Abstract

A flushing device has two water outlets, wherein one outlet is connected to an arch of a trap of the toilet bowl. This outlet is connected to means with which a portion of the flushing water present in a flushing tank can be pressurized and released to this outlet. The water is briefly set into motion with the pressurized flushing water, and more effective emptying of the trap is achieved. The flushing device according to the present invention represents a lower load for the water pipes and operates with less noise than flushing valve-type devices.

Description

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

Eine Vorrichtung dieser Art ist durch die EP-A-0 352 712 bekannt geworden. Bei dieser Spülvorrichtung sind zwei Wasserzuführungen zu einer Klosettschüssel vorgesehen. Die eine Wasserzuführung führt zum Schüsselrand und die andere Zuführung zu einem im unteren Bereich der Schüssel angeordneten Geruchsverschluss. Bei einer Spülung wird mit einem Spülwasserstrom die Schüssel gereinigt und mit einem anderen Spülwasserstrom das im Geruchsverschluss vorliegende Wasser in Bewegung gesetzt. Die für eine wirksame Spülung minimal erforderliche Wassermenge ist bei einer solchen Spülvorrichtung wesentlich kleiner als bei einer Spülvorrichtung mit lediglich einem Spülstrom zum Reinigen der Klosettschüssel. Bei der in Fig. 1 gezeigten Ausführung ist die Spülvorrichtung als sogenannter Druckspüler ausgebildet. Zur Steuerung der beiden Spülwasserströme ist hier eine vergleichsweise aufwendige Steuervorrichtung erforderlich. Nachteilig ist bei dieser Ausführung zudem, dass trotz der vergleichsweise kleinen Spülwassermenge bei einer Spülung störende Geräusche entstehen. Druckspüler sind zudem in einigen Ländern nicht zugelassen. In Fig. 7 ist eine Ausführung gezeigt, bei der das für eine Spülung verwendete Wasser in einem Spülwasserbehälter gelagert ist. An eine Abgangsleitung des Spülwasserbehälters ist eine Zweigleitung angeschlossen, die zum Geruchsverschluss der Klosettschüssel führt. Auch bei dieser Ausführung sind eine aufwendige Steuereinrichtung und in den Leitungen Ventile und Druckanzeigevorrichtungen erforderlich, mit denen die beiden Spülwasserströme gesteuert werden.A device of this kind is known from EP-A-0 352 712 known. This flushing device has two water inlets provided for a toilet bowl. The one water supply leads to the bowl rim and the other Feed to one located in the lower area of the bowl Odor trap. In the case of a rinse with a Rinsing water flow cleaned the bowl and with another Flushing water flow in the odor trap Water set in motion. The one for an effective rinse the minimum amount of water required is one Rinsing device much smaller than in a rinsing device with just one flushing stream to clean the Toilet bowl. In the embodiment shown in Fig. 1 is the flushing device is designed as a so-called flush valve. To control the two rinse water flows is here a comparatively complex control device is required. Another disadvantage of this version is that despite the comparatively small amount of rinse water at one Flushing disturbing noises occur. Flushers are also not approved in some countries. 7 is one Execution shown, which used for a rinse Water is stored in a rinse water tank. To one The outlet line of the rinsing water tank is a branch line connected to the odor trap of the toilet bowl leads. This version is also a complex one Control device and in the lines valves and Pressure gauges required with which the two Flushing water flows can be controlled.

Aehnliche Spülvorrichtungen zeigen die EP-A-0 369 377 und die EP-A-0 415 432. Auch bei diesen Ausführungen sind aufwendige Steuer- und Kontrolleinheiten erforderlich.Similar flushing devices are shown in EP-A-0 369 377 and EP-A-0 415 432. These designs are also complex Control and monitoring units required.

Der Erfindung liegt die Aufgabe zugrunde, eine Spülvorrichtung der genannten Art zu schaffen, die im Vergleich zu Druckspülvorrichtungen das Leitungsnetz wesentlich weniger belastet, geräuschärmer arbeitet und die mit einer minimalen Spülwassermenge die erforderliche Spülwirkung erreicht. The invention has for its object a flushing device of the type mentioned, which compared to Pressure flushing devices make the pipe network much less burdened, works less noisy and with a minimal Rinse water quantity reaches the required rinsing effect.

Die Aufgabe ist bei einer gattungsgemässen Spülvorrichtung gemäss Kennzeichen des Patentanspruchs 1 gelöst.The task is with a generic flushing device solved according to the characteristics of claim 1.

Bei der erfindungsgemässen Spülvorrichtung wird eine Teilmenge des im Spülwasserbehälter befindlichen Spülwassers während des Spülvorganges unter Druck gesetzt. Dieses unter Druck befindliche Wasser wird an den Auslauf abgegeben, der zu dem im unteren Bereich der Klosettschüssel angeordneten Geruchsverschluss führt. Mit der erfindungsgemässen Spülvorrichtung ist es deshalb möglich, das Wasser im Geruchsverschluss so zu beschleunigen, dass dieser Geruchsverschluss besser ausgespült wird. Das Wasser des Geruchsverschlusses wird kurzzeitig in Bewegung gesetzt und eine effektivere Entleerung des Geruchsverschlusses erreicht. Mit dem schwerkraftbelasteten Spülstrom muss dann lediglich die Klosettschüssel gereinigt und der teilweise geleerte Geruchsverschluss nachgefüllt werden. Bei der erfindungsgemässen Spülvorrichtung wird bei einer Spülung somit eine drucklose und eine unter Druck gesetzte Spiilwassermenge abgegeben. Verglichen mit einem üblichen Spülkasten wird somit bei gleicher Spülwirkung eine geringere Spülwassermenge benötigt. Im Vergleich zu Druckspülvorrichtungen belastet die erfindungsgemässe Spülvorrichtung das Leitungsnetz wesentlich geringer und entspricht in dieser Hinsicht einem üblichen Spülkasten.In the flushing device according to the invention, a subset of the rinsing water in the rinsing water tank pressurized during the rinsing process. This under Water under pressure is released to the spout to the one arranged in the lower area of the toilet bowl Odor trap leads. With the flushing device according to the invention it is therefore possible to keep the water in the odor trap to speed up that odor trap is better rinsed out. The water of the odor trap is set in motion briefly and achieved a more effective emptying of the odor trap. Then with the gravity-loaded flushing current must only the toilet bowl cleaned and partially emptied odor trap. In the case of the Flushing device is thus in a rinse an unpressurized and a pressurized amount of rinse water submitted. Compared to a normal cistern is therefore less with the same rinsing effect Amount of rinse water required. Compared to pressure flushing devices stresses the flushing device according to the invention Line network much smaller and corresponds to this Regarding a normal cistern.

Nach einer Weiterbildung der Erfindung weisen die Mittel, mit denen eine Spülwassermenge unter Druck setzbar ist, eine Zylinderkolbeneinheit mit einem Kolben auf, der bei einer Spülung mit dem Wasser der Wasserversorgungsleitung beaufschlagbar ist. Der Kolben wird durch den Druck des Wassers aus der Versorgungsleitung verschoben und eine in der Einheit vorliegende bestimmte Spülwassermenge unter Druck gesetzt. Eine solche Zylinderkolbeneinheit kann in einem Spülkasten untergebracht sein. Ein solcher Spülkasten kann dann wie üblich mit einer Taste betätigbar sein.According to a development of the invention, the means with which a flushing water quantity can be put under pressure, a cylinder piston unit with a piston, which at a flushing with the water of the water supply line is acted upon. The piston is driven by the pressure of the Water moved from the supply line and one in amount of rinse water present in the unit Pressure put. Such a cylinder piston unit can in a cistern. Such a cistern can then be operated with a button as usual.

Eine besonders wirksame Spülung wird dann erreicht, wenn mittels einer Steuervorrichtung das in der Zylinderkolbeneinheit befindliche Wasser verzögert unter Druck abgegeben wird. Dadurch kann erreicht werden, dass der schwerkraftbelastete Spülstrom und der unter Druck beaufschlagte Spülstrom im wesentlichen gleichzeitig im Siphon bzw. Geruchsverschluss wirksam werden. Diese Steuervorrichtung kann konstruktiv besonders einfach durch einen Schwimmer realisiert werden, der ein servogesteuertes Einlaufventil betätigt.A particularly effective flushing is achieved when by means of a control device in the cylinder-piston unit Existing water is released under pressure becomes. This can be achieved that the gravity Flushing stream and the flushing stream under pressure essentially at the same time in the siphon or odor trap be effective. This control device can constructively realized particularly simply by a float be operated by a servo-controlled inlet valve.

Die Erfindung betrifft ebenfalls eine Klosettanlage mit einer Spülvorrichtung gemäss Anspruch 16.The invention also relates to a toilet system with a Flushing device according to claim 16.

Bei einer solchen Klosettanlage ist die Spülwirkung dann besonders wirksam, wenn gemäss einer Weiterbildung der Erfindung die Düse bezüglich der Horizontalen derart geneigt angeordnet ist, dass das durch die Düse abgegebene Spülwasser eine stromabwärts gerichtete Bewegung auf das im Bogen des Geruchsverschlusses befindliche Wasser ausübt. In such a lavatory system, the rinsing effect is then particularly effective if according to a further development of the invention the nozzle is inclined with respect to the horizontal is arranged that the flushing water discharged through the nozzle a downstream movement to that in the arch water in the trap.

Weitere vorteilhafte Merkmale ergeben sich aus den abhängigen Patentansprüchen, der nachfolgenden Beschreibung sowie den Zeichnungen.Further advantageous features result from the dependent ones Claims, the description below and the drawings.

Die Fig. 1 zeigt eine Spülvorrichtung 1, die über einen Rohrbogen 12 mit einer Klosettschüssel 45 verbunden ist. In einem Kasten 8 der Spülvorrichtung 1 ist ein Ablaufventil 13 untergebracht, das zur Freigabe einer Oeffnung 55 im Boden des Kastens 8 mit einer Betätigungsvorrichtung 17 betätigbar ist. Die Betätigungsvorrichtung 17 kann eine Taste oder ein Druckknopf oder eine andere Auslösevorrichtung sein. Im Kasten 8 befindet sich zudem ein Einlaufventil 4, das an eine Wasserversorgungsleitung 2 angeschlossen ist. Bei geöffnetem Einlaufventil 4 wird der Kasten 8 bis zu einem vorbestimmten Niveau mit Spülwasser 50 gefüllt. Beim Oeffnen des Ablaufventils 13 strömt ein Teil des Spülwassers 50 durch den Rohrbogen 12 in einen Kanal 51 eines Randes 47 und strömt in Richtung der Pfeile 53 an der Innenseite eines Beckens 56 nach unten in einen U-förmigen Bogen 46, der gegenüber einem Abgang 52 einen Geruchsverschluss bildet. Ein weiterer wesentlich geringerer Teil des Spülwassers 50 wird mit weiter unten näher beschriebenen Mitteln im Kasten 8 unter Druck gesetzt und gelangt über eine Leitung 9 zu einer Düse 11, die einen Durchgang 57 in das Innere des Bogens 46 aufweist. Diese Düse 11 ist so gerichtet, dass, wie in Fig. 1 gezeigt, durch die Düse 11 einströmendes Wasser in Richtung des Pfeiles 58 in das im Bogen 46 vorliegende Wasser 70 einströmt. Die Richtung des Pfeiles 58 ist gleichzeitig die Strömungsrichtung des Wassers 70 beim Spülvorgang und somit beim Entleeren des Geruchsverschlusses. Ein geeigneter Neigungswinkel α ist der Fig. 1 zu entnehmen. Dieser Winkel α beträgt beispielsweise etwa 10° und ist vorzugsweise kleiner als 45°.1 shows a flushing device 1, which has a Pipe elbow 12 is connected to a toilet bowl 45. In a box 8 of the flushing device 1 is a drain valve 13 housed that to release an opening 55 in the bottom of the box 8 can be actuated by an actuating device 17 is. The actuator 17 can be a button or a push button or other trigger device be. In box 8 there is also an inlet valve 4, which is connected to a water supply line 2. When the inlet valve 4 is open, the box 8 is up to one predetermined level filled with rinse water 50. At the Part of the rinse water flows when the drain valve 13 is opened 50 through the pipe bend 12 into a channel 51 of an edge 47 and flows in the direction of arrows 53 on the inside a basin 56 down into a U-shaped arch 46, an odor trap opposite an outlet 52 forms. Another much smaller part of the rinse water 50 is by means described in more detail below pressurized in box 8 and passes through a Line 9 to a nozzle 11 which has a passage 57 in it Has interior of the arch 46. This nozzle 11 is directed that, as shown in Fig. 1, flowing through the nozzle 11 Water in the direction of arrow 58 in the arch 46 present water 70 flows. The direction of the Arrow 58 is also the direction of flow of the water 70 during the rinsing process and thus when the odor trap is emptied. A suitable angle of inclination α is 1. This angle α is, for example about 10 ° and is preferably less than 45 °.

Der durch die Düse 11 einströmende Spülstrom weist beispielsweise einen kleinen Ueberdruck auf, während das durch den Kanal 51 in die Schüssel 56 einströmende Spülwasser lediglich schwerkraftbelastet ist. Die bei einer Spülung durch die Düse 11 einströmende Spülwassermenge ist vorzugsweise wesentlich kleiner als das durch den Kanal 51 abgegebene Spülwasser. Das unter Ueberdruck in Richtung des Pfeiles 58 in das Wasser einströmende Spülwasser bewegt das Wasser 70 in Richtung des Pfeiles 58 und bewirkt, dass der Bogen 46 besser ausgespült wird. Im Bogen 46 befindliche Exkremente werden hierbei mitgerissen und zum Abgang 52 befördert. Im wesentlichen gleichzeitig mit der Reinigung des Bogens 46 gelangt durch den Kanal 51 schwerkraftbelastetes Spülwasser in das Becken 56 und reinigt dieses. Das nach unten in den Bogen 46 strömende schwerkraftbelastete Spülwasser verstärkt die Bewegung des Wassers 70 in Richtung des Pfeiles 58 und füllt den Bogen 46 mit Wasser wieder auf. Beide Spülströme wirken somit zusammen und beschleunigen das Wasser 70 um damit den Bogen 46 von Exkrementen zu reinigen.The flushing stream flowing through the nozzle 11 has, for example a little overpressure while the through rinsing water flowing into the channel 56 into the bowl 56 only is gravitational. The one with a rinse Amount of rinse water flowing through the nozzle 11 is preferred much smaller than that emitted through channel 51 Rinse water. The under pressure in the direction of the arrow 58 rinsing water flowing into the water moves that Water 70 in the direction of arrow 58 and causes the Bow 46 is better rinsed out. Located in sheet 46 Excrement is carried away and transported to the outlet 52. Essentially simultaneously with the cleaning of the Bow 46 passes through the channel 51 gravity Rinse water in the basin 56 and cleans it. That after gravity-loaded rinsing water flowing into the bow 46 below enhances the movement of water 70 towards of arrow 58 and refills the sheet 46 with water on. Both flushing currents thus work together and accelerate the water 70 so that the bow 46 of excrement clean.

Die Fig. 2 und 3 zeigen eine bevorzugte Ausführung der Spülvorrichtung 1. Der Kasten 8 kann ein an sich üblicher Kasten mit einem im Boden angeordneten Abgangsstutzen 59 und einem hier nicht gezeigten Deckel sein. Am Stutzen 59 ist der Rohrbogen 12 an den Kasten 8 angeschlossen. Das Ablaufventil 13 kann ein bekanntes Schwimmerventil sein, bei dem in einem Schwimmergehäuse 60 ein Ventilrohr 16 geführt ist. An einer Oese 19 kann das Ventilrohr 16 mit einer um ein Lager 18 verschwenkbaren Taste 17 angehoben werden. Ein Ventilteller 15 gibt hierbei die Oeffnung 14 frei, worauf im Kasten 8 befindliches Spülwasser 50 durch den Rohrbogen 12 in den Kanal 51 strömt. Nach dem Spülvorgang schliesst das Ablaufventil 13 in bekannter Weise selbsttätig. 2 and 3 show a preferred embodiment of the Flushing device 1. The box 8 can be a conventional one Box with an outlet connection 59 arranged in the floor and a cover, not shown here. At the socket 59 the pipe bend 12 is connected to the box 8.

Eine Durchgangsöffnung 63 in der Membran 27 verbindet eine Kammer 29a des Stutzens 62 mit einer Kammer 26 eines Gestells 23. In der Kammer 26 befindet sich Wasser, das durch die Oeffnung 63 mit dem Wasser der Versorgungsleitung 2 in Verbindung ist und den gleichen Druck aufweist. Da nun die Membran 27 gegenüber der Kammer 26 eine grössere Fläche aufweist als gegenüber der Kammer 29a wird diese gegen oben an den Ventilsitz der Oeffnung 28 angepresst. Die Kammer 26 weist einen Durchgang 25 auf, der in der gezeigten Anordnung durch eine am Gestell 23 verschiebbar gelagerte Ventilstange 24 verschlossen ist. Am unteren Ende der Ventilstange 24 ist ein Schwimmer 21 angebracht, der sich in einem Schwimmergehäuse 20 befindet. Bei gefülltem Spülkasten befindet sich der Schwimmer 21 weitgehend unterhalb des durch den Buchstaben A markierten Wasserstandes. Im Boden des Schwimmergehäuses 20 ist ein Ventil 22 angeordnet, das bei gefülltem Spülkasten offen ist und somit den Innenraum des Schwimmergehäuses 20 mit seiner Aussenseite verbindet. Das Gehäuse 20 ist mit Wasser gefüllt und verleiht dem Schwimmer 21 einen Auftrieb, der die Stange 24 an einem Ventilsitz der Durchgangsöffnung 25 anpresst.The inlet valve 4 is a servo-controlled diaphragm valve. In the state shown in FIG. 2, this closes with a membrane 27 an opening 28 in a passage 29. A passage opening 63 in the membrane 27 connects a chamber 29a of the Nozzle 62 with a chamber 26 of a frame 23. In the Chamber 26 contains water flowing through opening 63 is connected to the water of the supply line 2 and has the same pressure. Since the membrane 27 now opposite the chamber 26 has a larger area than opposite the chamber 29a becomes the valve seat at the top the opening 28 pressed. The chamber 26 has one Passage 25 on, in the arrangement shown by a on the frame 23 slidably mounted valve rod 24 is closed is. At the lower end of the valve rod 24 is a Float 21 attached, which is in a float housing 20 is located. When the cistern is full, the Float 21 largely below that indicated by the letter A marked water level. In the bottom of the float housing 20 is a valve 22 which is arranged when the cistern is full is open and thus the interior of the float housing 20 connects with its outside. The housing 20 is filled with water and gives float 21 a buoyancy, the rod 24 on a valve seat of the through opening 25 pressed.

Wird nun bei einer Spülung mit der Taste 17 das Ventilrohr 16 angehoben, so sinkt der Wasserstand im Spülkasten 8 und gleichzeitig auch der Stand des Wassers im Schwimmergefäss 20. Der Auftrieb des Schwimmers 21 wird somit zunehmend kleiner, bis schliesslich dieser durch das Eigengewicht nach unten fällt und damit die Durchgangsöffnung 25 freigegeben wird. Durch den Durchgang 25 kann aus der Kammer 26 Wasser nach aussen entweichen, wodurch der Druck in der Kammer 26 sofort erniedrigt wird. Durch den nun höheren Wasserdruck in der Kammer 29a wird die Membran 27 nach unten bewegt und von der Oeffnung 28 abgehoben. Der Durchgang von der Kammer 29a zur Kammer 29b ist damit offen. Von der Versorgungsleitung 2 kann nun durch den Durchgang 29 Wasser in eine Kammer 5 gelangen, die gegenüber einem Innenraum 64 des Gehäuseteils 33 mit einem Kolben 30 und einer umlaufenden Lippendichtung 31 abgedichtet ist. Ein vor der Membran 27 angeordneter Mengenregler 3 begrenzt die pro Zeiteinheit in die Kammer 5 einfliessende Wassermenge. Der Mengenregler 3 ist vorzugsweise so eingestellt, dass das in die Kammer 5 einströmende Wasser einen maximalen Fliessdruck aufweist.If the valve tube is now flushed with button 17 16 raised, the water level in the cistern 8 and at the same time the level of the water in the float tank 20. The buoyancy of the float 21 is thus increasing smaller, until finally this due to its own weight falls down and thus the passage opening 25 is released becomes. Through the passage 25 from the chamber 26th Water escapes to the outside, causing the pressure in the Chamber 26 is immediately lowered. By the now higher Water pressure in chamber 29a causes membrane 27 to go down moved and lifted from the opening 28. The passage from chamber 29a to chamber 29b is thus open. Of the Supply line 2 can now through the passage 29 water get into a chamber 5 which is opposite an interior 64 of the housing part 33 with a piston 30 and a rotating one Lip seal 31 is sealed. One in front of the membrane 27 arranged volume controller 3 limits per unit time amount of water flowing into the chamber 5. The flow regulator 3 is preferably set so that it enters the chamber 5 inflowing water has a maximum flow pressure.

Der Kolben 30 ist über einen Steg 32 mit einem weiter unten angeordneten Kolben 37 fest verbunden. Dieser Kolben 37 weist ein Rückschlagventil 36 auf, das in der gezeigten Stellung geöffnet ist und den Innenraum 64 mit einem Innenraum 65 des Gehäuseteils 40 verbindet. Bei geschlossenem Ventil 36 dichtet der Kolben 37 mit einer umlaufenden Lippendichtung 38 den Innenraum 65 gegen den Raum 64 ab. Die beiden Kolben 30 und 37 bilden somit einen Doppelkolben 61. Der Raum 65 führt über einen Durchgang 41 zu einem Rückschlagventil 7, das einen Verschlusskörper 42 aufweist, der gegen die rückwirkende Kraft einer Druckfeder 43 von einem Ventilsitz 66 abhebbar ist. Das Rückschlagventil 7 weist einen Anschlussstutzen 44 auf, an dem die zur Düse 11 führende Leitung 9 angeschlossen ist.The piston 30 is via a web 32 with a further down arranged piston 37 firmly connected. This piston 37 has a check valve 36, which is shown in FIG Position is open and the interior 64 with an interior 65 of the housing part 40 connects. When closed Valve 36 seals the piston 37 with a circumferential lip seal 38 the interior 65 against the room 64. The Both pistons 30 and 37 thus form a double piston 61. The space 65 leads through a passage 41 to a check valve 7, which has a closure body 42 which against the retroactive force of a compression spring 43 by one Valve seat 66 can be lifted off. The check valve 7 has a connecting piece 44 on which the leading to the nozzle 11 Line 9 is connected.

Strömt durch das geöffnete Einlaufventil 4 Druckwasser in den Raum 5, so wird durch den Druck dieses Wassers der Kolben 61 gegen die rückwirkende Kraft einer Druckfeder 39 nach unten bewegt. Der Raum 65 ist mit Wasser gefüllt, das durch den sich nach unten bewegenden Kolben 37 unter Druck gesetzt wird und das Rückschlagventil 36 schliesst. Der Wasserdruck im Raum 65 steigt mit dem sich nach unten bewegenden Kolben 37 stetig an, bis bei einem bestimmten Druck das Rückschlagventil 7 geöffnet wird und durch den Durchgang 41 Wasser in die Leitung 9 und schliesslich zur Düse 11 gelangen kann. Der Kolben 37 bewegt sich nach unten, bis er an einer ringförmigen Fläche 67 ansteht und eine vorbestimmte Wassermenge aus dem Raum 65 bei einem vorbestimmten Fliessdruck verdrängt ist.4 pressurized water flows in through the opened inlet valve space 5, the pressure of this water causes the piston 61 against the retroactive force of a compression spring 39 moved down. The room 65 is filled with water that by the piston 37 moving downward under pressure is set and the check valve 36 closes. Of the Water pressure in room 65 increases with the downward movement Piston 37 steadily on until at a certain pressure the check valve 7 is opened and through the passage 41 water into line 9 and finally to the nozzle 11 can reach. The piston 37 moves down until it rests on an annular surface 67 and a predetermined one Amount of water from the room 65 at a predetermined Flow pressure is displaced.

Bevor der Kolben 37 an der Fläche 67 ansteht, überfährt die Lippendichtung 31 mehrere Durchgangslöcher 34 des Gehäuses 33. Befindet sich somit der Kolben 37 in seiner unteren Stellung, so strömt von der Kammer 5 durch die Durchgangsöffnungen 34 Wasser nach aussen in den Spülkasten und füllt diesen bis zum Erreichen des Wasserstandes A wieder auf. Durch einen aussen am Gehäuse 33 angebrachten Ring 35 wird das durch die Löcher 34 ausströmende Wasser geräuscharm nach unten gelenkt.Before the piston 37 abuts the surface 67, it runs over Lip seal 31 a plurality of through holes 34 of the housing 33. The piston 37 is thus in its lower one Position, flows from the chamber 5 through the through openings 34 Water out into the cistern and fill this again until the water level A is reached. By a ring 35 attached to the outside of the housing 33 the water flowing out through the holes 34 is quiet steered down.

Durch Bohrungen 69 wird die Kammer 65 wieder mit Wasser gefüllt, wobei der Zylinder 37 wieder in die in Fig. 2 gezeigte Ausgangsstellung bewegt wird.Through holes 69 is the Chamber 65 again filled with water, the cylinder 37 moved back to the starting position shown in Fig. 2 becomes.

Erreicht beim Auffüllen des Spülkastens das Wasser die Höhe des Rückschlagventils 22, so erfährt ein Verschlusskörper 68 einen Auftrieb, wodurch dieses Ventil geschlossen wird. Der Schwimmer 21 verbleibt dadurch in seiner unteren Stellung, bis das Wasser 50 den Wasserstand A erreicht hat. Entsprechend bleibt das Einlaufventil 4 offen, bis der Spülkasten vollständig wieder aufgefüllt ist. Beim Erreichen des Wasserstandes A gelangt Wasser über die obere Kante des Gefässes 20 in dieses, bis es schliesslich wieder mit Wasser gefüllt ist und der Schwimmer 21 die Ventilstange 24 nach oben bewegt und die Durchgangsöffnung 25 schliesst. Damit ist wieder der in Fig. 2 gezeigte Zustand erreicht, bei dem der Spülkasten für eine weitere Spülung bereit ist. Wie aus Fig. 2 ersichtlich, ist eine Ueberlaufkante 71 des Ventilrohrs 16 etwa 2 cm tiefer angeordnet als die Löcher 34 im Gehäuse 33. Dadurch wird eine sogenannte Wassertrennung erreicht, welche die Wirkung eines Rohrunterbrechers besitzt und ein Rücksaugen von Schmutzwasser in das Leitungswasser verhindert.When the cistern is filled, the water reaches the height of the check valve 22, so experiences a closure body 68 a buoyancy, whereby this valve is closed. The float 21 thereby remains in its lower position, until the water 50 has reached water level A. Accordingly, the inlet valve 4 remains open until the Cistern is completely refilled. When reaching of water level A, water reaches the upper one Edge of the vessel 20 into this until it finally comes back is filled with water and the float 21 the valve rod 24 moves upward and the through opening 25 closes. This is the state shown in FIG. 2 again reached, where the cistern for another flush ready. As can be seen from FIG. 2, there is an overflow edge 71 of the valve tube 16 arranged about 2 cm lower than the holes 34 in the housing 33. This creates a so-called Water separation is achieved, which is the effect of a pipe interrupter owns and suck back dirty water in the tap water prevented.

Der Steuerschwimmer gemäss Fig. 4 zeigt den Ruhezustand des Spülkastens. In diesem Zustand sind das Einlaufventil 4, das Auslaufventil 13 geschlossen und das Zylinderfüllventil 69 geöffnet. Der Druck in der Versorgungsleitung 2 beträgt beispielsweise 1 bis 10 bar. Wird nun zum Spülen das Ablaufventil 13 geöffnet, so fliesst mit der üblichen Spülleitung Wasser in den Rohrbogen 12. Das Rückschlagventil 22 der Steuervorrichtung 54 ist so eingestellt, dass der Schwimmer 21 erst dann nach unten fährt, wenn das Wasser 50 den in Fig. 2 den mit B markierten Wasserstand erreicht hat. Bei diesem Wasserstand B wird das Einlaufventil 4 sofort geöffnet und aus der Kammer 65 Wasser in die Leitung 9 verdrängt. Die durch die Steuervorrichtung 54 bewirkte Zeitverzögerung ist so eingestellt, dass durch die Düse 11 dann Spülwasser abgegeben wird, wenn das durch den Kanal 51 in das Becken 56 einfliessende Wasser den Bogen 46 erreicht hat. Diesem Zustand entspricht das Steuerschema gemäss Fig. 5. Bei diesem sind das Ablaufventil 13, das Einlaufventil 4 als auch das Rückschlagventil 7 geöffnet. Die Zeitdauer während der durch die Düse 11 Wasser abgegeben wird, ist vergleichsweise kurz.4 shows the idle state of the Cistern. In this state, the inlet valve 4, the outlet valve 13 closed and the cylinder fill valve 69 open. The pressure in the supply line 2 is for example 1 to 10 bar. Now the drain valve for rinsing 13 opened, flows with the usual flushing line Water in the elbow 12. The check valve 22 of the control device 54 is set so that the Float 21 only goes down when the water 50 reached the water level marked B in FIG. 2 Has. At this water level B, the inlet valve 4 is immediately opened and water from chamber 65 into line 9 repressed. The one caused by the control device 54 The time delay is set such that through the nozzle 11 then rinse water is dispensed when that through the channel 51st water flowing into the basin 56 reaches the arch 46 Has. The control scheme according to FIG. 5. In this are the drain valve 13, the inlet valve 4th as well as the check valve 7 opened. The length of time during which water is discharged through the nozzle 11 comparatively short.
