 3.

Die in Figur 5 gezeigte Toilettenanlage 200 weist ebenfalls eine Spülvorrichtung 201 sowie eine Toilettenschüssel 212 auf. Das durch einen Stutzen 209 abgegebene Spülwasser wird ebenfalls auf zwei Leitungen 210 und 211 aufgeteilt. Das durch die Leitung 211 gelangende Wasser dient wie oben erläutert zum Ausspülen eines Siphons 213, während das durch die Leitung 210 oben in die Toilettenschüssel 212 einströmende Wasser zur Reinigung der Innenseite der Toilettenschüssel 212 dient.The toilet installation 200 shown in FIG. 5 also has a flushing device 201 and a toilet bowl 212. The rinse water discharged through a nozzle 209 is also split into two lines 210 and 211. The water passing through the conduit 211 serves to rinse out a siphon 213 as explained above, while the water flowing in through the conduit 210 into the toilet bowl 212 above serves to clean the inside of the toilet bowl 212.

Die Spülvorrichtung 201 unterscheidet sich von der Spülvorrichtung 101 insbesondere dadurch, dass hier zwei Kolben 202 und 203 vorgesehen sind, die jeweils unabhängig von einander auslösbar und jeweils von einer Feder 206 bzw. 207 belastet sind. Die Bewegung der Kolben 202 und 203 nach unten wird jeweils durch einen Anschlag 208 begrenzt. In der Figur 5 sind die beiden Kolben 202 und 203 jeweils in der oberen Stellung arretiert und von einer gespannten Feder 206 bzw. 207 belastet. Wird der Kolben 202 nach unten in die gestrichelt gezeigte Position bewegt, so wird das in einer Kammer 204 befindliche Spülwasser über den Stutzen 209 in die Leitungen 210 und 211 ausgestossen. Vom vorhandenen Spülwasser wird somit lediglich eine Teilmenge abgegeben. Dies ist auch dann der Fall, wenn der Kolben 203 nach unten bewegt wird. Die beiden Kammern 204 und 205 können gleich oder unterschiedlich sein. Sind sie unterschiedlich im Volumen, so können zwei verschiedene Teilmengen abgegeben werden. Beispielsweise kann die Kammer 204 2 1 Spülwasser und die Kammer 205 3 1 Spülwasser enthalten. Es sind dann somit Teilspülungen wahlweise mit 2 1 oder 3 1 Spülwasser möglich. Für eine Vollspülung werden gleichzeitig beide Kolben 202 und 203 nach unten bewegt. In diesem Fall wird somit das Spülwasser der Kammer 204 als auch das Spülwasser der Kammer 205 ausgestossen. Die Federn 206 und 207 können auch durch ein Luftpolster ersetzt sein. Die Auslösung erfolgt hier ebenfalls mit zwei hier nicht gezeigten Tasten A und B. Es können hier auch drei Tasten vorhanden sein, wenn wie erläutert zwei unterschiedliche Teilspülungen vorgesehen sind.The rinsing device 201 differs from the rinsing device 101 in particular in that here two pistons 202 and 203 are provided, each of which can be triggered independently of one another and each loaded by a spring 206 and 207, respectively. The movement of the pistons 202 and 203 downwards is limited by a stop 208. In FIG. 5, the two pistons 202 and 203 are each locked in the upper position and loaded by a tensioned spring 206 or 207. When the piston 202 is moved downwardly into the position shown in dashed lines, the rinse water contained in a chamber 204 is expelled via the nozzle 209 into the lines 210 and 211. From existing rinse water thus only a subset is delivered. This is also the case when the piston 203 is moved down. The two chambers 204 and 205 may be the same or different. If they are different in volume, two different subsets can be dispensed. For example, the chamber 204 2 1 rinse water and the chamber 205 3 1 rinse water included. There are then partial rinses optionally with 2 1 or 3 1 rinse water possible. For a full flush both pistons 202 and 203 are simultaneously moved down. In this case, therefore, the rinsing water of the chamber 204 and the rinsing water of the chamber 205 are ejected. The springs 206 and 207 may also be replaced by an air cushion. The triggering takes place here also with two keys A and B, not shown here. There may also be three keys if, as explained, two different partial flushes are provided.

Die Figur 6 zeigt eine Toilettenanlage 300, die eine Spülvorrichtung 301 sowie eine Toilettenanlage 309 aufweist. Die Spülvorrichtung 301 besitzt einen Behälter 312, der zwei Kammern 305 und 306 aufweist, in denen jeweils ein federbelasteter Kolben 303 bzw. 304 verschieblich gelagert ist. Die Kammer 305 ist über ein Ventil 313 mit einer Leitung 307 verbunden, die in einen Spülkanal 310 führt. Die Kammer 306 hingegen führt über ein weiteres Ventil 314 über eine Leitung 308 zu einer Düse 311. Die beiden Kammern 305 und 306 sind in der Ruhestellung mit Wasser gefüllt, das durch den Kolben 304 bzw. 304 unter Druck gehalten ist. Der Druck kann durch gespannte Federn 302 bzw. 315 oder durch ein Luftpolster ausgeübt werden. Wird bei einer Spülauslösung der Kolben 303 nach unten bewegt, wobei hier selbstverständlich gleichzeitig das Ventil 313 geöffnet wird, so gelangt aus der Kammer 305 Spülwasser durch die Leitung 307 in den Spülkanal 310. Der Kolben 304 verbleibt hierbei in der Ruhestellung und ebenfalls verbleibt das Spülwasser der Kammer 306 im Behälter 301. Eine solche Spülung ist somit eine Teilspülung, bei welcher lediglich über den Spülrand 310 Spülwasser in die Toilettenschüssel 309 gelangt.FIG. 6 shows a toilet installation 300 which has a flushing device 301 and a toilet installation 309. The flushing device 301 has a container 312, which has two chambers 305 and 306, in each of which a spring-loaded piston 303 and 304 is displaceably mounted. The chamber 305 is connected via a valve 313 to a line 307, which leads into a flushing passage 310. The chamber 306, however, leads via a further valve 314 via a line 308 to a nozzle 311. The two chambers 305 and 306 are in the rest position with water filled, which is held by the piston 304 and 304 under pressure. The pressure can be exerted by tensioned springs 302 and 315 or by an air cushion. If the piston 303 is moved downwards during a rinsing release, the valve 313 being opened at the same time, then rinsing water passes from the chamber 305 through the line 307 into the rinsing channel 310. The piston 304 remains in the rest position and the rinsing water also remains The chamber 306 in the container 301. Such a flush is thus a partial flush, in which only via the flushing edge 310 rinse water enters the toilet bowl 309.

Für eine Vollspülung werden gleichzeitig die beiden Kolben 303 und 304 nach unten bewegt. Das Wasser aus der Kammer 305 gelangt wie oben erwähnt über die Leitung 307 in den Spülkanal 310. Gleichzeitig gelangt das Spülwasser der Kammer 306 über die Leitung 308 zur Düse 311 und bewirkt wie oben erläutert ein Ausschwemmen des Siphons. Vorteilhaft ist hierbei, dass das Spülwasser separat unterschiedlich unter Druck setzbar ist.For a full flush simultaneously the two pistons 303 and 304 are moved down. The water from the chamber 305 passes as mentioned above via the line 307 in the flushing passage 310. At the same time the flushing water of the chamber 306 passes via the line 308 to the nozzle 311 and causes as explained above, a flushing of the siphon. It is advantageous here that the rinse water can be placed separately under different pressure.

Die Figuren 7a bis 7c zeigen eine Spülvorrichtung 400, die einen Behälter 401 besitzt, in dem ein Kolben 402 begrenzt vertikal verschiebbar ist. An einem unteren Ende des Behälters 401 ist ein Ventil 409 angeordnet, das mit einem horizontalen Ausgang 411 und/oder einem vertikal nach unten gerichteten Ausgang 410 verbunden ist. Der horizontale Ausgang 411 führt zu einem hier nicht gezeigten Spülkanal und der Ausgang 410 zu einer Spüldüse, welche beispielsweise der in Figur 6 gezeigten Spüldüse 311 entspricht. Die Bewegung des Kolbens 402 ist durch eine Schulter 408 begrenzt. Am oberen Ende des Kolbens 402 ist ein aus dem Behälter 401 nach oben vorragender Kopf 404 befestigt, der mit einem schwenkbaren Rasthebel 405 fixiert ist. Der Kolben 402 ist zudem gemäss Figur 7a in der Ruhestellung von einer gespannten Feder 403 belastet. Im Behälter 401 befindet sich bei geschlossenem Ventil 409 eine vorbestimmte Menge an Spülwasser 407. Zwischen diesem Spülwasser 407 und dem Kolben 402 befindet sich ein Zwischenraum mit Luft 406, die einen Überdruck aufweist. Der Überdruck wird beim Nachfüllen des Behälters 401 erzeugt, wie dies oben anhand der Figur 1 erläutert wurde. Der Überdruck beträgt beispielsweise 2 bar.FIGS. 7a to 7c show a flushing device 400 which has a container 401 in which a piston 402 can be displaced vertically in a limited manner. At a lower end of the container 401, a valve 409 is arranged, which is connected to a horizontal outlet 411 and / or a vertically downward exit 410. The horizontal output 411 leads to a flushing channel, not shown here, and the outlet 410 to a flushing nozzle which, for example, corresponds to the flushing nozzle 311 shown in FIG. The movement of the piston 402 is limited by a shoulder 408. At the upper end of the piston 402 a from the container 401 upwardly projecting head 404 is fixed, which is fixed with a pivotable locking lever 405. The piston 402 is also according to Figure 7a in the rest position of a loaded spring 403 loaded. In the container 401 is located at a closed valve 409 a predetermined amount of rinse water 407. Between this rinse water 407 and the piston 402 is a gap with air 406, which has an overpressure. The overpressure is generated during refilling of the container 401, as has been explained above with reference to FIG. The overpressure is for example 2 bar.

Die Arbeitsweise der Spülvorrichtung 400 wird anhand der Figuren 7a bis 7c nachfolgend näher erläutert.The operation of the flushing device 400 will be explained in more detail below with reference to FIGS. 7a to 7c.

Die Figur 7a zeigt die Spülvorrichtung 400 in der Ruhestellung. Sie hier somit mit Spülwasser 407 gefüllt und für eine Spülung bereit. Zum Auslösen einer Teilspülung wird das Ventil 409 geöffnet. Die Luft 406 kann sich damit entspannen und stösst einen Teil des Spülwassers 407 aus dem Behälter 401 aus. Ein Teil des Wassers gelangt zum Spülkanal und ein anderer Teil des Wassers zur Düse. Möglich ist hier auch eine Variante, bei welcher lediglich ein Durchgang zum Stutzen 411 geöffnet wird. Das Spülwasser gelangt in diesem Fall lediglich zum Spülkanal. Hat sich die Luft 406 entspannt, so wird das Ventil 409 geschlossen. Das Schliessen des Ventils 409 erfolgt automatisch, beispielsweise über einen Drucksensor. Die Figur 7b zeigt die Spülvorrichtung 400 nach einer Teilspülung. Das Ventil 409 ist hier somit wieder geschlossen. Der Druckabfall bewirkt wieder ein Nachfüllen des Behälters 401 mit Wasser und somit wieder den Aufbau eines Drucks in der Luft 406. Hierbei wird wieder der in Figur 7a gezeigte Zustand gezeigt.FIG. 7 a shows the flushing device 400 in the rest position. You here thus filled with rinse water 407 and ready for a rinse. To trigger a partial flush valve 409 is opened. The air 406 can relax with it and ejects a portion of the rinse water 407 from the container 401. Part of the water reaches the flushing channel and another part of the water reaches the nozzle. Also possible here is a variant in which only one passage to the neck 411 is opened. The rinse water in this case only reaches the flushing channel. If the air 406 has relaxed, the valve 409 is closed. The closing of the valve 409 takes place automatically, for example via a pressure sensor. FIG. 7b shows the flushing device 400 after a partial flushing. The valve 409 is thus closed again here. The pressure drop again causes a refilling of the container 401 with water and thus again the build-up of a pressure in the air 406. Here again the state shown in Figure 7a is shown.

Soll eine Vollspülung ausgelöst werden, so wird wie oben erläutert das Ventil 401 geöffnet. Gleichzeitig wird hierdurch der Kolben 402 entriegelt, indem der Riegel 405 in die in Figur 7c gezeigte Position verschwenkt wird. Ist der Kolben 402 entriegelt, so kann sich die Feder 403 entspannen und den Kolben 402 nach unten in die in Figur 7c gezeigte Position bewegen. Der sich nach unten bewegende Kolben 402 bewirkt eine im Wesentlichen vollständige Verdrängung des Spülwassers 407 sowie die Verlagerung der Luft 406 in den unteren Bereich des Behälters 401, wie dies in Figur 7c gezeigt ist. Nach der Spülung wird das Ventil 409 wieder geschlossen und durch einströmendes Wasser wird einerseits die Luft 406 komprimiert und andererseits die Feder 403 gespannt, bis der Kolben 402 am Kopf 404 wieder verriegelt ist. Die Spülvorrichtung 400 ist nun wieder für eine Teil- oder Vollspülung bereit. Auch in diesem Fall kann die Feder 403 grundsätzlich durch ein Luftpolster oder ein anderes Energiespeichermittel ersetzt sein.If a full flush is triggered, as explained above, the valve 401 is opened. At the same time the piston 402 is thereby unlocked by the latch 405 is pivoted to the position shown in Figure 7c. When the piston 402 is unlocked, so spring 403 can relax and move piston 402 down to the position shown in FIG. 7c. The downwardly moving piston 402 causes substantially complete displacement of the flushing water 407 and the displacement of the air 406 into the lower portion of the container 401, as shown in Figure 7c. After flushing, the valve 409 is closed again and by inflowing water on the one hand, the air 406 is compressed and on the other hand, the spring 403 stretched until the piston 402 is locked on the head 404 again. The flushing device 400 is now ready for a partial or full flush. Also in this case, the spring 403 may be basically replaced by an air cushion or other energy storage means.
