Description

Die Erfindung betrifft ein Ablaufventil fur einen Spülkasten nach dem Oberbegriff des Anspruchs 1.The invention relates to a drain valve for a cistern according to the preamble of claim 1.

Ablaufventile für Spülkästen sind seit langem bekannt. Bewährt haben sich insbesondere Ablaufventile, welche eine Teilspülung mit beispielsweise drei Litern Spülwasser ermöglichen. Bei einem solchen Spülkasten kann wahlweise eine Vollspülung oder eine Teilspülung gewählt werden. In der Regel sind hierzu zwei Tasten für die Spülauslösung vorgesehen. Beim Drücken der einen Taste wird eine Teilspülung und beim Drücken der anderen Taste eine Vollspülung ausgelöst.Drain valves for cisterns have long been known. In particular, drainage valves which enable partial flushing with, for example, three liters of rinsing water have proved to be useful. In such a cistern, either a full flush or a partial flush can be selected. As a rule, two buttons are provided for flushing. Pressing one key causes a partial flush and a full flush when the other key is pressed.

Ein Ablaufventil, das eine solche Zweistufen-Spülung ermöglicht, ist aus der EP 0 722 020 B bekannt geworden. Bei diesem Ablaufventil wird zur Spülauslösung der Ventilkörper angehoben. Bei einer Teilspülung steuert ein Schwimmer einen Hebel, welcher den Ventilkörper vorzeitig freigibt, so dass dieser vor der Entleerung des Spülkastens auf den Ventilsitz fällt. In der Praxis hat sich dieses Ablaufventil vielfach bewährt. Das Ablaufventil hat den Vorteil, dass es sehr kompakt gebaut werden kann. Die Betätigungskraft als auch der Betätigungsweg beim Öffnen und Schliessen des Ventils sind aber vergleichsweise gross.A drain valve that allows such a two-stage flush is out of the EP 0 722 020 B became known. With this drain valve, the valve body is raised to initiate the flushing process. In a partial flush a float controls a lever which prematurely releases the valve body so that it falls onto the valve seat prior to emptying the flushing cistern. In practice, this drain valve has proven itself many times. The drain valve has the advantage that it can be built very compact. The actuating force as well as the actuating travel when opening and closing the valve but are relatively large.

Durch die DE 92 15 972 U ist ein gattungsgemässes Ablaufventil bekannt geworden, bei dem die Spülauslösung mit einer kleineren Betätigungskraft möglich sein soll. Das Ablaufventil weist einen Hauptventilkörper auf, der durch Betätigen eines Hilfsventils mittels einer Betätigungseinrichtung aufgrund einer sich in einer Entlastungskammer einstellenden negativen Wasserbilanz von seinem Sitz abhebbar ist. Beim Entleeren der Entlastungskammer bildet sich in dieser ein Unterdruck, welcher den Hauptventilkörper in der Art eines Kolbens anhebt. Zur wahlweisen Teilentleerung ist ein Zusatz-Hilfsventil vorgesehen, das zum Fluten der Entlastungskammer zumindest kurzzeitig zu öffnen ist. Beim Fluten der Entlastungskammer bildet sich eine positive Wasserbilanz, wodurch der Hauptventilkörper vorzeitig schliesst. Dem Zusatz-Hilfsventil ist zur Teilentleerung ein Schwimmkörper zugeordnet. Das Hilfsventil besitzt einen Hilfsventilkörper, der zur Auslösung der Spülung nach unten zu bewegen ist. Hierbei wird eine Feder gespannt. Dieses Ablaufventil besteht aus vergleichsweise vielen Einzelteilen und erfordert ein vergleichsweise grosses Bauvolumen, was insbesondere bei Unterputzspülkästen nachteilig ist.By the DE 92 15 972 U is a generic drain valve has become known in which the Spülauslösung should be possible with a smaller actuation force. The drain valve has a main valve body, which can be lifted from its seat by actuating an auxiliary valve by means of an actuating device due to a negative water balance occurring in a relief chamber. When emptying the discharge chamber forms in this a negative pressure, which raises the main valve body in the manner of a piston. For optional partial emptying an auxiliary auxiliary valve is provided, which is at least to open briefly to flood the discharge chamber. When the discharge chamber floods, a positive water balance is formed, causing the main valve body to prematurely close. The auxiliary auxiliary valve is assigned to a partial emptying a floating body. The auxiliary valve has an auxiliary valve body, which is to move down to trigger the flushing. This is a spring tensioned. This drain valve consists of comparatively many individual parts and requires a comparatively large volume of construction, which is particularly disadvantageous in concealed cisterns.

Durch die EP 1 270 831 ist ein Ablaufventil bekannt geworden, das ebenfalls ein Hilfsventil aufweist und eine Auslösung mit einer vergleichsweise kleinen Betätigungskraft ermöglicht. Sowohl das Öffnen als auch das Schliessen des Hilfsventils ist schwimmergesteuert. Das Schliessen des Ventils erfolgt verzögert, was nachteilig ist.By the EP 1 270 831 is a drain valve has become known, which also has an auxiliary valve and allows a release with a comparatively small actuation force. Both the opening and closing of the auxiliary valve is float controlled. The closing of the valve is delayed, which is disadvantageous.

Der Erfindung liegt die Aufgabe zugrunde, ein Ablaufventil der genannten Art zu schaffen, das eine Teilspülung ermöglicht und mit möglichst kleiner Betätigungskraft und kleinem Betätigungsweg geöffnet und geschlossen werden kann und das dennoch kompakt und mit vergleichsweise kleinem Volumen gebaut werden kann. Das Ablaufventil soll zudem funktionssicher sein.The invention has for its object to provide a drain valve of the type mentioned, which allows partial flushing and can be opened and closed with the smallest possible operating force and small actuation travel and can still be built compact and with relatively small volume. The drain valve should also be reliable.

Die Aufgabe ist bei einem gattungsgemässen Ablaufventil gemäss Anspruch 1 gelöst.The object is achieved in a generic drain valve according to claim 1.

Beim erfindungsgemässen Ablaufventil ist ein separates Zusatz-Hilfsventil mit einem entsprechenden zweiten Hilfsventilkörper nicht erforderlich. Das Hilfsventil, mit dem die Entlastungskammer wenigstens teilweise entleert wird und das zweite Hilfsventil, mit dem die Entlastungskammer geflutet wird, werden mit demselben Hilfsventilkörper bedient. Mit der gleichen Belegung des Hilfsventilkörpers, mit dem die Ventilöffnung des ersten Hilfsventils freigegeben wird, wird auch die Ventilöffnung des zweiten Hilfsventils geschlossen. Das Öffnen der Ventilöffnung des ersten Hilfsventils und das Schliessen der Ventilöffnung des zweiten Hilfsventils kann mit einer vergleichsweise kurzen Hubbewegung des Hilfsventilkörpers und damit mit einem entsprechend kurzen Betätigungsweg erfolgen. Dies ermöglicht einen wesentlich einfacheren und kompakteren Aufbau des Ablaufventils. Aufgrund der kleinen Betätigungskraft und des kleinen Betätigungsweges eignet sich das Ablaufventil besonders für eine motorische Betätigung.When the drain valve according to the invention, a separate auxiliary auxiliary valve with a corresponding second auxiliary valve body is not required. The auxiliary valve with which the discharge chamber is at least partially emptied and the second auxiliary valve, with which the discharge chamber is flooded, are operated with the same auxiliary valve body. With the same occupancy of the auxiliary valve body with which the valve opening of the first auxiliary valve is released, and the valve opening of the second auxiliary valve is closed. The opening of the valve opening of the first auxiliary valve and the closing of the valve opening of the second auxiliary valve can be carried out with a comparatively short stroke movement of the auxiliary valve body and thus with a correspondingly short actuating travel. This allows a much simpler and more compact construction of the drain valve. Due to the small actuating force and the small actuating travel, the drain valve is particularly suitable for a motorized operation.

Ein besonders kompakter Aufbau ergibt sich dann, wenn gemäss einer Weiterbildung der Erfindung die Ventilöfnung des ersten Hilfsventils und die Ventilöffnung des zweiten Hilfsventils am Hauptventilkörper angeordnet sind. Damit kann zudem die Anzahl der Einzelteile wesentlich verkleinert werden.A particularly compact design results when, according to a development of the invention, the valve opening of the first auxiliary valve and the valve opening of the second auxiliary valve are arranged on the main valve body. This also allows the number of items to be significantly reduced.

Ein noch einfacherer Aufbau ergibt sich dann, wenn gemäss der Erfindung der Hilfsventilkörper zwischen der Ventilöffnung des ersten Hilfsventils und der Ventilöffnung des zweiten Hilfsventils vertikal bewegbar ist, wobei die beiden Hilfsventilöffnungen übereinander, vorzugsweise unmittelbar übereinander angeordnet sind. Durch eine vergleichsweise kleine vertikale Bewegung des Hauptventilkörpers kann das erste Hilfsventil geöffnet und das zweite Hilfsventil geschlossen werden. Dadurch ist ein besonders kurzer Betätigungsweg möglich.An even simpler structure results when, according to the invention, the auxiliary valve body is vertically movable between the valve opening of the first auxiliary valve and the valve opening of the second auxiliary valve, wherein the two auxiliary valve openings are arranged one above the other, preferably directly above one another. By a comparatively small vertical movement of the main valve body, the first auxiliary valve can be opened and the second auxiliary valve can be closed. As a result, a particularly short actuation path is possible.

Vorzugsweise wird das erste Hilfsventil durch Anheben des Hauptventilkörpers geöffnet und mit dem gleichen Hub die Ventilöffnung des zweiten Hauptventilkörpers geschlossen.Preferably, the first auxiliary valve is opened by lifting the main valve body and closed with the same stroke, the valve opening of the second main valve body.

Nach einer Weiterbildung der Erfindung ist vorgesehen, dass der Hauptventilkörper in seiner Grundstellung von einer ersten Klinke nach unten gehalten ist und dass diese Klinke bei einer Spülauslösung so verschwenkt wird, dass sie den Hauptventilkörper freigibt.According to a development of the invention, it is provided that the main valve body is held in its basic position by a first pawl down and that this pawl is pivoted at a Spülauslösung so that it releases the main valve body.

Nach einer Weiterbildung der Erfindung ist vorgesehen, dass am Hilfsventilkörper eine zweite Klinke angeordnet ist, mit welcher der Hilfsventilkörper mit dem Hauptventilkörper verbunden wird. Dies ermöglicht ein besonders funktionssicheres Öffnen der Ventilöffnung des ersten Hilfsventils.According to a development of the invention it is provided that a second pawl is arranged on the auxiliary valve body, with which the auxiliary valve body is connected to the main valve body. This allows a particularly reliable opening of the valve opening of the first auxiliary valve.

Nach einer Weiterbildung der Erfindung ist zur Auslösung der Teilspülung vorgesehen, dass die zweite Klinke mit einem Schwimmer zusammenarbeitet, welcher den Hilfsventilkörper beim Erreichen eines vorbestimmten Spülwasserniveaus freigibt.According to a development of the invention, it is provided for triggering the partial flush that the second latch cooperates with a float, which releases the auxiliary valve body upon reaching a predetermined Spülwasserniveaus.

Eine besonders kostengünstige Herstellung und ein kompakter Aufbau ergibt sich dann, wenn gemäss einer Weiterbildung der Erfindung die Ventilöffnung des ersten Hilfsventils und die Ventilöffnung des zweiten Hilfsventils am Hauptventilkörper angeordnet sind.A particularly cost-effective production and a compact construction results when, according to a development of the invention, the valve opening of the first auxiliary valve and the valve opening of the second auxiliary valve are arranged on the main valve body.

Die Figur 1 zeigt abschnittsweise einen Spülkasten 1, der wie üblich ausgebildet sein kann und eine hier nicht gezeigte Betätigungsvorrichtung aufweist. Der Spülkasten 1 weist an einem Boden 11 einen üblichen Ablaufstutzen 12 auf, in den ein Ablaufventil 10 eingesetzt ist. Im Spülkasten 1 ist gemäss Figur 2 Spülwasser 66 gelagert. Das Volumen des Spülwassers 66 beträgt beispielsweise bei gefülltem Spülkasten 1, sechs oder neun Liter. In Figur2 ist die Wasseroberfläche 46 bei gefüllten Spülkasten 1 gezeigt. Das Ablaufventil 10 dient zum Entleeren des Spülkastens 1, wobei es beispielsweise zur Betätigung einer hier nicht gezeigten Taste geöffnet wird und Spülwasser durch den Auslaufstutzen 12 in eine hier nicht gezeigte WC-Schüssel strömt. Die Spülauslösung erfolgt wie erwähnt beispielsweise durch Betätigen einer Taste. Grundsätzlich ist aber auch eine berührungslose motorische Betätigung denkbar.The FIG. 1 shows in sections a cistern 1, which may be formed as usual and has an actuating device, not shown here. The cistern 1 has at a bottom 11 a conventional outlet nozzle 12, in which a drain valve 10 is inserted. In the cistern 1 is according FIG. 2 Rinse water 66 stored. The volume of the rinse water 66 is, for example, with a full cistern 1, six or nine liters. In Figur2 the water surface 46 is shown with the cistern 1 filled. The drain valve 10 is used to empty the cistern 1, where it is opened, for example, to actuate a button, not shown here and rinse water flows through the outlet nozzle 12 in a toilet bowl, not shown here. The flushing takes place as mentioned, for example by pressing a button. Basically, however, a non-contact motor control is conceivable.

Das Ablaufventil 10 besitzt ein Ventilgehäuse 2, das eine Ventilöffnung 5 besitzt. Über dieser Ventilöffnung 5 sind im Ventilgehäuse 2 mehrere seitliche Öffnungen 15 angeordnet, durch welche Spülwasser 66 bei geöffneter Ventilöffnung 5 in den Auslaufstutzen 12 und damit in die WC-Schüssel strömen kann.The drain valve 10 has a valve housing 2, which has a valve opening 5. Over this valve opening 5 a plurality of side openings 15 are arranged in the valve housing 2, through which rinse water 66 can flow with open valve opening 5 in the outlet pipe 12 and thus in the toilet bowl.

Die Ventilöffnung 5 bildet mit einem Hauptventilkörper 3 ein Hauptventil V. Der Hauptventilkörper 3 besitzt einen Ventilteller 14, der in Figur 1 auf einem Ventilsitz 13 aufliegt. Das Hauptventil V ist in den Figuren 1 bis 3 geschlossen.The valve opening 5 forms a main valve body 3 with a main valve V. The main valve body 3 has a valve plate 14 which in FIG. 1 rests on a valve seat 13. The main valve V is in the FIGS. 1 to 3 closed.

Der Ventilkörper 3 besitzt an seinem Umfang einen Kolbenring 16, der an einer Innenseite 17 einer Entlastungskammer 4 vertikal verschiebbar dichtend anliegt. Der Hauptventilkörper 3 dichtet mit dem Dichtungsring 16 die Entlastungskammer 4 nach unten ab. Er bildet einen Kolben, der zwischen der in Figur 1 gezeigten unteren Stellung und einer in Figur 4 gezeigten oberen Stellung mit dem in Figur 6 gezeigten Hub H3 begrenzt vertikal bewegbar ist.The valve body 3 has at its periphery a piston ring 16 which bears against an inner side 17 of a discharge chamber 4 in a vertically displaceable sealing manner. The main valve body 3 seals with the sealing ring 16 the discharge chamber 4 down from. He forms a piston between the in FIG. 1 shown lower position and one in FIG. 4 shown upper position with the in FIG. 6 shown limited stroke H3 is vertically movable.

Am Hauptventilkörper 3 ist ein Hilfsventilkörper 7 gelagert, der in Figur 1 auf einem Ventilsitz 18 eines ersten Hilfsventils HV1 aufliegt. Über diesem Ventilsitz 18 ist ein zweiter Ventilsitz 21 eines zweiten Hilfsventils HV2 angeordnet. Dieser zweite Ventilsitz 21 wird durch ein Rohr 67 gebildet, welches am Hauptventilkörper 3 durch hier nicht gezeigte Stege angeformt ist und einen oberen Rand 34 aufweist. Das Rohr 67 ist an einer oberen Kante 34 offen und weist einen Kanal 6 auf, welcher an einem unteren Ende die Ventilöfnung des zweiten Hilfsventils HV2 bildet. Der Hilfsventilkörper 3 ist somit der gemeinsame Ventilkörper für das erste Hilfsventil HV1 und das zweite Hilfsventil HV2. Der Hilfsventilkörper 7 weist einen Ventilteller 19 auf, der bei geschlossenem Hilfsventil HV1 auf einem Ventilsitz 18 aufliegt. In der Figur 1 ist das erste Hilfsventil HV1 geschlossen und das zweite Hilfsventil HV2 geöffnet. Der Hilfsventilkörper 7 ist zwischen der in Figur 1 gezeigten unteren Stellung und der in Figur 3 gezeigten oberen Stellung mit einem vergleichsweisen kurzen Hub bewegbar. Dieser Hub ist wesentlich kürzer als der Hub H3 des Hauptventilkörpers 3. Zudem ist die zum Anheben des Hilfsventilkörpers 7 erförderliche Kraft vergleichsweise klein. Bei der in Figur 3 gezeigten Stellung ist das zweite Hilfsventil HV2 geschlossen, das erste Hilfsventil HV1 jedoch geöffnet.At the main valve body 3, an auxiliary valve body 7 is mounted, which in FIG. 1 rests on a valve seat 18 of a first auxiliary valve HV1. Above this valve seat 18, a second valve seat 21 of a second auxiliary valve HV2 is arranged. This second valve seat 21 is formed by a pipe 67, which is integrally formed on the main valve body 3 by webs not shown here and has an upper edge 34. The tube 67 is open at an upper edge 34 and has a channel 6, which forms the Ventilöfnung of the second auxiliary valve HV2 at a lower end. The auxiliary valve body 3 is thus the common valve body for the first auxiliary valve HV1 and the second auxiliary valve HV2. The auxiliary valve body 7 has a valve disk 19 which rests on a valve seat 18 when the auxiliary valve HV1 is closed. In the FIG. 1 the first auxiliary valve HV1 is closed and the second auxiliary valve HV2 is opened. The auxiliary valve body 7 is between the in FIG. 1 shown lower position and the in FIG. 3 shown upper position with a comparatively short stroke movable. This stroke is much shorter than the stroke H3 of the main valve body 3. In addition, the force required to lift the auxiliary valve body 7 is comparatively small. At the in FIG. 3 shown position, the second auxiliary valve HV2 is closed, the first auxiliary valve HV1, however, open.

Der Hauptventilkörper 3 besitzt an einer Oberseite 44 wenigstens eine Steueröffnung 20, welche zur Entlastungskammer 4 hin offen ist und welche bei geöffnetem ersten Hilfsventil HV1 die Entlastungskammer 4 mit einer Öffnung 68 des ersten Hilfsventil HV1 verbindet. Diese Öffnung 68 führt in die Hauptventilöffnung 5. Bei geöffnetem ersten Hilfsventil HV1 kann in der Entlastungskammer 4 vorhandenes Wasser durch die Steueröffnung 20 in die Öffnung 68 und damit in den Auslaufstutzen 12 abfliessen.The main valve body 3 has on an upper side 44 at least one control opening 20 which is open towards the relief chamber 4 and which connects the relief chamber 4 to an opening 68 of the first auxiliary valve HV1 when the first auxiliary valve HV1 is open. This opening 68 leads into the main valve opening 5. When the first auxiliary valve HV1 is opened, water present in the relief chamber 4 can flow out through the control opening 20 into the opening 68 and thus into the outlet connection 12.

Das Rohr 67 des Hauptventilkörpers 3 überragt bei geschlossenem Hauptventil V das Ventilgehäuse 2, wie die Figur 1 zeigt. In diesem Rohr 67 ist der Hilfsventilkörper 7 gelagert. Dieser Hilfsventilkörper 7 überragt mit einem oberen Ende ebenfalls das Ventilgehäuse 2 und besitzt einen Überlaufkanal 22. Der Hilfsventilkörper 7 bildet in diesem Fall ein Überlaufrohr, welches die maximale Füllung des Spülkastens 1 bestimmt. Der Überlaufkanal 22 kann aber in an sich bekannter Weise auch ausserhalb des Ablaufventils 10 angeordnet sein. Der Hilfsventilkörper 7 ist somit nicht zwingend ein Überlaufrohr.The pipe 67 of the main valve body 3 projects beyond the main valve V closed valve housing 2, as the FIG. 1 shows. In this tube 67 of the auxiliary valve body 7 is mounted. This auxiliary valve body 7 also projects beyond an upper end Valve housing 2 and has an overflow channel 22. The auxiliary valve body 7 forms in this case an overflow pipe, which determines the maximum filling of the cistern 1. However, the overflow channel 22 can also be arranged in a manner known per se outside the drainage valve 10. The auxiliary valve body 7 is thus not necessarily an overflow pipe.

Am Ventilgehäuse 2 ist ein Schwimmer 69 gelagert, der in einem Gehäuse 25 eine Luftkammer 26 sowie eine Wasserkammer 27 bildet. Diese beiden Kammern 26 und 27 sind durch eine Bodenwandung 32 voneinander getrennt. In der Luftkammer 26 befindet sich auch bei gefülltem Spülkasten immer Luft und in der Wasserkammer 27 immer Wasser. Die Luft in der Luftkammer 26 verursacht eine Auftriebskraft gemäss Pfeil 28 und das Wasser in der Wasserkammer 27 bei einer teilweisen Entleerung des Spülkastens (Fig. 5) ein Gewicht gemäss Pfeil 29. Am Schwimmer 69 ist ein Stab 23 befestigt, der nach unten in eine Kammer 70 des Ventilgehäuses 2 ragt. Am Stab 23 ist ein Anschlagnocken 24 angeformt, der einen maximalen Hub H1 ermöglicht. Die Figur 1 zeigt den Schwimmer 69 in der unteren Stellung. Ausgehend von dieser Stellung kann der Schwimmer 69 mit dem Hub H1 durch die Auftriebskraft der Luftkammer 26 angehoben werden.On the valve housing 2, a float 69 is mounted, which forms an air chamber 26 and a water chamber 27 in a housing 25. These two chambers 26 and 27 are separated from each other by a bottom wall 32. In the air chamber 26 is always filled with cistern air and in the water chamber 27 always water. The air in the air chamber 26 causes a buoyancy force according to arrow 28 and the water in the water chamber 27 at a partial emptying of the cistern ( Fig. 5 ) a weight according to arrow 29. At the float 69, a rod 23 is fixed, which projects down into a chamber 70 of the valve housing 2. On the rod 23, a stop cam 24 is formed, which allows a maximum stroke H1. The FIG. 1 shows the float 69 in the lower position. Starting from this position, the float 69 can be lifted with the stroke H1 by the buoyancy force of the air chamber 26.

Am Schwimmer 69 ist ein Nocken 30 angebracht, mit dem der Schwimmer 69 gemäss Figur 1 bei leerem oder teilweise leerem Spülkasten 1 auf einer zweiarmigen ersten Klinke 8 lastet. Die Klinke 8 ist an dem Ventilgehäuseteil 2a schwenkbar mit dem Ventilgehäuse 2 verbunden und umgreift das Rohr 67 halbkreisförmig. An der Klinke 8 sind zwei Nocken 33 angebracht, die mit dem Hauptventilkörper 3 zusammenarbeiten. Dazu besitzt der Hauptventilkörper 3 an seiner Aussenseite zwei gegenüberliegende vertikal verlaufende Rippen 71 und 71' (Fig. 6), die einen oberen Rand 72 bzw. 72' aufweisen, an welchen jeweils ein Nocken 33 gemäss Figur 1 anliegt. In der in Figur 1 gezeigten Stellung der ersten Klinke 8 wird der Hauptventilkörper 3 in der gezeigten geschlossenen Stellung durch die beiden Nocken 33 verriegelt. Der Hauptventilkörper 3 kann somit nicht angehoben werden. Die gezeigte Stellung der ersten Klinke 8 wird in dieser Stellung durch das Gewicht des Schwimmers 69 gehalten. Ist der Spülkasten 1 gemäss Figur 2 mit Spülwasser 66 gefällt, so ist der Schwimmer 69 wie gezeigt in der obersten Stellung angehoben und damit die Klinke 8 vom Gewicht des Schwimmers 69 entlastet. Beim Entleeren des Spülkastens 1 sinkt der Schwimmer 69 wieder nach unten und lastet mit den Nocken 30 auf der ersten Klinke 8.At the float 69, a cam 30 is mounted, with the float 69 according to FIG. 1 with empty or partially empty cistern 1 on a two-armed first pawl 8 loads. The pawl 8 is pivotally connected to the valve housing part 2 a with the valve housing 2 and surrounds the tube 67 in a semicircle. At the pawl 8, two cams 33 are mounted, which cooperate with the main valve body 3. For this purpose, the main valve body 3 has on its outside two opposite vertical ribs 71 and 71 '( Fig. 6 ), which have an upper edge 72 or 72 ', on which in each case a cam 33 according to FIG. 1 is applied. In the in FIG. 1 shown position of the first pawl 8, the main valve body 3 is locked in the closed position shown by the two cams 33. The main valve body 3 can thus not be raised. The illustrated position of the first pawl 8 is held in this position by the weight of the float 69. Is the cistern 1 according FIG. 2 With flushing water 66 like, the float 69 is as shown in the raised to the highest position and thus the latch 8 relieved of the weight of the float 69. When emptying the cistern 1, the float 69 drops down again and loads with the cam 30 on the first pawl eighth

Am Hilfsventilkörper 7 ist eine zweite ebenfalls zweiarmige in den Richtungen des Doppelpfeils 65 verschwenkbare Klinke 9 gelagert, welche den Hilfsventilkörper 7 halbkreisförmig umgreift und mit diesem über ein Drehgelenk 38 verbunden ist. An zwei horizontalen Armen 39 der Klinke 9 ist jeweils ein Mitnehmer 40 bzw. 62 angeordnet, an dem eine Zugstange 41 bzw. 60 (Fig. 6) angreift. Die Mitnehmer 40 bzw. 62 bilden jeweils einen Zapfen, der in ein Langloch 42 der Zugstange 41 bzw. 60 eingreift. Die Zugstange 41 bzw. 60 kann mit einer hier nicht gezeigten Betätigungseinrichtung, beispielsweise mit einem Betätigungshebel in Richtung des Pfeiles 43 bzw. 63 angehoben werden. An einem nach unten gerichteten Arm 35 ist eine Schulter 36 angeordnet, die bei angehobenen Hilfsventilkörper 7 am Rand 72 bzw. 72' der Rippe 71 bzw. 71' anstelle der Nocken 33 aufliegt, wie die Figur 3 zeigt. Wird an der Zugstange 41 bzw. 60 gezogen, so übt diese auf die zweite Klinke 9 ein Drehmoment aus, welches bezüglich des Drehgelenkes 38 in Figur 1 im Gegenuhrzeigersinn wirkt. Durch dieses Drehmoment wird beim Anheben des Hilfsventilkörpers 7 die erste Klinke 8 im Gegenuhrzeigersinn um das Drehgelenk 37 gedreht und damit werden die beiden Nocken 33 vom Rand 72 weggeschoben. Bei angehobenem Hilfsventilkörper 7 ist damit der Hauptventilkörper 3 mit dem Hilfsventilkörper 7 verriegelt.At the auxiliary valve body 7, a second also two-armed in the directions of the double arrow 65 pivotable pawl 9 is mounted, which surrounds the auxiliary valve body 7 in a semicircular shape and is connected thereto via a rotary joint 38. On two horizontal arms 39 of the pawl 9, a respective driver 40 or 62 is arranged, on which a pull rod 41 or 60 (FIG. Fig. 6 ) attacks. The drivers 40 and 62 each form a pin which engages in a slot 42 of the tie rod 41 and 60, respectively. The drawbar 41 and 60 can be raised with an actuating device, not shown here, for example with an actuating lever in the direction of arrow 43 and 63, respectively. On a downwardly directed arm 35, a shoulder 36 is arranged, which rests with raised auxiliary valve body 7 at the edge 72 and 72 'of the rib 71 and 71' instead of the cam 33, as the FIG. 3 shows. Is pulled on the drawbar 41 and 60, so this exerts on the second pawl 9 a torque, which with respect to the rotary joint 38 in FIG. 1 counterclockwise acts. By this torque, the first pawl 8 is rotated counterclockwise about the pivot 37 during lifting of the auxiliary valve body 7 and thus the two cams 33 are pushed away from the edge 72. When the auxiliary valve body 7 is raised so that the main valve body 3 is locked to the auxiliary valve body 7.

Über der Entlastungskammer 4 ist eine weitere Kammer 73 angeordnet, die gemäss Figur 7 eine Öffnung 75 aufweist, welche mit einem Schieber 76 verschliessbar ist. In dieser Kammer 73 ist gemäss den Figuren 6 und 7 ein Schwimmer 50 angeordnet, der um ein Drehgelenk 53 schwenkbar am Ventilgehäuse 2 gelagert ist. Der Schwimmer 50 ist ein so genannter Kippschwimmer und besitzt eine untere Luftkammer 55 sowie eine obere Wasserkammer 58. Die Kammern 55 und 58 sind durch eine Bodenwandung 57 voneinander getrennt. Die Kammer 73 ist bei gefülltem Spülkasten gemäss Figur 2 mit Wasser gefüllt. Die Luft in der Luftkammer 55 bewirkt eine Auftriebskraft gemäss Pfeil 56 und das Wasser in der Wasserkammer 58 bei leerer Kammer 73 ein Gewicht gemäss dem Pfeil 59. Bei gefüllter Kammer 73 wirkt auf den Schwimmer 50 ein Drehmoment im Uhrzeigersinn gemäss Doppelpfeil 54.About the discharge chamber 4, a further chamber 73 is arranged according to FIG. 7 an opening 75 which is closable with a slide 76. In this chamber 73 is according to the FIGS. 6 and 7 a float 50 is arranged, which is mounted pivotably about a pivot joint 53 on the valve housing 2. The float 50 is a so-called Kippschwimmer and has a lower air chamber 55 and an upper water chamber 58. The chambers 55 and 58 are separated by a bottom wall 57 from each other. The chamber 73 is in filled cistern according FIG. 2 filled with water. The air in the air chamber 55 causes a buoyant force according to arrow 56 and the water in the water chamber 58 at empty chamber 73 a weight according to the Arrow 59. When filled chamber 73 acts on the float 50, a clockwise torque according to double arrow 54th

Am Schwimmer 50 sind eine nach vorne ragende Nase 51 und ein nach oben ragender Anschlagnocken 52 angeordnet. Der Anschlagnocken 52 arbeitet mit der zweiten Zugstange 60 zusammen. Diese Zugstange 60 ist für eine Vollspülung vorgesehen und kann in Richtung des Pfeiles 63 angehoben werden. Die zweite Zugstange 60 besitzt ein Langloch 61, in das der Mitnehmer 62 der zweiten Klinke 9 eingreift. Wird die Zugstange 60 in Richtung des Pfeiles 63 angehoben, so greift die Zugstange 60 am Mitnehmer 62 an und zieht damit den Hauptventilkörper 7 nach oben. Wie beim Anheben mit der Zugstange 41 wird auf die Klinke 9 gemäss Fig. 6 im Gegenuhrzeigersinn um das Drehgelenk 38 ein Drehmoment ausgeübt, durch welches die Klinke 8 verschwenkt wird. Die Klinke 8 liegt gleichzeitig auf der Rippe 71 und auf der zweiten gegenüberliegenden Rippe 71' auf. Die Rippe 71' besitzt ebenfalls einen oberen Rand 72', auf welcher die Klinke 8 aufliegt. Die erste Klinke 8 als auch die zweite Klinke 9 erstrecken sich somit bogenförmig um den Hilfsventilkörper 7. In der Figur 1 ist die eine Seite und in der Figur 6 die andere Seite sichtbar.At the float 50, a forwardly projecting nose 51 and an upwardly projecting stop cam 52 are arranged. The stop cam 52 cooperates with the second pull rod 60. This pull rod 60 is provided for a full flush and can be raised in the direction of arrow 63. The second pull rod 60 has a slot 61 into which the catch 62 of the second pawl 9 engages. If the pull rod 60 is raised in the direction of the arrow 63, the pull rod 60 engages the driver 62 and thus pulls the main valve body 7 upwards. As when lifting with the drawbar 41 is on the pawl 9 according to Fig. 6 counterclockwise about the pivot 38, a torque exerted by which the pawl 8 is pivoted. The pawl 8 rests simultaneously on the rib 71 and on the second opposing rib 71 '. The rib 71 'also has an upper edge 72' on which the pawl 8 rests. The first pawl 8 and the second pawl 9 thus extend arcuately around the auxiliary valve body 7. In the FIG. 1 is the one side and in the FIG. 6 the other side visible.

Wird die zweite Zugstange 60 angehoben, so wird gleichzeitig die am unteren Ende der zweiten Zugstange 60 angeformte Zunge 74 angehoben. In der Grundstellung liegt diese Zunge 74 gemäss Figur 6 am Anschlagnocken 52 an und verhindert damit ein Kippen des Schwimmers 50 um das Drehgelenk 53. Beim Anheben der zweiten Zugstange 60 wird die Zunge 74 gemäss Figur 7 über den Anschlagnocken 52 angehoben und damit wird der Schwimmer 50 frei und kann aufgrund des genannten Drehmomentes um das Drehgelenk 53 im Uhrzeigersinn schwenken. Dadurch gelangt die Nase 51 in Eingriff mit einer Ausnehmung 64 der Rippe 71'. Dies bewirkt eine Verriegelung des angehobenen Hauptventilkörpers 3. Der Schwimmer 50 bleibt in dieser Stellung solang sich in der Kammer 73 Wasser befindet und damit das genannte Drehmoment ausgeübt wird.If the second pull rod 60 is raised, the tongue 74 formed on the lower end of the second pull rod 60 is raised at the same time. In the basic position, this tongue 74 is according FIG. 6 on the stop cam 52 and thus prevents tilting of the float 50 about the pivot 53. When lifting the second pull rod 60, the tongue 74 is according to FIG. 7 raised above the stop cam 52 and thus the float 50 is free and can pivot about the pivot 53 in a clockwise direction due to said torque. As a result, the nose 51 engages with a recess 64 of the rib 71 '. This causes a locking of the raised main valve body 3. The float 50 remains in this position as long as there is water in the chamber 73 and thus said torque is applied.

Das Ausfliessen des Wassers aus der Kammer 73 kann mit dem in Figur 7 gezeigten Schieber 76 reguliert werden. Dieser Schieber 76 befindet sich vor der Öffnung 75 und kann in den Richtungen des Doppelpfeiles 77 verschoben werden. Ist der Schieber 76 in der in Figur 7 gezeigten Stellung, so ist die Öffnung 75 geschlossen. Sinkt das Niveau des Spülwassers 66 unterhalb das Niveau der Öffnung 75, so bleibt das Wasser in der Kammer 73 bis der Spülkasten 2 im Wesentlichen entleert ist. Bei angehobenem Schieber 76 entleert sich die Kammer 73 jedoch vergleichsweise schnell, so dass die Kammer 73 geleert ist, bevor der Spülkasten 1 entleert ist. Ist die Kammer 73 entleert, so ist das genannte Drehmoment nicht mehr vorhanden und der Schwimmer 50 kippt aufgrund seines Gewichtes sofort in die in Figur 6 gezeigte Stellung. Der Hauptventilkörper 3 wird dadurch frei und fällt aufgrund seines Eigengewichtes sofort auf den Ventilsitz 13, womit das Hauptventil V geschlossen wird. Der Hilfsventilkörper 7 wird vorzeitig entriegelt und fällt ebenfalls aufgrund seines Gewichtes nach unten und schliesst damit das erste Hilfsventil HV1. Am Schieber 76 kann damit die Vollmenge bei einer Spülung reguliert werden. Beispielsweise kann die Vollmenge auf sechs Liter oder neun Liter eingestellt werden. Es handelt sich hier um eine Voreinstellung, die nach der Installation des Spülkastens 1 in der Regel nicht verändert wird. Der Spülkasten 1 wird somit für eine Vollspülung mit beispielsweise neun Litern oder für eine Vollspülung mit sechs Litern installiert.The outflow of water from the chamber 73 can with the in FIG. 7 shown slider 76 are regulated. This slider 76 is located in front of the opening 75 and can be moved in the directions of the double arrow 77. If the slider 76 is in the in FIG. 7 shown position, the opening 75 is closed. If the level of the rinse water 66 drops below the level of the opening 75, the water in the chamber 73 remains until the cistern 2 is substantially emptied. With the slide 76 raised, however, the chamber 73 empties relatively quickly, so that the chamber 73 is emptied before the cistern 1 is emptied. If the chamber 73 is emptied, the said torque is no longer present and the float 50 tilts due to its weight immediately in the FIG. 6 shown position. The main valve body 3 is thereby released and falls due to its own weight immediately on the valve seat 13, whereby the main valve V is closed. The auxiliary valve body 7 is unlocked prematurely and also falls due to its weight down and thus closes the first auxiliary valve HV1. On the slider 76 so that the full amount can be regulated at a flush. For example, the full amount can be set to six liters or nine liters. This is a default setting, which is usually not changed after the installation of the cistern 1. The cistern 1 is thus installed for a full flush with, for example, nine liters or for a full flush with six liters.

Nachfolgend wird die Wirkungsweise des erfindungsgemässen Ablaufventils 10 näher erläutert.The operation of the inventive drain valve 10 will be explained in more detail.

Vor der Auslösung einer Spülung ist der Spülkasten 1 mit Spülwasser 66 gemäss Figur 2 gefüllt. Durch den Auftrieb des Wassers ist der Schwimmer 69 angehoben. Der Hauptventilkörper 3 ist in der geschlossenen Stellung vom Wasser 66 belastet. Die Entlastungskammer 4 ist ebenfalls mit Wasser gefüllt, das ebenfalls auf dem Hauptventilkörper 3 lastet.Before triggering a flush cistern 1 with flushing water 66 is according to FIG. 2 filled. Due to the buoyancy of the water, the float 69 is raised. The main valve body 3 is loaded in the closed position by the water 66. The discharge chamber 4 is also filled with water, which also rests on the main valve body 3.

Zur Auslösung einer Teilspülung mit beispielsweise drei Litern Wasser wird die Zugstange 41 in Richtung des Pfeils 43 angehoben. Die vergleichsweise kleine Kraft zum Anheben der Zugstange 41 kann mit Handkraft oder mit einem nicht gezeigten Motor erfolgen. Durch Anheben der Zugstange 41 wird der Hilfsventilkörper 7 angehoben und schliesslich wird in der angehobenen Stellung gemäss Figur 3 die erste Klinke 8 durch eine Schwenkbewegung der zweiten Klinke 9 verschwenkt. Der Hilfsventilkörper 7 ist damit mit dem Hauptventilkörper 3 verriegelt und gleichzeitig wird die Verriegelung des Hauptventilkörpers 3 zum Ventilgehäuse 2 aufgehoben. Beim genannten Anheben des Hilfsventilkörpers 7 wird das erste Hilfsventil HV1 geöffnet und unmittelbar danach mit dem gleichen Hub das zweite Hilfsventil HV2 geschlossen. Ist das erste Hilfsventil HV1 geöffnet, so strömt gemäss Figur 3 in Richtung des Pfeiles 47 Wasser aus der Entlastungskammer 4 nach unten in den Auslaufstutzen 12. Dadurch entsteht ein Differenzdruck am Hauptventilkörper 3, der nach oben in die in Figur 4 gezeigte Stellung gefahren wird. Dadurch wird das Hauptventil V geöffnet und das Wasser 66 strömt gemäss Figur 4 durch die Öffnungen 15 in Richtung, der Pfeile 48 aus dem Spülkasten 1 in die WC-Schüssel.To trigger a partial flush with, for example, three liters of water, the pull rod 41 is raised in the direction of arrow 43. The comparatively small force for lifting the drawbar 41 can be done by hand or with a motor, not shown. By raising the drawbar 41 of the auxiliary valve body 7 is raised and finally in accordance with the raised position FIG. 3 the first pawl 8 is pivoted by a pivoting movement of the second pawl 9. The auxiliary valve body 7 is thus locked with the main valve body 3 and at the same time the locking of the main valve body 3 is lifted to the valve housing 2. During said raising of the auxiliary valve body 7, the first auxiliary valve HV1 is opened and immediately thereafter the second auxiliary valve HV2 is closed with the same stroke. If the first auxiliary valve HV1 is open, then flows according to FIG. 3 in the direction of arrow 47 water from the discharge chamber 4 down into the outlet pipe 12. This creates a differential pressure on the main valve body 3, the up in the in FIG. 4 shown position is driven. As a result, the main valve V is opened and the water 66 flows according to FIG. 4 through the openings 15 in the direction of the arrows 48 from the cistern 1 in the toilet bowl.

Beim Anheben des Hauptventilkörpers 3 geht der Hilfsventilkörper 7 gleichzeitig mit, da er wie erwähnt mit dem Hauptventilkörper 3 durch die zweite Klinke 9 verriegelt ist. Da das Spülwasser 66 aus dem Spülkasten 1 herausfliesst, sinkt entsprechend die Wasseroberfläche 46. Erreicht diese Wasseroberfläche 46 den Schwimmer 69, so nimmt nachfolgend der Auftrieb des Schwimmers 69 ab und dieser sinkt entsprechend nach unten. Schliesslich drückt der Nocken 31 auf die zweite Klinke 9 und schwenkt diese im Uhrzeigersinn in die in Figur 5 gezeigte Stellung. Der Nocken 30 liegt nun an der ersten Klinke 8 an und drückt diesen gegen die Rippen 71 bzw. 71'. Der Hilfsventilkörper 7 ist nun entriegelt und fällt sofort aufgrund seines Eigengewichtes auf den Ventilsitz 18. Dadurch wird das erste Hilfsventil HV1 geschlossen. Durch eine obere Öffnung 45 des Kanals 6 fliesst von oben gemäss Figur 5 in Richtung des Pfeiles 49 Spülwasser 66 in die Steueröffnung 20 und schliesslich in die Entlastungskammer 4. Dieses Wasser lastet auf dem Hauptventilkörper 3, der dadurch sofort nach unten auf den Ventilsitz 13 fällt. Dadurch wird das Hauptventil V geschlossen. Der Spülkasten 1 ist jedoch erst teilweise entleert, da sich die Wasseroberfläche 46 erst bis etwa in den Bereich des Schwimmers 69 gesenkt hat. Im Spülkasten 1 verbleiben somit beispielsweise noch sechs Liter Spülwasser. Befindet sich der Hauptventilkörper 3 auf dem Ventilsitz 13, so befindet sich auch der Hilfsventilkörper 7 in der in Figur 2 gezeigten unteren Stellung. Durch den Druck des Schwimmers 69 auf die erste Klinke 8 wird diese Klinke 8 wieder in die in Figur 2 gezeigte Stellung verschwenkt, in welcher der Hauptventilkörper 3 mit dem Ventilgehäuse 2 verriegelt ist. Mit dem Sinken der Wasseroberfläche 46 wird ein hier nicht gezeigtes an sich übliches Einlaufventil geöffnet und damit strömt Spülwasser in den Spülkasten 1 und dieser wird schliesslich wieder nachgefüllt, bis die Wasseroberfläche 46 etwa das in Figur 2 gezeigte Niveau erreicht. Der Spülkasten 1 ist damit wieder in der in Figur 2 gezeigten Ausgangsstellung und damit für eine weitere Spülung bereit.When lifting the main valve body 3, the auxiliary valve body 7 is at the same time, since it is locked as mentioned with the main valve body 3 by the second pawl 9. Since the rinse water 66 flows out of the cistern 1, the water surface 46 correspondingly decreases. If this water surface 46 reaches the float 69, the buoyancy of the float 69 subsequently decreases and the latter sinks accordingly. Finally, the cam presses 31 on the second pawl 9 and pivots it in the clockwise direction in the FIG. 5 shown position. The cam 30 is now against the first pawl 8 and presses it against the ribs 71 and 71 '. The auxiliary valve body 7 is now unlocked and falls immediately due to its own weight on the valve seat 18. As a result, the first auxiliary valve HV1 is closed. Through an upper opening 45 of the channel 6 flows from above according to FIG. 5 in the direction of arrow 49 rinse water 66 in the control port 20 and finally in the discharge chamber 4. This water rests on the main valve body 3, which thereby immediately falls down on the valve seat 13. As a result, the main valve V is closed. However, the cistern 1 is only partially emptied, since the water surface 46 has lowered until approximately in the area of the float 69. In the cistern 1 thus remain, for example, still six liters of rinse water. The main valve body 3 is located on the valve seat 13, so is the auxiliary valve body 7 in the in FIG. 2 shown lower position. By the pressure of the float 69 on the first pawl 8, this pawl 8 is again in the in FIG. 2 shown pivoted position in which the main valve body 3 is locked to the valve housing 2. With the sinking of the water surface 46 is not one here shown per se conventional inlet valve open and thus rinse water flows into the cistern 1 and this is finally refilled until the water surface 46 is about the in FIG. 2 achieved level reached. The cistern 1 is thus back in the in FIG. 2 shown starting position and thus ready for further flushing.

Für die Auslösung einer Vollspülung wird die zweite Zugstange 60 gemäss Figur 6 in Richtung des Pfeiles 63 angehoben. Die Spülung wird damit wie oben erläutert ausgelöst, da auch in diesem Fall der Hauptventilkörper 7 angehoben und damit das erste Hilfsventil HV1 geöffnet und das zweite Hilfsventil HV2 geschlossen wird. Etwa gleichzeitig wird aber der Schwimmer 50 entriegelt und dieser kippt nun in Figur 6 im Uhrzeigersinn um die Achse des Drehgelenks 53. Ist der Hauptventilkörper 3 um den Hub H2 (Fig. 6) angehoben, kippt der Schwimmer 50 weiter in gleicher Drehrichtung und die Nase 51 greift schliesslich in die Ausnehmung 64 ein, wie dies in Figur 7 gezeigt ist. Der Hauptventilkörper 3 ist nun mit dem Ventilgehäuse 2 verriegelt. Der nach der Spülauslösung sinkende Schwimmer 69 schliesst wie bei einer Teilspülung das Hilfsventil HV1 bleibt aber wirkungslos und kann die Spülung nicht unterbrechen. Ist der Schieber 76 angehoben und damit die Öffnung 75 frei, so wird der Schwimmer 50 wie oben erläutert vor einer vollständigen Entleerung des Spülkastens 1 wieder in die in Figur 6 gezeigte Stellung verschwenkt und die Verriegelung des Hauptventilkörpers 3 aufgehoben und damit die Spülung unterbrochen. In diesem Fall wird ebenfalls eine Vollspülung ausgeführt, jedoch lediglich mit sechs statt beispielsweise neun Litern Spülwasser 66.

The purge is thus triggered as explained above, since in this case the main valve body 7 is raised and thus the first auxiliary valve HV1 is opened and the second auxiliary valve HV2 is closed. At about the same time but the float 50 is unlocked and this now tilts in FIG. 6 clockwise about the axis of the pivot 53. Is the main valve body 3 to the stroke H2 ( Fig. 6 ), the float 50 tilts further in the same direction of rotation and the nose 51 finally engages in the recess 64, as in FIG. 7 is shown. The main valve body 3 is now locked to the valve housing 2. The swimmer 69, which sinks after the rinsing release, closes the auxiliary valve HV1 as in the case of a partial rinse, but remains ineffective and can not interrupt the rinsing. If the slider 76 is raised and thus the opening 75 free, the float 50 is as explained above before a complete emptying of the cistern 1 back into the in FIG. 6 shown pivoted position and lifted the lock of the main valve body 3, thus interrupting the flushing. In this case, a full flush is also carried out, but only with six instead of, for example, nine liters of rinse water 66th <B> LIST OF REFERENCES </ b> 1 cistern 29 arrow 2 valve housing 30 cam 2a Valve housing part 31 cam 3 Main valve body 32 bottom wall 4 relief chamber 33 cam 5 Ventilöfnung 34 edge 6 Channel (valve opening) 35 poor 7 Auxiliary valve body 36 shoulder 8th first latch 37 swivel 9 second latch 38 swivel 0 drain valve 39 poor 1 Spülkastenboden 40 takeaway 12 outlet connection 41 pull bar 13 valve seat 42 Long hole 14 valve disc 43 arrow 15 opening 44 top 16 piston ring 45 opening 17 inside 46 water surface 18 valve seat 47 arrow 19 valve disc 48 arrow 20 control port 49 arrow 21 valve seat 50 swimmer 22 Überlauflcanal 51 nose 23 Rod 52 stop cams 24 stop cams 53 swivel 25 casing 54 double arrow 26 air chamber 55 air chamber 27 water chamber 56 arrow 28 arrow 57 bottom wall 58 water chamber 72 edge 59 arrow 73 chamber 60 second pull rod 74 tongue 61 Long hole 75 opening 62 takeaway 76 pusher 63 arrow 77 double arrow 64 recess H1 stroke 65 double arrow H2 stroke 66 dishwater H3 stroke 67 pipe HV 1 first auxiliary valve 68 opening HV2 second auxiliary valve 69 swimmer V main valve 70 chamber 71 rib
