The locking pressure of the pressure reduction valve can be altered using an adjustable ring (17), preferably gradually. The ring can be reached from the exterior through a window in the housing.

Description

Die Erfindung betrifft einen Druckspülkasten für ein Wasserklosett nach dem Oberbegriff des Anspruchs 1.The invention relates to a pressure cistern for a water closet according to the preamble of claim 1.

Die US-A-5,553,333 offenbart einen gattungsgemässen Druckspülkasten. Das Druckreduzierventil weist eine Druckfeder auf, die durch Drehen einer Hülse bezüglich ihrer Vorspannung veränderbar ist. Je nach Vorspannung der Druckfeder wird das Druckreduzierventil beim Füllen des Spülkastens früher oder später geschlossen. Die Druckfeder und die Hülse sind an einer oberen Wandung des Spülkastens und der Kolben am oberen Ende eines Einlaufrohres. Aufgrund dieser getrennten Anordnung dürfte es schwierig sein, eine exakte und gleichbleibende Einstellung zu erreichen.The US-A-5,553,333 discloses a generic pressure cistern. The pressure reducing valve has a compression spring, which is variable by turning a sleeve with respect to its bias. Depending on the bias of the spring, the pressure reducing valve is closed when filling the cistern sooner or later. The compression spring and the sleeve are at an upper wall of the cistern and the piston at the upper end of an inlet pipe. Due to this separate arrangement, it should be difficult to achieve an exact and consistent adjustment.

Ein weiterer Druckspülkasten, dessen Fülldruck durch Austauschen der Druckfelder justiert wird ist im Stand der Technik beispielsweise aus der WO 98/39522 bekannt geworden. Druckspülkästen dieser Art haben den Vorteil, dass sie bei vergleichsweise kleinem Wasserverbrauch eine wirksame Reinigung des Klosettbeckens ermöglichen. Der Drucktank wird mit einer an den Druckspülkasten angeschlossenen Wasserleitung mit Spülwasser gefüllt. Hierbei wird im Drucktank vorhandene Luft komprimiert. Wird das Auslaufventil geöffnet, so wird Spülwasser unter Entspannung der Luft in die Klosettschüssel abgegeben. Das Auslaufventil ist als Kolben ausgebildet und verschliesst das Auslaufventil, wenn das Spülwasser ausgeflossen ist.Another Druckspülkasten whose filling pressure is adjusted by replacing the pressure fields in the art, for example, from WO 98/39522 known. Pressure flush boxes of this type have the advantage that they allow for relatively small water consumption effective cleaning of the toilet bowl. The pressure tank is filled with flushing water with a water pipe connected to the pressurized cistern. In this case, existing air is compressed in the pressure tank. If the outlet valve is opened, rinse water is released into the toilet bowl while the air is released. The outlet valve is designed as a piston and closes the outlet valve when the rinse water has flowed out.

Eine weitere Komponente des Druckspülkastens ist der so genannte Systemtrenner, der verhindert, dass bei einem Unterdruck in der Wasserleitung Spülwasser aus dem Drucktank in die Versorgungsleitung gesogen wird. Ein solcher Systemtrenner (vacuum breaker) ist in der genannten WO 98/39522 offenbart.Another component of the pressurized cistern is the so-called system separator, which prevents rinsing water from being sucked from the pressure tank into the supply line when there is a negative pressure in the water line. Such a system breaker (vacuum breaker) is mentioned in the WO 98/39522 disclosed.

Damit nach dem Füllen des Drucktankes in diesem ein vorbestimmter Druck nicht überschritten wird, ist ein Druckreduzierventil vorgesehen, welches den maximalen Druck begrenzt. Dieses Druckreduzierventil weist beim aus WO 98/39522 bekannten Druckspülkasten einen Kolben auf, der dem Druck im Drucktank ausgesetzt ist und gegen die rückwirkende Kraft einer Feder die Mündung einer Düse schliesst. Sinkt bei einer Spülung der Druck im Drucktank, so verschiebt sich er Kolben des Druckreduzierventils aufgrund einer Druckdifferenz am Kolben und dadurch wird das Eingangsventil geöffnet. Durch die freigegebene Mündung der Düse strömt Wasser in den Drucktank. Ist ein vorbestimmter Druck im Drucktank erreicht, so schliesst das Druckreduzierventil. Durch Austausch der genannten Feder kann der vorgesehene maximale Druck im Drucktank geändert werden. Eine stärkere Feder ergibt einen höheren Druck und eine schwächere Feder einen niedrigeren Druck. Ein solcher Austausch der Feder ist aber vergleichsweise aufwändig.So that after filling the pressure tank in this a predetermined pressure is not exceeded, a pressure reducing valve is provided which limits the maximum pressure. This pressure reducing valve has the off WO 98/39522 known Druckspülkasten on a piston which is exposed to the pressure in the pressure tank and closes against the retroactive force of a spring, the mouth of a nozzle. If the pressure in the pressure tank drops during a purge, it displaces the piston of the pressure reducing valve due to a pressure difference on the piston and thus the inlet valve is opened. Through the released mouth of the nozzle, water flows into the pressure tank. If a predetermined pressure in the pressure tank is reached, the pressure reducing valve closes. By replacing the said spring, the intended maximum pressure in the pressure tank can be changed. A stronger spring gives a higher pressure and a weaker spring a lower pressure. Such an exchange of the spring is comparatively expensive.

Der Erfindung liegt die Aufgabe zugrunde, einen Druckspülkasten der genannten Art zu schaffen, der eine einfachere Umstellung auf einen anderen maximalen Druck im Drucktank ermöglicht.The invention has for its object to provide a pressure cistern of the type mentioned, which allows easier transition to another maximum pressure in the pressure tank.

Die Aufgabe ist bei einem gattungsgemässen Druckspülkasten gemäss Anspruch 1 gelöst.The object is achieved in a generic pressure cistern according to claim 1.

Dabei ist die Schliesskraft der Gegendruckfeder des Druckreduzierventils einstellbar. Dies ist dann konstruktiv besonders einfach und auch bedienungsfreundlich, wenn die Druckfeder mit einem Einstellring einstellbar ist, wobei der Einstellring für die Feder ein Gegenlager bildet.The closing force of the counterpressure spring of the pressure reducing valve is adjustable. This is then structurally particularly simple and easy to use, when the compression spring is adjustable with an adjusting ring, wherein the adjusting ring for the spring forms an abutment.

Vorzugsweise ist das Ventilgehäuse des Eingangsventils seitlich offen ausgebildet, so dass der Einstellring von aussen fassbar und verstellbar ist. Vorzugsweise sind stufenförmige Ausnehmungen am Ventilgehäuse angeordnet, die jeweils einer Einstellposition des Einstellringes entsprechen. Beispielsweise entspricht eine solche Stufe einem Innendruck von 1,5 bar, eine zweite Ausnehmung einem Innendruck von 2 bar und eine weitere Ausnehmung einem Innendruck von 2,5 bar.Preferably, the valve housing of the input valve is designed to be open at the side so that the adjustment ring can be grasped and adjusted from the outside. Preferably, stepped recesses are arranged on the valve housing, each corresponding to a setting position of the adjusting ring. For example, such a level corresponds to an internal pressure of 1.5 bar, a second recess to an internal pressure of 2 bar and a further recess to an internal pressure of 2.5 bar.

Nach einer Weiterbildung der Erfindung weist der Einstellring Haltenocken zu seiner stufenförmigen Verstellung auf. Diese Haltenocken sirid von aussen zugänglich und jeweils in einer entsprechenden Ausnehmung des Ventilgehäuses fixiert. Denkbar ist auch eine Ausführung, nach welcher die Einstellmittel bzw. der Einstellring stufenlos verstellbar ist.According to a development of the invention, the adjusting ring retaining cam to its step-like adjustment. These retaining cams sirid accessible from the outside and fixed in each case in a corresponding recess of the valve housing. Also conceivable is an embodiment, according to which the adjusting means or the adjusting ring is infinitely adjustable.

Ein besonders einfacher und kostengünstiger Aufbau ergibt sich durch die Anordnung des Druckreduzierventils am Ausgang eines Systemtrenners. Dabei ist der genannte Einstellring am Umfang des Düsenkörpers des Druckreduzierventil axial verstellbar angeordnet.A particularly simple and inexpensive construction results from the arrangement of the pressure reducing valve at the output of a system separator. In this case, said adjusting ring is arranged axially adjustable on the circumference of the nozzle body of the pressure reducing valve.

Weitere vorteilhafte Merkmale ergeben sich aus den abhängigen Patentansprüchen, der nachfolgenden Beschreibung sowie der Zeichnung.Further advantageous features emerge from the dependent claims, the following description and the drawings.

Der Druckspülkasten 1 besitzt einen in Figur 1 lediglich abschnittweise gezeigten Drucktank 2, der einen Druckraum 3 besitzt, welcher über ein Druckreduzierventil 27 mit Spülwasser gefüllt wird. Für die Zufuhr des Spülwassers wird der Druckspülkasten 1 an einem Anschlussstutzen 5 eines Systemtrenners 25 an eine hier nicht gezeigte Druckwasserleitung angeschlossen. Der an sich bekannte Systemtrenner 25 ist aus Sicherheitsgründen vorgesehen und verhindert, dass bei einem Unterdruck Wasser aus dem Drucktank 2 in die Versorgungsleitung gelangen kann. Solche Systemtrenner sind in vielen Ländern Vorschrift und an sich bekannt.The pressure cistern 1 has a in Figure 1 only partially shown pressure tank 2, which has a pressure chamber 3, which via a pressure reducing valve 27 with Rinse water is filled. For the supply of rinsing water, the pressure cistern 1 is connected to a connecting piece 5 of a system separator 25 to a pressurized water line, not shown here. The known system separator 25 is provided for safety reasons and prevents water from the pressure tank 2 can get into the supply line at a negative pressure. Such system separator are in many countries regulation and known per se.

Der Systemtrenner 25 weist ein Gehäuse 6 auf, das an einem unteren Ende ein sich horizontal erstreckenden Düsenkörper 21 bildet. Im Düsenkörper 21 verläuft ebenfalls horizontal ein Kanal 15 mit einer Mündung 4.The system separator 25 has a housing 6 which forms a horizontally extending nozzle body 21 at a lower end. In the nozzle body 21 also runs horizontally a channel 15 with an orifice. 4

Der Düsenkörper 21 ist Teil eines Druckreduzierventils 27, das am Ausgang des Systemtrenners 25 angeordnet ist. Das Druckreduzierventil 27 besitzt ein kappenförmiges Gehäuse 7, das in eine Öffnung 31 des Gehäuses 6 eingesetzt ist. Die Verbindung des Gehäuses 7 zum Gehäuse 6 kann beispielsweise als Bajonett- oder Schraubverbindung ausgebildet sein. Das Gehäuse 7 besitzt an einem Ende eine Öffnung 8, die in ein Rohr 30 und schliesslich in den Drucktank 2 führt.The nozzle body 21 is part of a pressure reducing valve 27, which is arranged at the output of the system separator 25. The pressure reducing valve 27 has a cap-shaped housing 7 which is inserted into an opening 31 of the housing 6. The connection of the housing 7 to the housing 6 may be formed for example as a bayonet or screw connection. The housing 7 has at one end an opening 8, which leads into a pipe 30 and finally into the pressure tank 2.

Das vordere Ende des Düsenkörpers 21 bildet einen Ventilsitz 14, der mit einem Verschlusskörper 12 zusammenarbeitet. Dieser Verschlusskörper 12 ist vorzugsweise als Kugel ausgebildet und in einem Strömungskanal 13 eines Kolbens 9 gelagert. Dieser Kolben 9 besitzt einen Führungsteil 18, der mit einer Dichtung 29 verschiebbar gegen das Gehäuse 7 abgedichtet ist. Der Führungsteil 18 ist zudem mit einer weiteren Dichtung 28 gegenüber dem Düsenkörper 21 ebenfalls verschieblich abgedichtet. Wie ersichtlich, befindet sich die Dichtung 28 unmittelbar hinter dem Ventilsitz 14. Der Kolben 9 ist somit begrenzbar in der Richtung des Kanals 15 verschiebbar geführt.The front end of the nozzle body 21 forms a valve seat 14, which cooperates with a closure body 12. This closure body 12 is preferably designed as a ball and mounted in a flow channel 13 of a piston 9. This piston 9 has a guide member 18 which is sealed with a seal 29 slidably against the housing 7. The guide member 18 is also also sealed with a further seal 28 relative to the nozzle body 21 slidably. As can be seen, the seal 28 is located immediately behind the valve seat 14. The piston 9 is thus limited in the direction of the channel 15 slidably guided.

In den Führungsteil 18 ist ein Einsatz 32 eingesetzt, in den ein weiterer Verschlusskörper 11 gelagert ist, der einen Durchgang 33 (Figur 4) verschliesst. Dieser Durchgang 33 verbindet gemäss Figur 4 Durchgänge 10 des Einsatzes 32 mit dem Strömungskanal 13.In the guide member 18, an insert 32 is inserted, in which a further closure body 11 is mounted, which closes a passage 33 (Figure 4). According to FIG. 4, this passage 33 connects passages 10 of the insert 32 to the flow channel 13.

Das Druckreduzierventil 27 weist zudem eine Druckfeder 16 auf, die als Spiralfeder ausgebildet ist und die an einem Ende an einem Einstellmittel 17 und am anderen Ende am Führungsteil 18 des Kolbens 9 abgestützt ist. Das Einstellmittel 17 ist wie ersichtlich ringförmig ausgebildet und bildet für die Druckfeder 16 ein Gegenlager. Wie ersichtlich, umgibt das Einstellmittel den Düsenkörper 21 und ist an einer zylindrischen Innenfläche 34 des Gehäuses 6 verschiebbar geführt.The pressure reducing valve 27 also has a compression spring 16, which is designed as a spiral spring and which is supported at one end to an adjusting means 17 and at the other end on the guide part 18 of the piston 9. The adjusting means 17 is annular as shown and forms an abutment for the compression spring 16. As can be seen, the adjustment means surrounds the nozzle body 21 and is slidably guided on a cylindrical inner surface 34 of the housing 6.

Durch Verschieben bzw. Verstellen des Einstellmittels 17 kann die Vorspannung der Druckfeder 16 eingestellt werden. Hierzu besitzt das Einstellmittel 17 wenigstens einen Nocken 22, der gemäss Figur 5 durch ein Fenster 19 des Gehäuses 6 zugänglich ist. In diesem Fenster 19 sind gemäss den Figuren 5 bis 7 Ausnehmungen 20, 23 und 24 angeordnet, die jeweils einen Sitz für einen Nocken 22 bilden. Die Ausnehmungen20, 23 und 24 sind so ausgebildet, dass die entsprechenden Positionen des Nockens 22 stufenförmig in der Längsrichtung des Kanals 15 versetzt sind. Die in Figur 5 gezeigte Ausnehmung 20 bildet eine erste Position, bei welcher das Einstellmittel 17 am weitesten von der Mündung 14 entfernt ist. Die Vorspannung der Druckfeder 16 ist in dieser Position am geringsten. Die Ausnehmung 23 ergibt bei entsprechender Positionierung des Nockens 22 in dieser Ausnehmung 23 eine mittlere Vorspannung und die Ausnehmung 24 ergibt die grösste Vorspannung der Druckfeder 16. Die Einstellmittel 17 können zwischen diesen drei Positionen verstellt werden. Dies erfolgt, indem die Einstellmittel 17 an den beiden Nocken 22 gefasst, durch Drehen entriegelt, verschoben und durch nochmaliges Drehen wieder verriegelt werden. Grundsätzlich sind auch mehr oder weniger Stufen möglich. Zudem ist es denkbar, eine stufenlose Verstellung, beispielsweise mittels eines Gewindes zu ermöglichen. Die stufige Anordnung erleichtert jedoch die Einstellung.By moving or adjusting the adjusting means 17, the bias of the compression spring 16 can be adjusted. For this purpose, the adjusting means 17 has at least one cam 22, which is accessible according to Figure 5 through a window 19 of the housing 6. In this window 19 recesses 20, 23 and 24 are arranged according to the figures 5 to 7, each forming a seat for a cam 22. The recesses 20, 23 and 24 are formed so that the respective positions of the cam 22 are staggered in the longitudinal direction of the channel 15. The recess 20 shown in Figure 5 forms a first position in which the adjusting means 17 is furthest away from the mouth 14. The bias of the compression spring 16 is lowest in this position. The recess 23 results in a corresponding positioning of the cam 22 in this recess 23 has an average bias and the recess 24 gives the largest bias of the compression spring 16. The adjustment means 17 can be adjusted between these three positions. This is done by the adjusting means 17 taken on the two cams 22, unlocked by turning, moved and locked again by turning again. Basically, more or fewer levels are possible. In addition, it is conceivable to enable a stepless adjustment, for example by means of a thread. However, the step arrangement facilitates the adjustment.

Ist der Drucktank 2 mit Wasser gefüllt, so wirkt der Innendruck des Druckraumes 3 über die oben genannte Öffnung 8 auf die in Figur 4 mit B angedeutete Aussenfläche des Kolbens 9. In der Figur 3 ist mit dem Pfeil 26 die Richtung angedeutet, indem der Innendruck des Drucktanks 2 auf den Kolben 9 wirkt. Der Druck auf den Kolben 9 ist so gross, dass die Kraft der Druckfeder 12 überwunden wird und der Verschlusskörper 12 auf dem Ventilsitz 4 gehalten wird. In dieser Position ist die Mündung 4 des Kanals 15 verschlossen. Zudem liegt der Verschlusskörper 11 am Durchgang 33 an und verschliesst diesen.If the pressure tank 2 is filled with water, then the internal pressure of the pressure chamber 3 via the above-mentioned opening 8 acts on the indicated in Figure 4 with B outer surface of the piston 9. In the figure 3 is indicated by the arrow 26, the direction by the internal pressure of the pressure tank 2 acts on the piston 9. The pressure on the piston 9 is so great that the force of the compression spring 12 is overcome and the closure body 12 is held on the valve seat 4. In this position, the mouth 4 of the channel 15 locked. In addition, the closure body 11 abuts the passage 33 and closes it.

Wird eine Spülung ausgelöst, so entspannt sich die komprimierte Luft im Druckraum 3 und entsprechend nimmt der Druck auf die Fläche B des Kolbens 9 ab. Ist eine bestimmter Druck unterschritten, so verschiebt die Druckfeder 16 den Kolben 9 in Figur 3 nach links in die in Figur 4 gezeigte Position. Entsprechend wird der Verschlusskörper 12 nach links von der Mündung 14 weg und der Verschlusskörper 11 ebenfalls nach links vom Durchgang 33 wegverschoben. Durch den Kanal 15 kann nun Wasser in den Strömungskanal 13 strömen. Von diesem Strömungskanal 13 umströmt das Wasser den Verschlusskörper 12 und gelangt durch den Durchgang 33 und die seitlichen Durchgänge 10 zur Öffnung 8 und schliesslich durch das Rohr 30 in den Druckraum 3 des Drucktanks 2. Wird das hier nicht gezeigte Auslaufventil im Boden des Drucktanks 2 geschlossen, so füllt sich der Druckraum 3 mit Wasser und entsprechend wird die darin enthaltene Luft komprimiert. Ist der vorgesehene Druck von beispielsweise 1,5, 2, oder 2,5 bar im Druckraum 3 aufgebaut, so wirkt ein entsprechender Druck auf den Kolben 9. Da nun die Fläche 9 wesentlich grösser ist als eine Innenfläche A (Figur 4) des Kolbens 9, resultiert schliesslich eine Kraft, welche den Kolben 9 in Figur 4 nach rechts in die in Figur 3 gezeigte Position verschiebt. Diese Schliesskraft ist abhängig von der Vorspannung der Druckfeder 16 bzw. der eingestellten Position des Einstellmittels 17. Ist beispielsweise das Einstellmittel 17 in der Position gemäss Figur 5, so schliesst das Druckreduzierventil 27 bei beispielsweise 1,5 bar. Der mittlere Schliessdruck beträgt beispielsweise 2 bar und der höchste Schliessdruck 2,5 bar. Ist die Mündung 4 von dem Verschlusskörper 12 verschlossen, so verschiebt sich aufgrund des Drucks auch der Verschlusskörper 11 und verschliesst damit den Durchgang 33. Dieser maximale Druck wird aufrecht erhalten, bis wieder eine Spülung ausgelöst wird. Danach wiederholen sich die oben genannten Vorgänge, d.h. das Druckreduzierventil 27 wird wieder geöffnet, bis ein maximal vorgesehener Druck erreicht ist. Soll ein einmal eingestellter maximaler Druck verändert werden, so wird wie oben erwähnt das Einstellmittel 17 von Hand in eine andere Position gebracht. Da hier keine Teile ausgewechselt oder ersetzt werden müssen, ist eine solche Veränderung des maximalen Drucks ohne weiteres und in einfacher Weise möglich. Dies erleichtert einerseits insbesondere die Montage, aber auch die Lagerhaltung, da keine Austauschteile an Lager gehalten werden müssen.If a purge is triggered, the compressed air in the pressure chamber 3 relaxes and accordingly the pressure on the surface B of the piston 9 decreases. If a certain pressure falls below the pressure spring 16 moves the piston 9 in Figure 3 to the left in the position shown in Figure 4. Accordingly, the closure body 12 is moved away to the left of the mouth 14 and the closure body 11 also moved away to the left of the passage 33. Through the channel 15, water can now flow into the flow channel 13. From this flow channel 13, the water flows around the closure body 12 and passes through the passage 33 and the side passages 10 to the opening 8 and finally through the pipe 30 into the pressure chamber 3 of the pressure tank 2. The outlet valve, not shown here in the bottom of the pressure tank 2 is closed , so the pressure chamber 3 fills with water and accordingly the air contained therein is compressed. If the intended pressure of, for example, 1.5, 2, or 2.5 bar constructed in the pressure chamber 3, then a corresponding pressure on the piston 9 acts. Since now the surface 9 is substantially larger than an inner surface A (Figure 4) of the piston 9, finally results in a force which moves the piston 9 in Figure 4 to the right in the position shown in Figure 3. This closing force is dependent on the bias of the compression spring 16 and the adjusted position of the adjusting means 17. For example, if the adjusting means 17 in the position according to Figure 5, the pressure reducing valve 27 closes at, for example, 1.5 bar. The mean closing pressure is for example 2 bar and the highest closing pressure 2.5 bar. If the mouth 4 is closed by the closure body 12, the closure body 11 also shifts due to the pressure and thus closes off the passage 33. This maximum pressure is maintained until a purging is triggered again. Thereafter, the above operations are repeated, ie the pressure reducing valve 27 is opened again until a maximum intended pressure is reached. If a once set maximum pressure to be changed, as mentioned above, the adjusting means 17 is brought by hand in a different position. Since no parts have to be replaced or replaced here, such a change of the maximum pressure is easily and simply possible. This facilitates on the one hand in particular the assembly, but also the storage, since no replacement parts must be kept in stock.
