Abstract

The equipment has an operating device to start a full or partial flushing process from a toilet cistern, by lifting a valve member (7) from an outlet fitting (1). The member may be lifted along with a weight (13), which acts on the member against the buoyancy of a float (8), in order to close the valve early. A coupling device is arranged between the weight and the member, and has a switching element (20) mounted in the lower region of the weight. When the member is lifted by a pulling element (26), the switching element, which may be a pawl (19), automatically connects with the member.

Description

Die Erfindung betrifft eine Ablaufgarnitur sowie eine Spüleinrichtung in einem WC-Spülkasten gemäss Oberbegriff des Anspruchs 3. The invention relates to a drain set and a flushing device in a toilet cistern according to the preamble of the claim 3rd

Spüleinrichtungen und Ablaufgarnituren dieser Art sind bekannt und ermöglichen eine erhebliche Einsparung an Spülwasser. An einer weiten Verbreitung solcher Spüleinrichtungen und Ablaufgarnituren besteht deshalb ein starkes öffentliches Interesse. Die bisher bekannt gewordenen und in der Praxis eingesetzten Spüleinrichtungen sind in der Regel konstruktiv sehr aufwendig und bestehen aus vielen Einzelteilen. Die EP-A-0 715 033 bildet ein älteres Recht gemäss Artikel 54(3) EPÜ und offenbart eine Ablaufgarnitur in einer Spüleinrichtung für ein WC. Bei dieser Ablaufgarnitur wird im Fall einer Teilspülung der Gewichtskörper, der den Ventilkörper zum vorzeitigen Schliessen des Ventils belasten soll, mit einer Zugstange 3 angehoben, die über ein Kupplungsorgan 1 mit dem Gewichtskörper gekuppelt ist. Die Zugstange 3 und das Kupplungsorgan 1 sind nicht Teile des Gewichtskörpers. Die EP-A-0 448 092 zeigt eine Ablaufgarnitur und eine Spüleinrichtung, bei welcher der Ventilkörper in Ruhestellung mit einem Gewichtskörper verbunden ist. Im Fall einer Vollspülung wird der Gewichtskörper vom Ventilkörper getrennt. Im Fall einer Teilspülung wird hingegen der Gewichtskörper mit dem Ventilkörper angehoben.Flushing devices and drain fittings of this type are known and enable considerable savings in rinse water. At a widespread use of such flushing devices and drain sets there is therefore a strong public interest. The flushing devices that have become known and used in practice are usually very expensive and constructive consist of many individual parts. EP-A-0 715 033 constitutes a earlier right under Article 54 (3) EPC and discloses a drain set in a flushing device for a toilet. With this waste set in the case of partial rinsing, the weight body, which loads the valve body for premature closing of the valve is to be raised with a pull rod 3, which has a coupling member 1 is coupled to the weight body. The pull rod 3 and the coupling member 1 are not part of the weight body. EP-A-0 448 092 shows a drain set and a flushing device, in which the valve body with in the rest position a weight body is connected. In the case of a full flush the weight body is separated from the valve body. In the case of one Partial rinsing, however, becomes the weight body with the valve body raised.

Die deutsche Gebrauchsmusterschrift DE-U-92 15 972 zeigt eine Ablaufgarnitur, die ebenfalls eine Voll- oder Teilspülung ermöglicht. Diese arbeitet mit einem Hilfsventil und einem Zusatz-Hilfsventil sowie einer Entlastungskammer und ist ebenfalls sehr aufwendig ausgestaltet.The German utility model DE-U-92 15 972 shows one Drain fitting, which also enables full or partial flushing. This works with an auxiliary valve and an additional auxiliary valve as well as a relief chamber and is also very elaborately designed.

Schliesslich zeigt die DE-A-36 18 671 eine Spülvorrichtung in einem WC-Spülkasten, bei der zur Auslösung einer Teilspülung beim Anheben des Ventilkörpers mittels eines Steuerorgans ein am Schwimmergehäuse abgestütztes Gewicht mitgenommen wird.Finally, DE-A-36 18 671 shows a flushing device in a toilet cistern with which to trigger a partial flush when lifting the valve body by means of a control member carried a weight supported on the float housing becomes.

Der Erfindung liegt die Aufgabe zugrunde, eine Spüleinrichtung sowie eine Ablaufgarnitur zu schaffen, die einen einfacheren Aufbau und eine kostengünstigere Ausführung ermöglichen.The invention has for its object a flushing device as well as creating a pop-up waste that makes it easier Enable construction and a more cost-effective execution.

Die Aufgabe ist bei einer gattungsgemässen Ablaufgarnitur gemäss Anspruch 1 gelöst. Eine erfindungsgemässe Spüleinrichtung ergibt sich aus Anspruch 3.The task is with a generic waste set solved according to claim 1. A flushing device according to the invention results from claim 3.

Bei der erfindungsgemässen Ablaufgarnitur wird somit dessen Gehäuse zur Steuerung des Schaltorgans eingesetzt. Das Armaturengehäuse übernimmt damit eine zusätzliche Aufgabe. Das Schaltorgan kann damit in einem Spülkasten so tief angeordnet werden, dass es sich bei gefülltem Spülkasten im Spülwasser befindet und dadurch gegen Kalkablagerungen weniger anfällig ist. Damit kann die Betriebssicherheit wesentlich verbessert werden. Das Schaltorgan lässt sich weitgehend im Gehäuse der Ablaufgarnitur integrieren, so dass ein sehr kompakter Aufbau realisierbar ist. Dies ist insbesondere bei einem sogenannten Unterputz-Spülkasten äusserst vorteilhaft, da in einem solchen vor allem im oberen Bereich sehr wenig Raum zur Verfügung steht.With the drain fitting according to the invention, its Housing used to control the switching element. The valve body takes on an additional task. The switching element can thus be arranged so deep in a cistern be that when the cistern is full in the Rinse water is located and therefore less against limescale is vulnerable. This can make operational safety essential be improved. The switching element can be largely integrate in the housing of the waste set, so that a very compact structure can be realized. This is especially with a so-called concealed cistern Extremely advantageous, as in such an area above all Area very little space is available.

Ein konstruktiv besonders einfacher und betriebssicherer Aufbau wird dann erreicht, wenn bei der erfindungsgemässen Spüleinrichtung das Schaltorgan bzw. das Verbindungsorgan dass ein sehr kompakter Aufbau realisierbar ist. Dies ist insbesondere bei einem sogenannten Unterputz-Spülkasten äusserst vorteilhaft, da in einem solchen vor allem im oberen Bereich sehr wenig Raum zur Verfügung steht.A structurally particularly simple and reliable Structure is achieved when in the inventive Flushing device, the switching element or the connecting element that a very compact structure can be realized. This is especially with a so-called concealed cistern Extremely advantageous, as in such an area above all Area very little space is available.

Ein konstruktiv besonders einfacher und betriebssicherer Aufbau wird dann erreicht, wenn bei der erfindungsgemässen Spüleinrichtung das Schaltorgan bzw. das Verbindungsorgan eine Klinke aufweist. Diese kann dann insbesondere vom Gehäuse der Ablaufgarnitur angesteuert werden, um beim Anheben des Gewichtskörpers diesen am Ventilkörper einzuklinken. Zum Auslösen einer Teilspülung kann dann der Ventilkörper direkt am Gewichtskörper angehoben werden. Der Gewichtskörper ist dazu nach einer Weiterbildung der Erfindung mit einem nach oben ragenden Arm versehen, in den ein Zugelement eingreift. Dieses Zugelement kann ein Schwenkhebel sein, der eine von aussen bedienbare Taste besitzt. Beim Drücken der Taste greift dann das Zugelement direkt am Gewichtskörper an um diesen anzuheben. Das Ventilrohr wird mit dem Gewichtskörper mitgenommen. Beim Loslassen der Taste lastet der Gewichtskörper am Ventilkörper und zwingt diesen vor der vollständigen Entleerung des Spülkastens vorzeitig auf den Sitz des Ablaufventils.A structurally particularly simple and reliable Structure is achieved when in the inventive Flushing device, the switching element or the connecting element has a jack. This can then in particular from the housing the waste set to be controlled when lifting of the weight body to latch it onto the valve body. The valve body can then be used to trigger a partial flush be lifted directly on the weight body. The weight body is according to a development of the invention with an arm protruding upwards, into the one Pull element engages. This tension element can be a swivel lever be who has a button that can be operated from the outside. When the button is pressed, the pull element then engages directly on Weight body to lift it. The valve pipe will taken with the weight body. When you release the button the weight body rests on the valve body and forces this before the cistern is completely emptied early on the seat of the drain valve.

Zum Anheben des Ventilkörpers ist nach einer Weiterbildung der Erfindung am Gewichtskörper ein Anschlag angeordnet, der mit dem Ventilkörper in Wirkverbindung ist um diesen anzuheben. To lift the valve body is according to a training the invention arranged a stop on the weight body, that is operatively connected to the valve body around it to raise.

Nach einer Weiterbildung der Erfindung ist der Deckel der Ablaufgarnitur drehbar am Gehäuse der Ablaufgarnitur gelagert.Dies hat den Vorteil, dass die Ablaufgarnitur in jeder Drehstellung montiert werden kann. Dadurch wird eine automatische Montage der Spüleinrichtung bzw. der Ablaufgarnitur wesentlich vereinfacht.According to a development of the invention, the lid is the Drain fitting rotatably mounted on the housing of the drain fitting has the advantage that the waste set in each Rotary position can be mounted. This will make an automatic Installation of the flushing device or the waste set much simplified.

Wie die Figur 1 zeigt, ist ein Schwimmergehäuse 4 einer Ablaufgarnitur 1 an einem Ablaufstutzen 5 in einer Oeffnung 3 eines Spülkastens 2 befestigt. Zur Betätigung der Ablaufgarnitur 1 ist in einem hier nicht gezeigten oberen Bereich des Spülkastens 2 eine in Figur 3 schematisch gezeigte Betätigungsvorrichtung 33 angeordnet. Diese weist zwei Zugelemente 26 und 27 auf, die vorzugsweise unabhängig voneinander schwenkbar an einem Steg 28 des Spülkastens oder des Spülkastendeckels gelagert sind. Diese Elemente 26 und 27 weisen am einen Ende jeweils eine Taste 29 bzw. 30 auf, die von aussen zugänglich sind und zur Auslösung einer Spülung in der Regel von Hand zu betätigen sind. Das Zugelement 26 ist an dem der Taste 29 gegenüberliegenden Ende in eine Öse 14 eines Gewichtskörpers 13 eingesetzt. Beim Drücken der Taste 29 wird der Gewichtskörper 13 angehoben. Das andere Zugelement 27 greift mit dem der Taste 30 gegenüberliegenden Ende in eine Öse 24 eines Ventilkörpers 7 ein, der hier als Überlaufrohr ausgebildet ist. Beim Drücken der Taste 30 wird der Ventilkörper 7 angehoben. Zum Anheben des Gewichtskörpers 13 und des Ventilkörpers 7 können die Zugelemente 26 und 27 auch beispielsweise mittels eines Druckknopfes, wie er bei Keramikspülkästen üblich ist, betätigt werden. Denkbar sind auch andere Betätigungsvorrichtungen, mit denen wahlweise der Gewichtskörper 13 oder der Ventilkörper 7 angehoben werden können.As FIG. 1 shows, a float housing 4 is a waste set 1 on an outlet connection 5 in an opening 3 a cistern 2 attached. To operate the pop-up waste 1 is in an upper region, not shown here of the cistern 2 an actuating device shown schematically in Figure 3 33 arranged. This has two tension elements 26 and 27, which are preferably independent of one another pivotable on a web 28 of the cistern or the Cistern lid are stored. These elements 26 and 27 have at one end a button 29 and 30, respectively are accessible from the outside and to trigger a flush are usually operated by hand. The tension element 26 is in an eyelet at the end opposite the button 29 14 of a weight body 13 used. When pressing the Key 29, the weight body 13 is raised. The other Traction element 27 engages with the button 30 opposite End in an eyelet 24 of a valve body 7, which here is designed as an overflow pipe. When pressing button 30 the valve body 7 is raised. For lifting the weight body 13 and the valve body 7 can the tension elements 26 and 27 also, for example, by means of a push button, as is usual with ceramic cisterns become. Other actuating devices are also conceivable, with which either the weight body 13 or the valve body 7 can be raised.

Beim Anheben des Ventilkörpers 7 mit dem Zugelement 27 wird ein am unteren Körper des Ventilkörpers 7 angeordneter Teller 9 von einem Ventilsitz 10 der Ablaufgarnitur 1 angehoben. Im Spülkasten 2 vorhandenes Wasser kann dann durch Fenster 6 des Gehäuses 4 durch den Stutzen 5 in eine hier nicht gezeigte WC-Schüssel fliessen. Der angehobene Ventilkörper 7 wird durch den Schwimmer 8 in an sich bekannter Weise schwimmend gehalten, bis der Spülkasten im wesentlichen vollständig entleert ist. Durch Drücken der Taste 30 wird somit eine sogenannte Vollspülung ausgelöst. Der Gewichtskörper 13 ist hierbei unbeteiligt. Der Ventilkörper 7 ist zusammengesetzt aus einem unteren Teil 38 und einem auf diesen aufgerasteten oberen, rohrförmigen Teil 25. Der Teil 25 bildet eine Verlängerung des Ventilkörpers 7 und kann zur Anpassung an die Höhe des Spülkastens durch einen solchen mit einer anderen Länge ersetzt werden. Der Teil 25 ist mit zwei angeformten Rastzungen 25a am unteren Teil 38 lösbar aufgerastet.When lifting the valve body 7 with the tension element 27 a plate arranged on the lower body of the valve body 7 9 raised from a valve seat 10 of the drain fitting 1. Water present in the cistern 2 can then pass through Window 6 of the housing 4 through the nozzle 5 in one here Flow toilet bowl, not shown. The raised valve body 7 is known per se by the float 8 Way kept floating until the cistern essentially is completely empty. By pressing button 30 a so-called full flush is triggered. The weight body 13 is not involved in this. The valve body 7 is composed of a lower part 38 and one this snapped upper tubular part 25. The part 25 forms an extension of the valve body 7 and can to adapt to the height of the cistern by such be replaced with a different length. Part 25 is with two molded locking tongues 25a on the lower part 38 releasably snapped on.

Zur Auslösung einer Teilspülung wird die Taste 29 betätigt und damit der Gewichtskörper 13 angehoben. Dieser Körper 13 ist an seinem unteren Ende mit angeformten Stelzen 17 auf einem Deckel 12 des Gehäuses 4 abgestützt und am Ventilkörper 7 verschieblich geführt. Ein oben offener Behälter 16 ist mit Wasser 34 gefüllt, welches bei teilweise geleertem Spülkasten ein zusätzliches Gewicht bildet. Unterhalb des Behälters 16 sind die genannten Stelzen 17 angeformt, die im Abstand zueinander gegenüberliegen und nach unten ragen. Wie die Figuren 5 und 7 zeigen, ist an den Stelzen 17 jeweils eine querverlaufende Wandung 17a angeformt, welche die Stelzen 17 verstärken und den Gewichtskörper 13 am Ventilrohr 7 stabilisieren. Ein nach unten versetzter Deckel 12, der mit einer Rastverbindung 31 am Gehäuse 4 drehbar befestigt ist, trägt den Gewichtskörper 13, der auf einer Oberseite 12a dieses Teils 12 abgestellt ist.The key 29 is actuated to trigger a partial rinse and thus the weight body 13 is raised. This body 13 is on at its lower end with molded stilts 17 a cover 12 of the housing 4 is supported and on the valve body 7 slidably guided. A container 16 open at the top is filled with water 34, which is partially emptied Cistern forms an additional weight. Below the Container 16, the stilts 17 are formed, the at a distance from each other and protrude downwards. As FIGS. 5 and 7 show, there is 17 on each of the stilts a transverse wall 17a is formed, which reinforce the stilts 17 and the weight body 13 on the valve tube 7 stabilize. A lid set down 12, which can be rotated on the housing 4 with a latching connection 31 attached, carries the weight body 13, which on a Top 12a of this part 12 is turned off.

Der Deckel 12 ist mit einer Öffnung 12b versehen, in die ein Arm 21 einer Klinke 20 eingreift. Diese Klinke 20 ist an einem in Figur 8 gezeigten Lager 18 schwenkbar gelagert und bildet ein Verbindungs- oder Schaltorgan. Die Klinke 20 ist wie ersichtlich als einarmiger Hebel ausgebildet, der an seinem oberen Ende schwenkbar gelagert ist. Eine unterhalb der Schwenkachse S angeordnete, radial nach aussen gerichtete Nase 20a ist auf die Oberseite 12a aufgesetzt und hält den Arm 21 in der in Figur 1 gezeigten Stellung. Die Klinke 20 ist lösbar in eine Rastöffnung 18a (Figur 8) einer Stelze 17 eingerastet.The lid 12 is provided with an opening 12b into which an arm 21 of a pawl 20 engages. This jack is 20 is pivotally mounted on a bearing 18 shown in FIG and forms a connection or switching element. The jack 20 is designed as a one-armed lever, as can be seen is pivotally mounted at its upper end. One below the pivot axis S arranged radially outward Nose 20a is placed on top 12a and holds the arm 21 in the position shown in Figure 1. The Pawl 20 is detachable into a latching opening 18a (FIG. 8) Stilt 17 snapped into place.

Wird zur Auslösung einer Teilspülung der Gewichtskörper 13 angehoben, so wird gleichzeitig der Ventilkörper 7 durch die Anlage wenigstens eines am Ventilkörper 7 angeformten Steges 32 an der seitlich vorstehenden Unterseite 25b einer Rastzunge 25a gleichzeitig ebenfalls angehoben. Die etwa am unteren Ende des Gewichtskörpers 13 angebrachte Klinke 20 wird gleichzeitig vom Deckel 12 abgehoben, wobei ein Rand 12c mit dem Arm 21 in Eingriff kommt und dieser den Arm 21 in Richtung des Pfeils 36 nach innen zum Ventilkörper 7 hin verschwenkt. Ein Absatz 22 des Arms 21 wird dadurch radial nach innen in eine Position bewegt, in welcher dieser über einer nach aussen ragenden Schulter 23 liegt. Dies ist die stabile Lage der Klinke 20, die bei angehobenem Gewichtskörper 13 beibehalten wird. Wie bei einer Vollspülung wird der Ventilteller 9 vom Ventilsitz 10 abgehoben und damit die Spülung ausgelöst. Durch den Schwimmer 8 wird wiederum am Ventilkörper 7 eine Auftriebskraft ausgeübt. Der Gewichtskörper 13 wird bei sinkendem Spülwasserniveau 37 zunehmend schwerer. Durch die an der Schulter 23 aufliegende Klinke 20 lastet das zunehmend grösser werdende Gewicht des Gewichtskörpers 13 auf dem Ventilkörper 7. Der Gewichtskörper 13 ist so ausgebildet, dass er nach einer vergleichsweise kurzen Zeit nach Auslösung der Spülung die Auftriebskraft des Schwimmers 8 überwindet und den Ventilkörper 7 vor der vollständigen Entleerung des Spülkastens 2 auf den Ventilsitz 10 zwingt und damit die Spülung unterbricht. Bei dieser Schliessbewegung trifft die Nase 20a der Klinke 20 auf die Fläche 12a auf und verschwenkt den Arm 21 wieder in die in Figur 1 gezeigte Position, in welcher der Absatz 22 sich radial neben der Schulter 23 befindet und somit der Ventilkörper 7 zur Auslösung einer Vollspülung ohne Gewichtskörper 13 angehoben werden kann. Nach Beendigung der Spülung wird der Spülkasten in bekannter Weise durch ein hier nicht gezeigtes Einlaufventil wieder auf das in Figur 1 angedeutete Niveau 37 aufgefüllt. Die Spüleinrichtung ist damit für eine wahlweise Teil- oder Vollspülung wieder bereit.Is the weight body 13 to trigger a partial rinse raised, the valve body 7 is simultaneously through the system of at least one molded on the valve body 7 Web 32 on the laterally projecting bottom 25b one Locking tongue 25a also raised at the same time. The about on pawl 20 attached to the lower end of the weight body 13 is lifted off the lid 12 at the same time, with an edge 12c engages with the arm 21 and this arm 21 in the direction of arrow 36 towards the valve body 7 panned. A shoulder 22 of the arm 21 thereby becomes radial moved inwards into a position in which this over an outwardly projecting shoulder 23 lies. this is the stable position of the pawl 20, the weight body raised 13 is maintained. As with a full flush the valve disk 9 is lifted off the valve seat 10 and thus the flush is triggered. By the float 8 in turn exerted a buoyancy force on the valve body 7. The weight body 13 is increasing with sinking rinse water level 37 heavier. By lying on the shoulder 23 Jack 20 weighs the increasingly larger weight of the Weight body 13 on the valve body 7. The weight body 13 is designed so that it is comparatively shortly after the flush is triggered, the buoyancy of the float 8 overcomes and the valve body 7 before completely flushing the cistern 2 to the Valve seat 10 forces and thus interrupts the flushing. At this closing movement hits the nose 20a of the pawl 20 onto the surface 12a and swings the arm 21 back in the position shown in Figure 1, in which the paragraph 22nd is located radially next to the shoulder 23 and thus the Valve body 7 for triggering a full flush without a weight body 13 can be raised. After completing the Flushing the cistern in a known manner by Inlet valve, not shown here, back to the one in FIG 1 indicated level 37 filled. The rinsing device is ready for an optional partial or full flush.

Die Ausführung nach Figur 2 ist ähnlich wie diejenige gemäss Figur 1 aufgebaut und funktioniert auch ähnlich. Sie ist jedoch weniger hoch und für einen Aufputz-Spülkasten vorgesehen. Die Betätigungsvorrichtung kann gleich wie die in Figur 3 gezeigte Vorrichtung 33 ausgebildet sein. Das Zugelement 26 ist dann mit einem Gewichtskörper 113 verbunden, an dem ein nach oben ragender Arm 115 angeformt ist. Über einem Behälter 116, der sich bei gefülltem Spülkasten 102 unterhalb des Spülwasserniveaus 37 befindet, ist ein Steg 141 angeformt, der an einem vorstehenden Ansatz 140 eines Ventilkörpers 107 einen Anschlag bildet. Beim Anheben des Gewichtskörpers 113 mit dem Zugelement 26 wird damit gleichzeitig der Ventilkörper 107 angehoben. Die an einer Oberseite 111a eines Deckels 111 aufliegende Nase 120a einer Klinke 120 wird vom Deckel 111 abgehoben, wonach der Arm 121 in Richtung des Pfeiles 136 verschwenkt wird und dieser den Gewichtskörper 113 bei angehobenem Ventilkörper 107 an einer Schulter 123 abstützt. Die Schulter 123 ist wie bei der Ausführung gemäss Figur 1 innerhalb des Gehäuses 104 angeordnet. Der Deckel 111 ist wie der Deckel 12 mit einer Rastvorrichtung 131 am Gehäuse 104 drehbar befestigt. Die Rastvorrichtung 131 ist so ausgebildet, dass der Deckel 111 auf dem Gehäuse 104 frei drehbar ist. Dies gilt auch für den Deckel 12. Der Gewichtskörper 113 ist somit in jeder Position um die Achse A des Ventilkörpers 107 drehbar und kann dadurch genau auf das Zugelement 26 ausgerichtet werden. Denkbar ist auch eine Ausführung, bei welcher die Funktion des Steges 141 durch die Klinke 120 übernommen wird. Ebenfalls denkbar ist eine Ausführung, bei der ein weiteres Schaltelement vorgesehen ist, welches die Funktion des Steges 141 übernimmt. Wie ersichtlich ist der Ventilkörper 107 weitgehend wie üblich ausgebildet und nicht durch irgendwelche Schaltelemente oder sonstige Teile, welche sein Gewicht erhöhen würden belastet. Der Auftrieb des Schwimmers 108 kann damit minimal und das Schwimmergehäuse 104 entsprechend schlank ausgebildet sein. Dies ist insbesondere für eng gebaute Unterputz-Spülkästen wesentlich.The embodiment according to FIG. 2 is similar to that according to FIG Figure 1 constructed and works similarly. she is however less high and for a surface-mounted cistern intended. The actuator can be the same as that Device 33 shown in Figure 3 may be formed. The Pulling element 26 is then connected to a weight body 113, on which an upwardly projecting arm 115 is formed. Above a container 116, which is when the cistern is full 102 is located below the rinse water level 37 is a Web 141 integrally formed on a projection 140 of a valve body 107 forms a stop. When lifting of the weight body 113 with the tension element 26 at the same time the valve body 107 is raised. The one Top 111a of a lid 111 resting nose 120a one Pawl 120 is lifted off the cover 111, after which the Arm 121 is pivoted in the direction of arrow 136 and this the weight body 113 with the valve body raised 107 is supported on a shoulder 123. The shoulder is 123 as in the embodiment according to FIG. 1 inside the housing 104 arranged. The lid 111 is like the lid 12 with a locking device 131 rotatably attached to the housing 104. The locking device 131 is designed so that the Cover 111 is freely rotatable on the housing 104. this applies also for the cover 12. The weight body 113 is thus in any position rotatable about the axis A of the valve body 107 and can thereby be aligned precisely with the tension element 26 become. An embodiment is also conceivable in which the Function of the web 141 taken over by the pawl 120 becomes. An embodiment in which a Another switching element is provided, which has the function of web 141 takes over. As can be seen, the valve body 107 largely trained as usual and not by any switching elements or other parts which his weight would increase. The buoyancy of the Float 108 can be minimal and the float housing 104 be designed to be correspondingly slim. This is particularly so essential for narrow concealed cisterns.
