Description

TECHNISCHES GEBIETTECHNICAL AREA

Die vorliegende Erfindung betrifft eine Ablaufgarnitur für einen Spülkasten nach Anspruch 1.The present invention relates to a drain fitting for a cistern according to claim 1.

STAND DER TECHNIKSTATE OF THE ART

Aus dem Stand der Technik sind Ablaufgarnituren für Spülkästen bekannt geworden. Beispielsweise offenbart die EP 0 890 680 eine Ablaufgarnitur, welche mit einem Pneumatikheber betrieben wird. Auch die DE 298 08 200 U1 sowie die EP 2 865 817 A1 zeigen gattungsgemäße Ablaufgarnituren.Drain fittings for cisterns have become known from the prior art. For example, the EP 0 890 680 a drain fitting, which is operated with a pneumatic jack. Also the DE 298 08 200 U1 as well as the EP 2 865 817 A1 show generic drain sets.

DARSTELLUNG DER ERFINDUNGPRESENTATION OF THE INVENTION

Ausgehend vom vorliegenden Stand der Technik ist es eine bevorzugte Aufgabe der vorliegenden Erfindung eine Ablaufgarnitur anzugeben, welche unter einer Betätigung mit einem fluidisch oder elektrisch ansteuerbaren Aktuator für eine Teilmengenspülung einen möglichst grossen Einstellbereich aufweist und dennoch kompakt ausgebildet ist.Starting from the present state of the art, it is a preferred object of the present invention to provide a drain fitting which, when actuated with a fluidically or electrically controllable actuator for partial flushing, has the largest possible setting range and is nevertheless designed to be compact.

Diese Aufgabe löst der Gegenstand nach Anspruch 1. Demgemäss umfasst eine Ablaufgarnitur für einen Spülkasten, ein Gehäuse mit einer Gehäusewand, die aussenseitig eine Mantelfläche aufweist, und ein im Gehäuse bewegbar gelagerten Ventilkörper mit einem Schwimmer, wobei der Ventilkörper entlang einer Mittelachse von einer Ruhelage in eine Spüllage und von der Spüllage in die Ruhelage bewegbar ist. Der Schwimmer ist innerhalb einer durch das Gehäuse begrenzten Schwimmerkammer entlang der Mittelachse bewegbar und arbeitet mit der Schwimmerkammer hydraulisch zusammen. Die Schwimmerkammer umfasst mindestens einen Steuerungsdurchgang für die Steuerung einer ersten Spülmenge, durch welchen, sobald ein die Ablaufgarnitur umgebender Spülwasserspiegel auf die Höhe des Steuerungsdurchgangs abgesunken ist, Luft von Bereichen ausserhalb der Schwimmerkammer in die Schwimmerkammer eintreten kann, derart, dass die Druckverhältnisse zwischen der Schwimmerkammer und den Bereichen ausserhalb der Schwimmerkammer ausgleichbar sind, wobei der Schwimmer bei Ausgleich der Druckverhältnisse von der Spüllage in die Ruhelage bewegbar ist. Die Ablaufgarnitur umfasst weiterhin eine Steuerungseinheit mit einem Schliessgewicht für die Steuerung einer zweiten Spülmenge, wobei das Schliessgewicht bei Auslösung der zweiten Spülmenge eine Schliesskraft auf den Ventilkörper bewirkt und wobei das Schliessgewicht ausserhalb des Gehäuses seitlich zur Mantelfläche und relativ zur Mantelfläche bewegbar angeordnet ist. Das Schliessgewicht ist in seiner Höhenlage einstellbar ausgebildet. Aufgrund dieser Einstellung lässt sich die Menge der zweiten Spülmenge einstellen. Weiter umfasst die Ablaufgarnitur einen fluidisch oder elektrisch ansteuerbaren Aktuator, mit welchem der Ventilkörper von der Ruhelage in die Spüllage anhebbar ist. Der Aktuator ist seitlich zur Mantelfläche und bezüglich der Mittelachse gesehen gegenüber des ausserhalb des Gehäuses angeordneten Schliessgewichtes angeordnet.This object is achieved by the subject matter of claim 1. Accordingly, it includes a drain fitting for a cistern, a housing with a housing wall which has an outer surface on the outside, and a valve body movably mounted in the housing with a float, the valve body moving from a rest position along a central axis a flushing position and is movable from the flushing position to the rest position. The float can be moved along the central axis within a float chamber defined by the housing and works hydraulically with the float chamber. The float chamber comprises at least one control passage for the control of a first flushing amount, through which, as soon as a flushing water level surrounding the drain fitting has dropped to the level of the control passage, air from Areas outside the float chamber can enter the float chamber in such a way that the pressure conditions between the float chamber and the areas outside the float chamber can be equalized, the float being able to move from the flushing position into the rest position when the pressure conditions are equalized. The drain fitting further comprises a control unit with a closing weight for controlling a second flushing quantity, the closing weight causing a closing force on the valve body when the second flushing quantity is triggered, and the closing weight being arranged to be movable outside of the housing laterally to the outer surface and relative to the outer surface. The height of the closing weight is adjustable. Based on this setting, the amount of the second flush amount can be set. Furthermore, the drain fitting comprises a fluidically or electrically controllable actuator with which the valve body can be raised from the rest position to the flushing position. The actuator is arranged to the side of the lateral surface and, viewed with respect to the central axis, opposite the closing weight arranged outside the housing.

Mit anderen Worten heisst dies, dass die ausserhalb des Gehäuses liegenden Elemente, nämlich der Aktuator und das Schliessgewicht bezüglich der Mittelachse gegenübereinander liegen. Das Schliessgewicht liegt dabei auf einer Seite des Gehäuses und der Aktuator liegt auf der anderen Seite des Gehäuses. Hierdurch wird erreicht, dass die Höhenlage des Schliessgewichtes ohne Kollision mit dem Aktuator eingestellt werden kann. Der Einstellbereich des Schliessgewichtes wird also nach oben hin vergrössert.In other words, this means that the elements lying outside the housing, namely the actuator and the closing weight, lie opposite one another with respect to the central axis. The closing weight is on one side of the housing and the actuator is on the other side of the housing. This ensures that the height of the closing weight can be adjusted without colliding with the actuator. The adjustment range of the closing weight is thus increased upwards.

Vorzugsweise liegen der Aktuator und das Schliessgewicht bezüglich der Mittelachse bzw. des Gehäuses diametral bzw. entgegengesetzt gegenübereinander.The actuator and the closing weight are preferably diametrically opposed to one another with respect to the central axis or the housing.

Die Funktion des Schliessgewichts ist dahingehend definiert, dass dessen Auftrieb im Wasser bei sich unterhalb des Schliessgewichtes absenkenden Wasserstand wegfällt und die volle Gewichtskraft auf den Ventilkörper wirkt. Das Schliessgewicht ist dabei bei entsprechender Betätigung mit dem Ventilkörper derart in Verbindung, dass die Gewichtskraft auf den Ventilkörper übertragen werden kann. Vorzugsweise ist das Schliessgewicht temporär mit dem Ventilkörper verbindbar.The function of the closing weight is defined in such a way that its buoyancy in the water disappears when the water level drops below the closing weight and the full weight acts on the valve body. The closing weight is in connection with appropriate actuation with the valve body in such a way that the weight can be transmitted to the valve body. The closing weight can preferably be temporarily connected to the valve body.

Besonders bevorzugt weist die Mantelfläche in dem Bereich, in welchem der Aktuator zu liegen kommt, eine leichte Einbuchtung auf, so dass die Kompaktheit weiter erhöht werden kann.The lateral surface particularly preferably points in the area in which the actuator is facing there is a slight indentation, so that the compactness can be further increased.

Vorzugsweise liegen der Aktuator und das Schliessgewicht ausschliesslich zwischen zwei parallel zueinander liegenden Begrenzungsebenen, welche Begrenzungsebenen parallel zur Mittelachse und durch die maximale Ausdehnung der die Schwimmerkammer begrenzende Mantelfläche verlaufen. Mit anderen Worten kann gesagt werden, dass bei Betrachtung der Ablaufgarnitur von oben in Richtung der Mittelachse gesehen zwei beabstandete und rechtwinklig zur Mittelachse orientierte Geraden definiert sind, die durch die maximale Ausdehnung der die Schwimmerkammer begrenzende Mantelfläche verlaufen, wobei der Aktuator und das Schliessgewicht ausschliesslich zwischen den beiden Geraden liegt.The actuator and the closing weight are preferably located exclusively between two boundary planes lying parallel to one another, which boundary planes run parallel to the central axis and through the maximum extent of the lateral surface delimiting the float chamber. In other words, it can be said that when looking at the drain fitting viewed from above in the direction of the central axis, two straight lines are defined that are spaced apart and oriented at right angles to the central axis and that run through the maximum extent of the lateral surface delimiting the float chamber, with the actuator and the closing weight exclusively between the two straight lines.

Hierdurch kann eine Ablaufgarnitur angegeben werden, welche gut in einen Spülkasten passt. Das heisst, bezüglich der Breite des Spülkastens gesehen stehen keine Elemente der Ablaufgarnitur weiter vor als ein Mass, welches durch die maximale Ausdehnung der Schwimmerkammer vorgegeben ist.This allows a drain fitting to be specified that fits well in a cistern. That means, with regard to the width of the cistern, no elements of the drain fitting protrude beyond a dimension which is predetermined by the maximum expansion of the float chamber.

Vorzugsweise ist der Aktuator ausschliesslich zum Anheben des Ventilkörpers, nicht aber für das Halten des Ventilkörpers in der Spüllage ausgebildet, wobei der Ventilkörper aufgrund des hydraulischen Gleichgewichtes in der Schwimmerkammer in der Spüllage gehalten wird. Die Bewegung von der Spüllage in die Verschlusslage wird entweder durch den Lufteintritt in die Schwimmerkammer oder durch das Wirken der Steuerungseinheit mit dem Schliessgewicht erreicht.The actuator is preferably designed exclusively for lifting the valve body, but not for holding the valve body in the flushing position, the valve body being held in the flushing position due to the hydraulic balance in the float chamber. The movement from the flushing position into the closed position is achieved either through the air inlet into the float chamber or through the action of the control unit with the closing weight.

Hierdurch ergehen die Vorteile, dass die Bewegung des Aktautors zeitlich nicht gesteuert werden muss, sondern bei Auslösung der Spülung der Aktuator betätigt wird und dann in Ruhelage zurückkehrt bzw., dass die Ablaufgarnitur als solche auch bei einem Ausfall des Aktautors von der Spüllage in die Verschlusslage bewegt werden kann. Darüber hinaus ergeht der Vorteil, dass die Ablaufgarnitur als solche, also auch ohne den Aktuator betrieben werden kann. Besonders bevorzug weist die Ablaufgarnitur diesbezüglich am Ventilkörper und/oder an der Steuerungseinheit Zugelemente, wie Zugbügel auf, über welche der Ventilkörper angehoben werden kann.This has the advantages that the movement of the actuator does not have to be controlled in time, but rather that the actuator is actuated when the flush is triggered and then returns to the rest position, or that the drain fitting as such also moves from the flush position to the closed position even if the actuator fails can be moved. In addition, there is the advantage that the waste set can be operated as such, that is, even without the actuator. In this regard, the drain fitting particularly preferably has tension elements, such as tension brackets, on the valve body and / or on the control unit, by means of which the valve body can be raised.

Vorzugsweise wirkt der Aktuator für die erste Spülmenge direkt auf den Ventilkörper, welcher direkt durch den Aktuator anhebbar ist. Weiter wirkt der Aktuator für die zweite Spülmenge indirekt über die Steuerungseinheit auf den Ventilkörper, welcher indirekt durch den Aktuator über die Steuerungseinheit anhebbar ist. Mit dem Anheben der Steuerungseinheit werden zugleich der Ventilkörper und das Schliessgewicht angehoben.The actuator for the first flushing quantity preferably acts directly on the valve body, which can be raised directly by the actuator. Furthermore, the actuator for the second flushing quantity acts indirectly via the control unit on the valve body, which can be raised indirectly by the actuator via the control unit. When the control unit is raised, the valve body and the closing weight are raised at the same time.

Vorzugsweise ist das Schliessgewicht bei Betätigung entlang der Mantelfläche in Richtung der Mittelachse über einen Bewegungsbereich von einer Ruhelage in eine Spüllage bewegbar, wobei der Bewegungsbereich des Schliessgewichtes sich vorzugsweise in eine Höhenlage erstreckt, in welcher der Aktuator liegt, derart, dass das Schliessgewicht auf eine Höhenlage, in welcher der Aktuator liegt, bewegbar ist.The closing weight can preferably be moved in the direction of the central axis over a range of motion from a rest position to a flushing position when actuated along the circumferential surface, the range of motion of the closing weight preferably extending to a height at which the actuator lies, such that the closing weight is at a height , in which the actuator is located, is movable.

Der Bewegungsbereich ragt also bis in die Höhenlage des Aktuators ein. Gerade in diesem Zusammenhang ist die erfindungsgemässe Anordnung von Vorteil, weil es zu einer Kollision mit dem Aktuator kommen kann.The range of motion therefore extends up to the height of the actuator. The arrangement according to the invention is particularly advantageous in this context because it can lead to a collision with the actuator.

Vorzugsweise ist das Schliessgewicht in seiner Höhe über einen Einstellbereich einstellbar ausgebildet, wobei der Einstellbereich des Schliessgewichtes sich vorzugsweise in eine Höhenlage erstreckt, in welcher der Aktuator liegt, derart, dass das Schliessgewicht auf eine Höhenlage, in welcher der Aktuator liegt, schiebbar ist. Auch in diesem Zusammenhang ist die erfindungsgemässe Anordnung von Vorteil, weil der Einstellbereich massiv grösser wird und insbesondere sich auch auf eine Höhe erstreckt, in welcher der Aktuator liegt. Je höher oben das Schliessgewicht liegt, desto weniger Wasser wird aus dem Spülkasten entnommen. Der Einstellbereich erstreckt sich vorzugsweise entlang der Mantelfläche nach unten hin bis auf die Höhe der Schwimmerkammer insbesondere bis mindestens auf einen Höhenbereich, in welchem der oberste Steuerungsdurchgang liegt.The height of the closing weight is preferably adjustable over an adjustment range, the adjustment range of the closing weight preferably extending to an altitude in which the actuator lies, such that the closing weight can be pushed to an altitude in which the actuator lies. The arrangement according to the invention is also advantageous in this context because the setting range becomes massively larger and in particular also extends to a height at which the actuator lies. The higher the closing weight, the less water is removed from the cistern. The adjustment range preferably extends downward along the lateral surface to the height of the float chamber, in particular to at least one height range in which the uppermost control passage lies.

Vorzugsweise umfasst die Steuerungseinheit weiterhin eine Lagerstange, welche ausserhalb des Gehäuses angeordnet ist, wobei das Schliessgewicht an der Lagerstange fest oder relativ zur Lagerstange einstellbar gelagert ist. Die Lagerstange erstreckt sich vorzugsweise von einer Höhenlage, in welcher der Aktuator liegt nach unten in Richtung der Schwimmerkammer, insbesondere auf eine Höhenlage unterhalb des obersten Steuerungsdurchgangs. Die Lagerstange liegt auf der gleichen Seite wie das Schliessgewicht, nämlich bezüglich der Mittelachse diametral bzw. gegenüber vom Aktuator.The control unit preferably further comprises a bearing rod, which is arranged outside the housing, the closing weight being mounted fixedly on the bearing rod or being adjustable relative to the bearing rod. The bearing rod preferably extends from a height position in which the actuator lies downwards in the direction of the float chamber, in particular to a height position below the uppermost control passage. The bearing rod is on the same side as that Closing weight, namely diametrically with respect to the central axis or opposite the actuator.

Vorzugsweise ist das Schliessgewicht über ein Schaltorgan dem Ventilkörper mechanisch zuschaltbar, wobei das Schaltorgan beim Anheben der Steuerungseinheit selbsttätig mit dem Ventilkörper eine Rastverbindung eingeht. Das Schliessgewicht stellt bei Erreichen eines für die zweite Spülmenge vorgesehenen Wasserstandes eine Schliesskraft auf den Ventilkörper bereit, welche Schliesskraft über das Zuschalten über das Schaltorgan zum Ventilkörper auf den Ventilkörper aufgebracht wird.The closing weight can preferably be mechanically connected to the valve body via a switching element, the switching element automatically engaging with the valve body when the control unit is raised. When a water level provided for the second flush volume is reached, the closing weight provides a closing force on the valve body, which closing force is applied to the valve body by switching on to the valve body via the switching element.

Vorzugsweise ist das Schaltorgan an der Lagerstange gelagert.The switching element is preferably mounted on the bearing rod.

Vorzugsweise wird die Lagerstange durch den Aktuator angehoben, während die Lagerstange mit einem Mitnehmer auf den Ventilkörper wirkt und diesen ebenfalls anhebt.The bearing rod is preferably raised by the actuator, while the bearing rod acts with a driver on the valve body and also lifts it.

Vorzugsweise weist der Aktuator einen ersten Aktuatorhebel und einen zweiten Aktuatorhebel auf, wobei der erste Aktuatorhebel auf den Ventilkörper wirkt und wobei der zweite Aktuatorhebel auf die Steuerungseinheit, insbesondere auf die Lagerstange, wirkt.The actuator preferably has a first actuator lever and a second actuator lever, the first actuator lever acting on the valve body and the second actuator lever acting on the control unit, in particular on the bearing rod.

Vorzugsweise ist der Hub des ersten Aktuatorhebels unterschiedlich zum Hub des zweiten Aktuatorhebels.The stroke of the first actuator lever is preferably different from the stroke of the second actuator lever.

Vorzugsweise ist die Verbindung zwischen dem Aktuatorhebel und dem Ventilkörper bzw. der Steuerungseinheit derart, dass der Ventilkörper bzw. die Steuerungseinheit auch ohne Betätigung des Aktuatorhebels anhebbar ist. Besonders bevorzugt weisen der Ventilkörper bzw. die Steuerungseinheit, insbesondere die Stange, jeweils einen entsprechenden Absatz auf, an welchen der entsprechende Aktuatorhebel von unten her angreift.The connection between the actuator lever and the valve body or the control unit is preferably such that the valve body or the control unit can be raised even without actuating the actuator lever. Particularly preferably, the valve body or the control unit, in particular the rod, each have a corresponding shoulder, on which the corresponding actuator lever acts from below.

Vorzugsweise ist der Aktuator ein pneumatischer Aktuator mit zwei übereinander angeordneten Kolben, insbesondere Hubkolben, oder mit mindestens einem Faltenbalg. Vorzugsweise ist jeder Kolben mit je einem Aktuatorhebel in Kontakt.The actuator is preferably a pneumatic actuator with two pistons arranged one above the other, in particular reciprocating pistons, or with at least one bellows. Each piston is preferably in contact with an actuator lever.

Vorzugsweise sind die Kolben entlang einer gemeinsamen Kolbenachse bewegbar, wobei die Kolbenachse parallel zur Mittelachse verläuft. Vorzugsweise ist die Kolbenachse möglichst nah an der Mittelachse, das heisst in einem geringen Abstand, so dass die Baugrösse verkleinert wird.The pistons can preferably be moved along a common piston axis, the piston axis running parallel to the central axis. The piston axis is preferably as close as possible to the central axis, that is to say at a short distance, so that the size is reduced.

Vorzugsweise weist die Mantelfläche mindestens ein Aufnahmeelement auf und der Aktuator weist mindestens ein Rastelement auf, wobei das Rastelement in das Aufnahmeelement eingreift, derart, dass der Aktuator mit dem Gehäuse über eine Rastverbindung verbindbar ist. Das Aufnahmeelement ist vorzugsweise integral an der Mantelfläche angeformt. Vorzugsweise liegt das Aufnahmeelement oberhalb der Schwimmerkammer.The lateral surface preferably has at least one receiving element and the actuator has at least one latching element, the latching element engaging in the receiving element in such a way that the actuator can be connected to the housing via a latching connection. The receiving element is preferably integrally formed on the outer surface. The receiving element is preferably located above the float chamber.

Vorzugsweise liegt der Aktuator ausschliesslich oberhalb der Schwimmerkammer bzw. oberhalb des obersten Steuerungsdurchgangs. Diese Anordnung ist vorteilhaft, weil unterhalb des Aktuators der Querschnitt der Schwimmerkammer sich seitlich zur Mittelachse gesehen in Bereiche unterhalb des Aktautors erstrecken können.The actuator is preferably located exclusively above the float chamber or above the uppermost control passage. This arrangement is advantageous because, below the actuator, the cross section of the float chamber, viewed laterally to the central axis, can extend into areas below the actuator.

Vorzugsweise ist die erste Spülung eine Vollmengenspülung und die zweite Spülung eine Teilmengenspülung; oder die erste Spülung ist eine Teilmengenspülung und die zweite Spülung eine Vollmengenspülung.The first rinse is preferably a full-quantity rinse and the second rinse is a partial-quantity rinse; or the first flush is a partial flush and the second flush is a full flush.

Vorzugsweise sind mehrere Steuerungsdurchgänge auf verschiedenen Höhenlagen angeordnet, wobei die Ablaufgarnitur weiterhin mindestens ein Verschlusselement umfasst, mit welchem einer der Steuerungsdurchgänge freigebbar und die anderen der Steuerungsdurchgänge verschliessbar sind.A plurality of control passages are preferably arranged at different altitudes, the drain fitting further comprising at least one closure element with which one of the control passages can be released and the other of the control passages can be closed.

Vorzugsweise erstreckt sich der Einstellbereich des Schliessgewichts in seiner Höhe mindestens bis unterhalb des obersten Steuerungsdurchgangs erstreckt.The height of the adjustment range of the closing weight preferably extends at least to below the uppermost control passage.

BESCHREIBUNG BEVORZUGTER AUSFÜHRUNGSFORMENDESCRIPTION OF PREFERRED EMBODIMENTS

In den Figuren wird eine Ablaufgarnitur 1 für einen Spülkasten gezeigt. Anhand der Figuren 1 bis 3 wird der allgemeine Aufbau der Ablaufgarnitur 1 genauer erläutert. Die Funktionsweise der Ablaufgarnitur 1 wird dann anhand der Figuren 4 bis 7 weiter unten erläutert.A drain set 1 for a cistern is shown in the figures. Based on Figures 1 to 3 the general structure of the waste set 1 is explained in more detail. The operation of the pop-up waste set 1 is then based on the Figures 4 to 7 explained below.

Die Ablaufgarnitur 1 umfasst ein Gehäuse 2 mit einer Gehäusewand 3, die aussenseitig eine Mantelfläche 4 aufweist und einen im Gehäuse 2 bewegbar gelagerten Ventilkörper 5. Die Mantelfläche 4 begrenzt die Gehäusewand 3 aussenseitig und bildet die Aussenfläche der Gehäusewand 3.The drain fitting 1 comprises a housing 2 with a housing wall 3, which has an outer surface 4 on the outside and a valve body 5 movably mounted in the housing 2. The outer surface 4 delimits the housing wall 3 on the outside and forms the outer surface of the housing wall 3.

Der Ventilkörper 5 umfasst einen Schwimmer 6 und ist entlang einer Mittelachse M von einer Ruhelage in eine Spüllage und von der Spüllage in die Ruhelage bewegbar. Weiter umfasst der Ventilkörper ein Dichtungselement 21, welches mit einem Ventilsitz 22 zusammenarbeitet. In der Ruhelage liegt das Dichtungselement 21 auf dem Ventilsitz 22 auf, derart, dass kein Wasser aus dem Spülkasten abfliesst. In der Spüllage liegt das Dichtungselement 21 beabstandet zum Ventilsitz 22 und Wasser kann aus dem Spülkasten abfliessen. Der Ventilsitz 22 ist hier Teil eines Halteelementes 28, in welchem das Gehäuse 2 gelagert ist und welches mit einer Abflussöffnung eines Spülkastens verbindbar, insbesondere einsteckbar, ist.The valve body 5 comprises a float 6 and can be moved along a central axis M from a rest position to a flushing position and from the flushing position to the rest position. The valve body further comprises a sealing element 21, which cooperates with a valve seat 22. In the rest position, the sealing element 21 rests on the valve seat 22 in such a way that no water flows out of the cistern. In the flushing position, the sealing element 21 is spaced apart from the valve seat 22 and water can flow out of the cistern. The valve seat 22 is here part of a holding element 28 in which the Housing 2 is mounted and which can be connected, in particular inserted, to a drain opening of a cistern.

Der Schwimmer 6 ist innerhalb einer durch das Gehäuse 2 begrenzten Schwimmerkammer 7 bewegbar. Dabei bewegt sich der Schwimmer 6 entlang der Mittelachse M. Weiter arbeitet der Schwimmer 6 mit der Schwimmerkammer 7 hydraulisch zusammen. Die Schwimmerkammer 7 ist im Wesentlichen als eine nach oben hin geschlossene Kammer ausgebildet und bei einer Bewegung von der Ruhelage in die Spüllage wird ein hydraulisches Gleichgewicht zwischen Schwimmer 7 und Schwimmerkammer 6 hergestellt, wobei dann der Ventilkörper 5 aufgrund dieses Gleichgewichtes in der Spüllage gehalten wird.The float 6 is movable within a float chamber 7 delimited by the housing 2. The float 6 moves along the central axis M. The float 6 also works hydraulically with the float chamber 7. The float chamber 7 is essentially designed as a chamber which is closed at the top and when moving from the rest position into the flushing position, a hydraulic balance is established between the float 7 and the float chamber 6, the valve body 5 then being held in the flushing position due to this balance.

Die Schwimmerkammer 7 umfasst mindestens einen Steuerungsdurchgang 8. In der gezeigten Ausführungsform sind mehrere Steuerungsdurchgänge 8 auf verschiedenen Höhenlagen angeordnet. Durch den mindestens einen Steuerungsdurchgang 8 kann Luft von Bereichen 9 ausserhalb der Schwimmerkammer 7 in die Schwimmerkammer 7 eintreten, wenn ein die Ablaufgarnitur 1 umgebender Spülwasserspiegel S auf die Höhe des entsprechenden Steuerungsdurchgangs 8 abgesunken ist. Durch den Lufteintritt werden die Druckverhältnisse zwischen der Schwimmerkammer und den Bereichen 9 ausserhalb der Schwimmerkammer 7 ausgeglichen und hierdurch wird das hydraulische Gleichgewicht innerhalb der Schwimmerkammer 7 gestört und der Schwimmer 6 sowie der Ventilkörper 5 wird bei Ausgleich der Druckverhältnisse von der Spüllage in die Ruhelage bewegt. Hierdurch kann eine erste Spülmenge gesteuert werden.The float chamber 7 comprises at least one control passage 8. In the embodiment shown, several control passages 8 are arranged at different altitudes. Air from areas 9 outside the float chamber 7 can enter the float chamber 7 through the at least one control passage 8 when a flushing water level S surrounding the drain fitting 1 has dropped to the level of the corresponding control passage 8. Through the air inlet, the pressure conditions between the float chamber and the areas 9 outside of the float chamber 7 are compensated and this disrupts the hydraulic balance within the float chamber 7 and the float 6 and the valve body 5 are moved from the flushing position into the rest position when the pressure conditions are equalized. In this way, a first flush volume can be controlled.

Weiterhin umfasst die Ablaufgarnitur 1 eine Steuerungseinheit 10 mit einem in seiner Höhenlage einstellbaren Schliessgewicht 12. Die Steuerungseinheit 10 dient der Steuerung einer zweiten Spülmenge. Das Schliessgewicht 12 bewirkt bei Auslösung der zweiten Spülmenge eine Schliesskraft auf den Ventilkörper 5. Das heisst, das Schliessgewicht 12 wird mit dem Ventilkörper temporär mechanisch verbunden, so dass die Gewichtskraft des Schliessgewichtes 12 auf den Ventilkörper 5 übertragbar ist. In der gezeigten Ausführungsform ist das Schliessgewicht 12 ausserhalb des Gehäuses 2 seitlich zur Mantelfläche 4 und relativ zur Mantelfläche 4 bewegbar angeordnet. Bei einer Betätigung der Steuerungseinheit 10 wird das Schliessgewicht 12 angehoben und dem Ventilkörper 5 zugeschaltet.Furthermore, the drain fitting 1 comprises a control unit 10 with a closing weight 12 that can be adjusted in height. The control unit 10 serves to control a second flushing quantity. When the second flush volume is triggered, the closing weight 12 causes a closing force on the valve body 5. This means that the closing weight 12 is temporarily mechanically connected to the valve body, so that the weight of the closing weight 12 can be transferred to the valve body 5. In the embodiment shown, the closing weight 12 is arranged to be movable outside the housing 2 laterally to the lateral surface 4 and relative to the lateral surface 4. When the control unit 10 is actuated, the closing weight 12 is raised and the valve body 5 switched on.

Weiter umfasst die Ablaufgarnitur 1 einen fluidisch oder elektrisch ansteuerbaren Aktuator 11. Mit dem Aktuator 11 lässt sich der Ventilkörper 5 von der Ruhelage in die Spüllage anheben. Es ist dabei ein direktes und/oder ein indirektes Anheben, was weiter unten noch ausgeführt wird, möglich. Der Aktuator 11 ist seitlich zur Mantelfläche 4 und bezüglich der Mittelachse M gesehen gegenüber des ausserhalb des Gehäuses 2 angeordneten Schliessgewichts 12 angeordnet. Das heisst, der Aktuator und das Schliessgewicht 12 liegen ausserhalb der Mantelfläche 4 bezüglich der Mittelachse M gesehen einander diametral gegenüber. Bei einer Bewegung des Schliessgewichtes 12 entlang der Mittelachse M kommt es aufgrund der gegenüberliegenden Anordnung des Aktuators 11 zu keiner Kollision zwischen Aktuator 11 und Schliessgewicht 12. Das Schliessgewicht 12 kann sich also auf eine Höhenlage bewegen, auf welcher der Aktuator 11 angeordnet ist. Die Mantelfläche 4 weist in der gezeigten Ausführungsform eine Einbuchtung 30 auf, welche den Querschnitt des Gehäuses 2 verkleinert, so dass die Kompaktheit erhöht werden kann.The drain fitting 1 further comprises a fluidically or electrically controllable actuator 11. With the actuator 11, the valve body 5 can be raised from the rest position to the flushing position. Direct and / or indirect lifting, which will be explained further below, is possible. The actuator 11 is arranged laterally to the lateral surface 4 and, viewed with respect to the central axis M, opposite the closing weight 12 arranged outside the housing 2. This means that the actuator and the closing weight 12 lie diametrically opposite one another outside the lateral surface 4 with respect to the central axis M. When the closing weight 12 moves along the central axis M, because of the opposite arrangement of the actuator 11, there is no collision between the actuator 11 and the closing weight 12. The closing weight 12 can therefore move to a height position on which the actuator 11 is arranged. In the embodiment shown, the lateral surface 4 has an indentation 30 which reduces the cross section of the housing 2, so that the compactness can be increased.

Die diametral gegenüberliegende Anordnung des Aktuators 11 bezüglich des Schliessgewichtes 12 hat zudem den besonderen Vorteil, dass die Ablaufgarnitur vergleichsweise kompakt ausgebildet werden kann. Dies ist gerade beim Einbau der Ablaufgarnitur 1 in einen Spülkasten von grossem Vorteil.The diametrically opposite arrangement of the actuator 11 with respect to the closing weight 12 also has the particular advantage that the drain fitting can be made comparatively compact. This is of great advantage especially when installing the waste set 1 in a cistern.

Vorzugsweise liegen der Aktuator 11 und das Schliessgewicht 12 zwischen zwei parallel zueinander liegenden Begrenzungsebenen Z. Die Begrenzungsebenen Z verlaufen im Wesentlichen parallel zur Mittelachse M und stehen jeweils vorzugsweise in gleichem Abstand beanstandet zur Mittelachse M. Der Abstand ist dabei vorzugsweise so gewählt, dass die Begrenzungsebenen Z sich durch die maximale Ausdehnung der die Schwimmerkammer 7 begrenzenden Mantelfläche 4 verlaufen. Die maximale Ausdehnung und somit der Lagepunkt der Bezugsebene ist in der Figur 3 mit einem X eingezeichnet.The actuator 11 and the closing weight 12 are preferably located between two boundary planes Z lying parallel to one another. The boundary planes Z run essentially parallel to the central axis M and are each preferably at the same distance from the central axis M. The distance is preferably selected such that the boundary planes Z extend through the maximum extent of the lateral surface 4 delimiting the float chamber 7. The maximum extent and thus the position of the reference plane is in the Figure 3 marked with an X.

Der Aktuator 11 ist in der gezeigten Ausführungsform so ausgebildet, dass dieser ausschliesslich zum Anheben des Ventilkörpers 5 dient. Der Ventilkörper 5 wird demnach in der Spüllage nicht durch den Aktuator 11 gehalten, sondern durch das Zusammenspiel zwischen Schwimmer 6 und Schwimmerkammer 7. Das heisst, der Ventilkörper 5 wird aufgrund des hydraulischen Gleichgewichtes in der Schwimmerkammer 7 in der Spüllage gehalten. Für die Bewegung von der Spüllage in die Ruhelage sind die oben beschriebenen Elemente, nämlich der Strömungsdurchgang 8 und das Schliessgewicht 12 verantwortlich.In the embodiment shown, the actuator 11 is designed such that it is used exclusively for lifting the valve body 5. The valve body 5 is therefore not held in the flushing position by the actuator 11, but rather by the interaction between float 6 and float chamber 7. This means that the valve body 5 is kept in the flushing position due to the hydraulic balance in the float chamber 7. The elements described above, namely the flow passage 8 and the closing weight 12, are responsible for the movement from the flushing position into the rest position.

In der gezeigten Ausführungsform wirkt der Aktuator 11 für die erste Spülmenge direkt auf den Ventilkörper 5. Hierfür weist der Aktuator 11 einen Aktuatorhebel 15 auf, welcher mit einem Rand 23 am Ventilkörper 5 zusammenarbeitet und diesen Rand 23 entgegen der Schwerkraft gesehen von unten angreift und so den Ventilkörper 5 von der Ruhelage in die Spüllage bewegt. In der Figur 6 wird die Ausgangslage gezeigt, in welcher der Aktuatorhebel 15 beabstandet zum Rand 23 liegt. Nach Betätigung fährt der Aktuatorhebel 15 nach oben und trifft dabei auf den Rand 23 und hebt über den Rand 23 den Ventilkörper 5 an. Dies wird in der Figur 7 gezeigt.In the embodiment shown, the actuator 11 acts directly on the valve body 5 for the first flushing quantity. For this purpose, the actuator 11 has an actuator lever 15, which cooperates with an edge 23 on the valve body 5 and engages this edge 23 from below, against gravity, and so on the valve body 5 moved from the rest position to the flushing position. In the Figure 6 the starting position is shown, in which the actuator lever 15 is spaced from the edge 23. After actuation, the actuator lever 15 moves upwards and hits the edge 23 and lifts the valve body 5 via the edge 23. This is in the Figure 7 shown.

Weiter arbeitet der Aktuator 11 in der gezeigten Ausführungsform mit der Steuerungseinheit 10 für die zweite Spülmenge zusammen. Hierfür weist der Aktuator 11 einen zweiten Aktuatorhebel 16 auf, welcher in der gezeigten Ausführungsform auf einen von der Steuerungseinheit 10, hier von der Lagerstange 13, abstehenden Mitnehmer 24 wirkt. In den Figuren 4 und 5 wird das Zusammenspiel zwischen dem zweiten Aktuatorhebel 16, dem Mitnehmer 24 und dem Rand 23 gezeigt. Der Mitnehmer 24 ragt in der gezeigten Ausführungsform seitlich zum Ventilkörper 5 am Ventilkörper vorbei und kommt in den Wirkbereich des zweiten Aktuatorhebels 16 zu liegen. Der Mitnehmer 24 liegt dabei unterhalb des Randes 23. Die Ausgangslage wird in der Figur 4 gezeigt, wobei hier der zweite Aktuatorhebel 16 in Kontakt mit dem Mitnehmer 24 steht. Bei einem Anheben des Mitnehmers 24 durch den zweiten Aktuatorhebel 16 schlägt der Mitnehmer 24 am Rand 23 des Ventilkörpers 5 an und hebt somit den Ventilkörper 5 von der Ruhelage in die Spüllage. Dies ist in der Figur 5 dargetsellt. Der Aktuator 11 greift somit mit dem zweiten Aktuatorhebel 16 indirekt am Ventilkörper über die Steuerungseinheit 10 an.In the embodiment shown, the actuator 11 also works together with the control unit 10 for the second flushing quantity. For this purpose, the actuator 11 has a second actuator lever 16, which in the embodiment shown acts on a driver 24 protruding from the control unit 10, here from the bearing rod 13. In the Figures 4 and 5 the interaction between the second actuator lever 16, the driver 24 and the edge 23 is shown. In the embodiment shown, the driver 24 projects laterally to the valve body 5 past the valve body and comes to rest in the effective range of the second actuator lever 16. The driver 24 is below the edge 23. The starting position is in the Figure 4 shown, here the second actuator lever 16 is in contact with the driver 24. When the driver 24 is raised by the second actuator lever 16, the driver 24 strikes the edge 23 of the valve body 5 and thus lifts the valve body 5 from the rest position to the flushing position. This is in the Figure 5 presented. The actuator 11 thus acts indirectly with the second actuator lever 16 on the valve body via the control unit 10.

In der gezeigten Ausführungsform umfasst die Steuerungseinheit 10 weiterhin eine Lagerstange 13, welche ausserhalb des Gehäuses 2 angeordnet ist. Die Lagerstange 13 dient im Wesentlichen der Lagerung des Schliessgewichtes 12, welches hier an der Lagerstange 13 relativ zur Lagerstange 13 einstellbar ausgebildet ist. Das heisst, das Schliessgewicht 12 kann über einen Einstellbereich E in seiner Höhenlage eingestellt werden, wodurch die aus dem Spülkasten zu entnehmende Spülmenge eingestellt werden kann. Je höher das Schliessgewicht 12 liegt, desto geringer ist die aus dem Spülkasten zu entnehmende Spülwassermenge. Der Einstellbereich E erstreckt sich vorzugsweise bezüglich seiner Höhenlage bis in einen Bereich gegenüber des Aktuators 11. Das heisst, dass das Schliessgewicht 12 auf eine Höhenlage bewegbar ist, welche gegenüber des Aktuators 11 liegt. Hier zeigt sich ein weiterer Vorteil der diametral gegenüberliegenden Anordnung zwischen Schliessgewicht 12 und Aktuator 11, weil der Einstellbereich der Höhenlage des Schliessgewichtes 12 bis auf die Höhe des Aktuators 11 reichen kann und sich somit der Bereich der Menge des Spülwassers bei der zweiten Spülung vergrössert einstellen lässt.In the embodiment shown, the control unit 10 further comprises a bearing rod 13, which is arranged outside the housing 2. The bearing rod 13 is essentially used to support the closing weight 12, which here on the Bearing rod 13 is adjustable relative to the bearing rod 13. This means that the closing weight 12 can be adjusted in its height by means of an adjustment range E, whereby the flush volume to be removed from the cistern can be adjusted. The higher the closing weight 12, the lower the amount of flushing water that can be removed from the cistern. The setting range E preferably extends with respect to its height position into a region opposite the actuator 11. This means that the closing weight 12 can be moved to a height position which lies opposite the actuator 11. This shows a further advantage of the diametrically opposite arrangement between the closing weight 12 and the actuator 11, because the setting range of the height of the closing weight 12 can reach up to the height of the actuator 11 and the range of the amount of rinsing water during the second rinsing can thus be increased .

Das Schliessgewicht 12 ist über ein Schaltorgan 14 mit dem Ventilkörper 5 mechanisch und temporär verbindbar. Das Schaltorgan 14 stellt also eine temporäre mechanische Verbindung zwischen dem Schliessgewicht 12 und dem Ventilkörper 5 bereit. Dabei geht das Schaltorgan 14 beim Anheben der Steuerungseinheit 5 selbsttätig mit dem Ventilkörper 2 eine Rastverbindung ein. Das Schaltorgan 14 ist bevorzugt gelenkig an der Lagerstange 13 gelagert und wird bei der Bewegung der Steuerungseinheit 10 inklusive der Lagerstange 13 von der Ruhelage in die Spüllage mit dem Ventilkörper 5 verbunden. Über diese Verbindung wirkt dann die Kraft auf den Ventilkörper 5.The closing weight 12 can be mechanically and temporarily connected to the valve body 5 via a switching element 14. The switching element 14 thus provides a temporary mechanical connection between the closing weight 12 and the valve body 5. The switching element 14 automatically engages with the valve body 2 when the control unit 5 is raised. The switching element 14 is preferably articulated on the bearing rod 13 and is connected to the valve body 5 when the control unit 10 including the bearing rod 13 moves from the rest position into the flushing position. The force then acts on the valve body 5 via this connection.

In der gezeigten Ausführungsform umfasst sowohl der Ventilkörper 5 als auch die Steuerungseinheit 10, hier im Bereich des oberen Endes der Lagerstange 13 je ein Zugbügel 25, 26. Über diese Zugbügel ist es möglich, die Ablaufgarnitur ohne das Vorhandensein des Aktuators 11 zu betätigen.In the embodiment shown, both the valve body 5 and the control unit 10, here in the region of the upper end of the bearing rod 13, each have a pull bracket 25, 26. Via these pull brackets, it is possible to actuate the drain fitting without the presence of the actuator 11.

Der Aktuator 11 ist in der gezeigten Ausführungsform über eine Rastverbindung mit dem Gehäuse 2 verbindbar. Hierfür weist die Mantelfläche 4 im oberen Bereich eine Aufnahmestruktur 19 auf und der Aktuator 11 weist mindestens ein Rastelement 20 auf, welches in die Aufnahmestruktur 19 eingreift. Das Rastelement 20 greift dabei derart in die Aufnahmestruktur 19 ein, dass der Aktuator mit dem Gehäuse 2 lösbar verbindbar ist. Die Aufnahmestruktur 19 liegt bezüglich der Mittelachse M diametral gegenüber vom Schliessgewicht 12.In the embodiment shown, the actuator 11 can be connected to the housing 2 via a snap-in connection. For this purpose, the outer surface 4 has a receiving structure 19 in the upper region and the actuator 11 has at least one latching element 20 which engages in the receiving structure 19. The latching element 20 engages in the receiving structure 19 in such a way that the actuator can be detachably connected to the housing 2. The receiving structure 19 is diametrically opposite to the central axis M. Closing weight 12.

Wie von den Figuren 4 bis 7 gezeigt wird, ist der Aktuator 11 ein pneumatischer Aktuator mit zwei übereinander angeordneten Kolben 17, 18 ist. Die Kolben 17, 18 liegen auf einer gemeinsamen Kolbenachse K und werden über Luftleitungen 29 mit Luft versorgt, so dass eine Bewegung der Kolben 17, 18 ermöglicht wird.As from the Figures 4 to 7 is shown, the actuator 11 is a pneumatic actuator with two pistons 17, 18 arranged one above the other. The pistons 17, 18 lie on a common piston axis K and are supplied with air via air lines 29, so that the pistons 17, 18 can move.

In den Figuren 4 und 5 wird die Auslösung der Teilmengenspülung dargestellt. In der Figur 4 liegt der Ventilkörper 5 in seiner Ruhelage, wobei das Dichtungselement 21 auf den Ventilsitz 22 aufliegt. In der Figur 5 liegt der Ventilkörper 5 in seiner Spüllage, wobei das Dichtungselement 21 beabstandet zum Ventilsitz 22 liegt. Bei Betätigung des Aktuators 11 dehnt sich der Kolben 18 entsprechend aus und über den zweiten Aktuatorhebel 16 wird die Steuerungseinheit 10 angehoben. Aufgrund des Mitnehmers 24 wird zudem auch der Ventilkörper 5 angehoben. Sodann kann Wasser aus dem Spülkasten abfliessen und der Wasserstand senkt sich ab. Sobald der Wasserstand das Schliessgewicht 12 erreicht hat, fällt dessen Auftrieb weg und dessen Schwerkraft wird wirksam und drückt den Ventilkörper 5 nach unten.In the Figures 4 and 5 the triggering of partial flushing is shown. In the Figure 4 the valve body 5 is in its rest position, the sealing element 21 resting on the valve seat 22. In the Figure 5 the valve body 5 lies in its flushing position, the sealing element 21 being spaced apart from the valve seat 22. When the actuator 11 is actuated, the piston 18 expands accordingly and the control unit 10 is raised via the second actuator lever 16. Due to the driver 24, the valve body 5 is also raised. Then water can flow out of the cistern and the water level drops. As soon as the water level has reached the closing weight 12, its buoyancy ceases and its gravity takes effect and presses the valve body 5 downward.

Bezüglich der Betätigung des Kolbens 18 ist anzumerken, dass dies eine kurzzeitige Betätigung ist und im Wesentlichen dazu dient, den Ventilkörper 5 in seine Spüllage anzuheben. Sobald die Spüllage erreicht ist geht der Aktuator 11 mit dem Kolben 18 in seine Ausgangslage zurück.With regard to the actuation of the piston 18, it should be noted that this is a brief actuation and essentially serves to lift the valve body 5 into its flushing position. As soon as the flushing position is reached, the actuator 11 returns to its starting position with the piston 18.

In den Figuren 6 und 7 wird nun die Auslösung einer Vollmengenspülung gezeigt. Dabei wird der erste Kolben 17 betätigt und der erste Aktuatorhebel 15, welcher hier direkt auf den Rand 23 des Ventilsitzes 22 wirkt, wird nach oben bewegt. Hierbei verbleibt dann der Ventilkörper 5 in seiner Spüllage. Sobald der Wasserspiegel auf die Höhe des Steuerungsdurchgangs abgesunken ist, wird das hydraulische Gleichgewicht im Inneren der Schwimmerkammer 7 aufgelöst und der Ventilkörper 5 bewegt sich von der Spüllage in die Ruhelage zurück.In the Figures 6 and 7 the triggering of a full flush is now shown. The first piston 17 is actuated and the first actuator lever 15, which here acts directly on the edge 23 of the valve seat 22, is moved upward. The valve body 5 then remains in its flushing position. As soon as the water level has dropped to the level of the control passage, the hydraulic balance in the interior of the float chamber 7 is released and the valve body 5 moves back from the flushing position to the rest position.

In der gezeigten Ausführungsform sind mehrere Steuerungsdurchgänge 8 auf verschiedenen Höhenlagen angeordnet. Die Ablaufgarnitur 1 umfasst weiterhin ein Verschlusselement 27, mit welchem die Steuerungsdurchgänge wahlweise abgedeckt werden können.
