Abstract

A toilet-tank discharge valve has a main-valve body that can be lifted off of its face, by release-activating an auxiliary valve with an activating mechanism, as a consequence of negative water balance in an associated discharge compartment. A supplementary auxiliary valve is associated with the discharge compartment and opens at least briefly as a result of discontinuance activation of the activating mechanism, producing a positive water balance in the discharge compartment until the main-valve body closes. A valve of this type, with an auxiliary valve, makes it possible to discontinue the flushing process ahead of time. A shift mechanism in the connection between the activating mechanism and the supplementary auxiliary valve shifts the supplementary auxiliary valve from whatever limiting position it happens to be in into the opposite limiting position in response to a discontinuance activation. This makes it possible for both release and discontinuation activation to be initiated with uniform pressure strokes. This not only makes the device easier to operate but also makes remote activation possible with simple devices.

Description

Die Erfindung betrifft ein Spülkasten-Ablaufventil mit einem Hauptventilkörper, der durch die Auslöse-Betätigung eines Hilfsventils mittels einer Betätigungseinrichtung infolge einer sich einstellenden negativen Wasserbilanz in einer ihm zugeordneten Entlastungskammer von seinem Sitz abhebbar ist.The invention relates to a cistern drain valve with a main valve body, which can be lifted off its seat by the triggering actuation of an auxiliary valve by means of an actuating device as a result of a negative water balance in an associated relief chamber.

Eine derartige Armatur ist beispielsweise aus der DE-A-26 09138 bekannt. Die Oberseite des dort vorgesehenen Hauptventilkörpers bildet die untere Begrenzung einer Entlastungskammer. Von der Entlastungskammer führt in den Spülkastenabgang ein Strömungskanal, in dem das Hilfsventil angeordnet ist. Mit der ersten Betätigung des gefüllten Spülkastens, der Auslöse- Betätigung, wird das Hilfsventil geöffnet. Das aus der Entlastungskammer ablaufende Wasser erzeugt in ihr eine negative Wasserbilanz. Als Folge hebt der Hauptventilköper von seinem Sitz ab.Such a fitting is known for example from DE-A-26 09138. The top of the main valve body provided there forms the lower boundary of a relief chamber. A flow channel in which the auxiliary valve is arranged leads from the relief chamber into the cistern outlet. With the first actuation of the filled cistern, the trigger actuation, the auxiliary valve is opened. The water running out of the relief chamber creates a negative water balance in it. As a result, the main valve body lifts off its seat.

Derartige Ablaufventile ermöglichen es bislang nicht, den eingeleiteten Spülgang zu unterbrechen. Mit jeder Betätigung kommt es somit stets zur vollständigen Entleerung des Spülkastens.Such drain valves have so far not made it possible to interrupt the flushing process that has been initiated. With each actuation, the cistern is always completely emptied.

Wegen der immer dringlicheren Forderung nach Wasserersparnis liegt der vorliegenden Erfindung die Aufgabe zugrunde, ein Ablaufventil der gattungsgemäßen Art zu schaffen, bei dem der eingeleitete Spülvorgang durch eine zweite Betätigung unterbrechbar ist. Diese Unterbrechungsbetätigung soll mit der vorhandenen Betätigungseinrichtung durchführbar sein.Because of the increasingly urgent demand for water savings, the present invention has for its object to provide a drain valve of the generic type, in which the flushing process initiated can be interrupted by a second actuation. This interruption actuation should be able to be carried out with the existing actuation device.

Die erfindungsgemäße Lösung ergibt sich aus dem kennzeichnenden Teil des Patentanspruches 1.The solution according to the invention results from the characterizing part of patent claim 1.

Durch das Zusatz-Hilfsventil, das durch eine Unterbrechungs-Betätigung der Betätigungseinrichtung mindestens kurzfristig zu öffnen ist, wird in der Entlastungskammer eine positive Wasserbilanz im Sinne der Schließung des Hauptventilkörpers erreicht und bis zum endgültigen Abschluß des Hauptventilkörpers auch aufrechterhalten.The additional auxiliary valve, which can be opened at least for a short time by interrupting the actuating device, achieves a positive water balance in the relief chamber in the sense of the closure of the main valve body and also maintains it until the main valve body is finally closed.

Durch diese Ausgestaltung ist die vorzeitige Unterbrechung des Spülvorganges möglich, und zwar auch mit hohem Bedienungskomfort, da die Betätigungskräfte und -hübe gering gehalten werden können und die Unterbrechungs-Betätigung in gleicher Weise erfolgt wie die Auslöse- Betätigung.This configuration enables the purging process to be interrupted prematurely, even with a high level of operating convenience, since the actuation forces and strokes can be kept low and the interruption actuation takes place in the same way as the trigger actuation.

Weitere Ausgestaltungen des Erfindungsgedankens sind in den Unteransprüchen gekennzeichnet. So besteht die Möglichkeit, das Zusatz-Hilfsventil im Vergleich zum Hilfsventil mit einem größeren Strömungsquerschnitt auszführen und dafür zu sorgen, daß es durch die Unterbrechungs-Betätigung öffnet und nicht früher als das Hilfsventil schließt. Hierbei ist es zweckmäßig, daß eine Schalteinrichtung in der Verbindung zwischen der Betätigungseinrichtung und dem Zusatz-Hilfsventil so ausgebildet ist, daß durch die Unterbrechungs-Betätigung das Zusatz-Hilfsventil von der angetroffenen Endstellung in die entgegengesetzte Endstellung bewegbar ist. Es besteht allerdings auch eine weitere grundsätzliche Möglichkeit, durch die Unterbrechungs-Betätigung das Zusatz-Hilfsventil nur kurzzeitig zu öffnen und gleichzeitig die Strömung durch das Hilfsventil durch eine bis zum endgültigen Abschluß des Hauptventilkörpers selbsthaltende Sperre weitgehend zu drosseln. Mit diesen Ausgestaltungen können sowohl die Auslöse- als auch die Unterbrechungs-Betätigung mit gleichgerichteten Druckhüben ausgeführt werden. Dies erhöht nicht nur den Bedienungskomfort, es können für Fernbetätigungen auch die bislang üblichen Vorrichtungen, die im allgemeinen nur eine Wirkungsrichtung zulassen, übernommen werden.Further refinements of the inventive concept are characterized in the subclaims. It is thus possible to design the auxiliary auxiliary valve with a larger flow cross section than the auxiliary valve and to ensure that it opens by the interruption actuation and does not close earlier than the auxiliary valve. It is expedient that a switching device in the connection between the actuating device and the auxiliary auxiliary valve is designed such that the auxiliary auxiliary valve can be moved from the end position encountered into the opposite end position by the interruption actuation. However, there is also a further basic possibility of opening the auxiliary auxiliary valve only briefly by the interruption actuation and at the same time largely restricting the flow through the auxiliary valve by means of a lock which is self-locking until the main valve body is finally closed. With these configurations, both the triggering and the interruption actuation can be carried out with rectified pressure strokes. This not only increases the ease of use, it can also be used for remote controls, the devices that were previously common, which generally only allow one direction of action.

Die Schalteinrichtung für die Ansteuerung des Zusatz-Hilfsventils kann insbesondere auch ein Binär-Untersetzer sein. Mit dem Patentanspruch 5 ist ein besonderer Binär-Untersetzer gekennzeichnet, der vergleichsweise geringe Betätigungshübe zuläßt und in unbetätigtem Zustand auch schon durch besonders geringe Kräfte bezüglich seiner Endstellung umschaltbar ist. Diese Ausgestaltung eines Binär-Untersetzers wird für sich genommen als erfinderisch angesehen.The switching device for controlling the auxiliary auxiliary valve can in particular also be a binary coaster. The patent claim 5 is a special binary coaster, which allows comparatively small actuation strokes and can be switched over in its unactuated state even by particularly low forces with regard to its end position. This embodiment of a binary coaster is considered in itself to be inventive.

Embodiments of cistern drain valves according to the invention are described below with reference to the drawings. It shows

  • 2 shows the drain valve according to FIG. 1 during the rinsing process,

Die Fig. 1 und 2 zeigen ein Ablaufventil mit seiner aus dem Kastendeckel hervorragenden Betätigungsstange 1. Diese ist fest mit der Ventilglocke 2 verbunden, die sich über die vorgespannten seitlichen Federn 3 am Kastenboden abstützt. In der Ventilglocke 2 befindet sich der aufwärts bewegbare Hauptventilkörper 4, der bei gefülltem und spülbereiten Kasten (Fig. 1) sowohl das untere Hauptventil als auch das mittige Hilfsventil 8 verschließt. Die Oberseite des Hauptventilkörpers 4 und die Ventilglocke 2 begrenzen die Entlastungskammer 6. Das Hilfsventil 8, das den Strömungskanal zwischen der Entlastungskammer 6 und dem Spülkastenabgang 5 verschließt, wird von einer in den Hauptventilkörper 4 eingelegten Dichtscheibe sowie dem Endflansch der Betätigungsstange 1 gebildet.1 and 2 show a drain valve with its actuating rod 1 protruding from the box lid. This is firmly connected to the valve bell 2, which is supported on the box bottom by means of the prestressed lateral springs 3. In the valve bell 2 there is the upwardly movable main valve body 4, which closes both the lower main valve and the central auxiliary valve 8 when the box is filled and ready for rinsing (FIG. 1). The top of the main valve body 4 and the valve bell 2 delimit the relief chamber 6. The auxiliary valve 8, which closes the flow channel between the relief chamber 6 and the cistern outlet 5, is formed by a sealing washer inserted into the main valve body 4 and the end flange of the actuating rod 1.

In der oberen Wand der Entlastungskammer ist das Zusatz-Hilfsventil 9 angeordnet, das von einer mit einem Wanddurchbruch zusammenwirkenden Schwimmerklappe 11 gebildet wird. Sein Strömungsquerschnitt ist größer als der des Hilfsventils 8. Die Schwimmerklappe 11 befindet sich am linken Arm des Steuerhebels 10, dessen Lagerzapfen 15 fest mit der Ventilglocke 2 verbunden ist. Am rechten Arm befindet sich ein in die Entlastungskammer 6 eintretender Stöße! 12 und mittig der Steuerarm 13.In the upper wall of the relief chamber, the auxiliary auxiliary valve 9 is arranged, which cooperates with a wall opening kenden float flap 11 is formed. Its flow cross section is larger than that of the auxiliary valve 8. The float flap 11 is located on the left arm of the control lever 10, the bearing pin 15 of which is firmly connected to the valve bell 2. On the right arm there is a shock entering the relief chamber 6! 12 and in the middle the control arm 13.

Der Steuerarm 13, der sich mit jeder Betätigung relativ zum ortsfesten Steuergehäuse 14 bewegt, bildet mit diesem eine Schalteinrichtung, die z. B. wie der später beschriebene Binär-Untersetzer ausgebildet sein kann. Die Schalteinrichtung 13, 14 bewirkt, daß die jeweils bei einer Betätigung angetroffene Endstellung des Steuerhebels 10 in die entgegengesetzte Endstellung geschwenkt wird. In unbetätigtem Zustand behindert das Steuergehäuse 14 den Steuerarm 13 nicht, so daß der Steuerhebel 10 - je nach Richtung der auf ihn einwirkenden Kräfte - entweder in der nach der Betätigung erreichten Endstellung verbleibt oder in die entgegengesetzte Endstellung zurückgeschwenkt wird.The control arm 13, which moves with each actuation relative to the stationary control housing 14, forms with this a switching device which, for. B. how the binary coaster described later can be designed. The switching device 13, 14 has the effect that the end position of the control lever 10 which is encountered in each actuation is pivoted into the opposite end position. In the unactuated state, the control housing 14 does not hinder the control arm 13, so that the control lever 10 - depending on the direction of the forces acting on it - either remains in the end position reached after actuation or is pivoted back into the opposite end position.

In Fig. 1 ist die Ausgangsstellung des Ablaufventils bei gefülltem und spülbereitem Kasten dargestellt. Das Hauptventil und das Hilfsventil 8 sind geschlossen. Durch den Auftrieb der Schwimmerklappe 11 ist das Zusatz-Hilfsventil 9 geöffnet, womit der Steuerarm 13 seine rechte Endstellung einnimmt. Mit der Auslöse-Betätigung bewegt sich der Steuerarm 13 relativ zum Steuergehäuse 14, das ihn in seine linke Endstellung schwenkt. Das Zusatz-Hilfsventil 9 schließt. Da sich gleichzeitig das Hilfsventil 8 öffnet, wird die Wasserbilanz in der Entlastungskammer negativ. Der Hauptventilkörper 4 hebt von seinem Sitz ab und der Spülvorgang setzt ein. Diese Bewegungsabläufe sind durch die in Fig. 1 eingezeichneten Pfeile verdeutlicht.In Fig. 1 the starting position of the drain valve is shown when the box is filled and ready for rinsing. The main valve and the auxiliary valve 8 are closed. Due to the buoyancy of the float flap 11, the auxiliary auxiliary valve 9 is opened, whereby the control arm 13 assumes its right end position. With the trigger actuation, the control arm 13 moves relative to the control housing 14, which pivots it into its left end position. The auxiliary auxiliary valve 9 closes. Since the auxiliary valve 8 opens at the same time, the water balance in the relief chamber becomes negative. The main valve body 4 lifts off its seat and the flushing process begins. These movement sequences are illustrated by the arrows drawn in FIG. 1.

Die Schwimmerklappe 11 kann auch ohne eine zwangsweise Steuerung durch die Schalteinrichtung 13, 14 in ihre Schließstellung bewegt werden. Hierzu ist sie so auszubilden, daß sie trotz ihrer Antriebskraft mit der durch das Hilfsventil 8 einsetzenden Strömung, die sich zwangläufig auch am Zusatz-Hilfsventil 9 einstellt, zugerissen wird. Dies wird später näher beschrieben.The float flap 11 can also be moved into its closed position without forced control by the switching device 13, 14. For this purpose, it is to be designed in such a way that, despite its driving force, it is torn with the flow through the auxiliary valve 8, which inevitably also occurs at the auxiliary auxiliary valve 9. This will be described in more detail later.

Fig. 2 zeigt das Ablaufventil nach der Auslöse- Betätigung während des Spülvorganges. Die in Schließrichtung wirkende Druckdifferenz am Zusatz-Hilfsventil 9 bleibt erhalten, so daß die Schwimmerklappe 11 trotz ihrer Auftriebskraft weiterhin geschlossen bleibt. Erfolgt keine Unterbrechungs-Betätigung schließt der Hauptventilkörper 4 erst nach Ablauf des Kasteninhalts. Anschließend wird das über das Füllventil zufließende Wasser erneut aufgestaut. Wenn der Wasserstand die Schwimmerklappe 11 übersteigt, sorgt deren Auftriebskraft für die Rückstellung des Steuerhebels 10 in die in Fig. 1 dargestellte Ausgangslage, so daß der Kasten wieder spülbereit ist.Fig. 2 shows the drain valve after the trigger actuation during the flushing process. The pressure difference acting in the closing direction on the auxiliary auxiliary valve 9 is maintained, so that the float valve 11 remains closed despite its buoyancy. If there is no interruption actuation, the main valve body 4 only closes after the contents of the box have expired. The water flowing in via the filling valve is then dammed up again. When the water level exceeds the float flap 11, its buoyancy provides for the return of the control lever 10 to the starting position shown in Fig. 1, so that the box is ready for washing again.

Ausgehend von dem in Fig. 2 dargestellten Zustand bewirkt eine Unterbrechungs-Betätigung die erneute Relativbewegung zwischen Steuergehäuse 14 und Steuerarm 13. Dieser wird daher in seine rechte Endstellung zurückgeschwenkt. Das Zusatz-Hilfsventil 9 öffnet. Gleichzeitig drückt der Stößel 12 den Hauptventilkörper 4 nach unten. Dies ist theoretisch nicht erforderlich, dient also lediglich der Unterstützung der Schließbewegung und kann sich ohne weiteres auch nur auf den Anfangsbereich des Schließhubes beschränken. Damit ereicht man jedoch, daß der Hauptventilkörper 4 noch stärker in den Sog des ablaufenden Spülwassers gerät und seine Schwimmkraft durch die nach unten wirkenden Strömungskräfte besser überwunden wird.Starting from the state shown in FIG. 2, an interruption actuation causes the relative movement between the control housing 14 and the control arm 13 again. This is therefore pivoted back into its right-hand end position. The auxiliary auxiliary valve 9 opens. At the same time, the plunger 12 presses the main valve body 4 down. Theoretically, this is not necessary, it only serves to support the closing movement and can easily be limited to the initial area of the closing stroke. However, this means that the main valve body 4 gets even more into the suction of the flushing water flowing off and its floating force is better overcome by the downward flow forces.

Entscheidend für das vorzeitige Schließen des Hauptventilkörpers 4 ist das Öffnen des Zusatz-Hilfsventils 9. Da sein Strömungsquerschnitt größer ist als der des noch immer offenen Hilfsventils 8, stellt sich in der Entlastungskammer 6 die erforderliche positive Wasserbilanz ein. Diese bleibt selbst dann erhalten, wenn mit dem Rückhub der Betätigungsstange 1 das Hilfsventil 8 und das Zusatz-Hilfsventil 9 synchron schließen. Verantwortlich dafür sind nicht nur der größere Strömungsquerschnitt des Zusatz-Hilfsventils 9, sondern auch die zwar geringfügigen, aber stets vorhandenen Strömungsquerschnitte, die mit dem Führungsspalt zwischen Hauptventilkörper 4 und der Ventilglocke 2 gegeben sind. Bei vollständigem Rückhub der Betätigungsstange 1 kommt der Hauptventilkörper 4 zum endgültigen Abschluß.The decisive factor for the premature closing of the main valve body 4 is the opening of the additional auxiliary valve 9. Since its flow cross-section is larger than that of the still open auxiliary valve 8, the required positive water balance is established in the relief chamber 6. This is retained even if the auxiliary valve 8 and the auxiliary auxiliary valve 9 close synchronously with the return stroke of the actuating rod 1. Responsible for this are not only the larger flow cross section of the auxiliary auxiliary valve 9, but also the flow cross sections, which are small but always present, and which are provided with the guide gap between the main valve body 4 and the valve bell 2. When the actuating rod 1 returns completely, the main valve body 4 comes to a final conclusion.

Andererseits kann man auch auf den Wanddurchbruch des Zusatz-Hilfsventils 9, also dessen Strömungsquerschnitt, verzichten. In diesem Fall muß der mit der Unterbrechungs-Betätigung in den Entlastungsraum 6 hineinbewegbare Stö- βel 12 den vollen Schließhub des Hauptventilkörpers 4 bewirken. Wegen der fehlenden hydraulischen Schließunterstützung ist dabei eine höhere Stößelkraft erforderlich, um den Auftrieb des Hauptventilkörpers 4 zu überwinden. Vorzugsweise kann auch für diese Ausgestaltung die Schalteinrichtung 13, 14 übernommen werden, wenn der den Steuerarm 13 tragende Lagerzapfen 15 ortsfest und das Steuergehäuse 14 mit der Betätigung bewegbar angeordnet sind.On the other hand, you can also do without the wall opening of the auxiliary auxiliary valve 9, that is to say its flow cross section. In this case, the plunger 12 which can be moved into the relief chamber 6 with the interruption actuation must bring about the full closing stroke of the main valve body 4. Because of the lack of hydraulic closing support, a higher tappet force is required to overcome the buoyancy of the main valve body 4. Preferably, the switching device 13, 14 can also be taken over for this embodiment if the bearing journal 15 carrying the control arm 13 is arranged in a stationary manner and the control housing 14 is movably arranged with the actuation.

Die Schalteinrichtung 13, 14 kann z. B. ein besonderer Binär-Untersetzer sein, der einen vergleichsweise geringen Betätigungshub benötigt, und der in unbetätigtem Zustand keine Kräfte auf den Steuerhebel 10 ausübt. Er wird nachstehend anhand der Fig. 3 und 4 beschrieben.The switching device 13, 14 can, for. B. be a special binary coaster, which requires a comparatively small actuation stroke, and which exerts no forces on the control lever 10 in the unactuated state. It is described below with reference to FIGS. 3 and 4.

In Fig. 3 ist der symmetrisch aufgebaute Steuerarm 13 (entspricht dem symbolischen Steuerarm 13 der Fig. 1 und 2) in seiner rechten Endlage in ausgezogener Linie dargestellt. Sein Lagerzapfen 15 bewegt sich mit jeder Betätigung relativ zu den ebenfalls symmetrischen ortsfesten Steuerkonturen (entspricht dem Steuergehäuse 14 der Fig. 1 und 2). An den Enden des Steuerarmes 13 sind jeweils über elastische Verbindungszonen 16 die Hebelarme 17 befestigt, die jeweils am oberen Ende den rechten Steuerzapfen 19 und den linken Steuerzapfen 20 tragen. Diese arbeiten mit den ortsfesten Steuerkanten 21 und deren Anlaufschrägen 22 zusammen. Der Mittelarm 23 trägt am oberen Ende den Steuerzapfen 24, der mit den ortsfesten Steuerkanten 25 und deren Anlaufschrägen 26 zusammenwirkt. Die die Steuerzapfen tragenden Arme sind jeweils senkrecht zur Zeichenebene elastisch, so daß die Ablaufschrägen keine Behinderung darstellen.In Fig. 3 the symmetrical control arm 13 (corresponds to the symbolic control arm 13 of Figs. 1 and 2) is shown in its right end position in a solid line. Its journal 15 moves with each actuation relative to the likewise symmetrical fixed control contours (corresponds to the control housing 14 in FIGS. 1 and 2). At the ends of the control arm 13, the lever arms 17 are each attached via elastic connecting zones 16, each carrying the right control pin 19 and the left control pin 20 at the upper end. These work together with the fixed control edges 21 and their run-on slopes 22. The center arm 23 carries at the upper end the control pin 24, which cooperates with the fixed control edges 25 and their run-up slopes 26. The arms carrying the control pins are each elastic perpendicular to the plane of the drawing, so that the run-off slopes do not constitute an obstacle.

Bewegt sich bei einer Betätigung der Lagerzapfen 15 gemäß Pfeil nach unten, schwenkt der Steuerarm 13 um seine rechte elastische Verbindungszone, da hier die Abwärtsbewegung durch den hinter die Steuerkante 21 greifenden Steuerzapfen 19 behindert wird. Auf dem Weg zu der in Fig. 3 gestrichelt dargestellten Endlage gleitet der Steuerzapfen 24 des Mittelarmes 23 über die Anlaufschrägen 26 der Steuerkante 24 und rastet hinter dieser ein.If the pivot pin 15 moves downward when the pivot pin 15 is actuated, the control arm 13 pivots about its right elastic connecting zone, since here the downward movement is hindered by the control pin 19 reaching behind the control edge 21. On the way to the end position shown in dashed lines in FIG. 3, the control pin 24 of the center arm 23 slides over the run-up bevels 26 of the control edge 24 and engages behind it.

Diese Endlage ist die in Fig. 4 in ausgezogener Linie dargestellte Ausgangslage für den folgenden Rückhub der Betätigung und damit des Lagerzapfens 15. Dabei gleitet der Steuerzapfen 24 hinter seiner Steuerkante 25 nach oben und verriegelt die linke Endstellung des Steuerarmes 13. Der rechte Steuerzapfen 19 löst sich von seiner Steuerkante 21 und federt in seine ursprüngliche Relativstellung zum Steuerarm 13 zurück. In der Endphase des Rückhubes gleitet der linke Steuerzapfen 20 auf die Anlaufschräge 22, deren hochstehende rechte Begrenzungskante die Verriegelung der Schwenkstellung übernimmt, bevor der Steuerzapfen 24 seine Steuerkante 25 verläßt. Die Endstellung des Rückhubes ist in Fig. 4 gestrichelt dargestellt. Der linke Steuerzapfen ist hinter die Steuerkante 21 eingerastet.This end position is the starting position shown in solid line in FIG. 4 for the subsequent return stroke of the actuation and thus the bearing pin 15. The control pin 24 slides upward behind its control edge 25 and locks the left end position of the control arm 13. The right control pin 19 releases from its control edge 21 and springs back into its original relative position to the control arm 13. In the final phase of the return stroke, the left control pin 20 slides onto the run-up slope 22, the upright right-hand boundary edge of which takes over the locking of the swivel position before the control pin 24 leaves its control edge 25. The end position of the return stroke is shown in dashed lines in FIG. 4. The left control pin is locked behind the control edge 21.

Wegen des symmetrischen Aufbaues des beschriebenen Binär-Untersetzers bewirkt ein erneuter Doppelhub den entgegengesetzten Bewegungsablauf, also ein Zurückschwenken des Steuerarms 13 in die ursprüngliche Ausgangsstellung.Because of the symmetrical structure of the binary reducer described, a renewed double stroke effects the opposite movement sequence, that is, a pivoting back of the control arm 13 into the original starting position.

Die Steuerzapfen werden in den jeweiligen Endstellungen bei unbetätigtem Binär-Untersetzer nicht durch die ortsfesten Steuerkonturen behindert. Der Steuerarm 13 kann daher auch ohne erneuten Doppelhub durch von außen angreifende geringfügige Kräfte, die lediglich die Lagerreibung des Zapfens 15 überwinden müssen, in seine ursprüngliche Ausgangsstellung zurückgeschwenkt werden. Dies ist durch die nicht ausgefüllten Pfeile in Fig. 4 dargestellt.The control pins are not hindered by the fixed control contours in the respective end positions when the binary coaster is not actuated. The control arm 13 can therefore be pivoted back into its original starting position even without a renewed double stroke by minor forces acting from outside, which only have to overcome the bearing friction of the pin 15. This is shown by the unfilled arrows in FIG. 4.

Für die vorliegende Anwendung kann der Binär-Untersetzer so abgewandelt werden, daß mit der Auslöse-Betätigung der Steuerarm 13 nur durch hydraulische Kräfte in seine entgegengesetzte Endstellung geschwenkt wird. Diese hydraulischen Kräfte sind insofern wirksam, als die mit der Auslöse-Betätigung durch das Hilfsventil einsetzende Strömung sich zwangläufig auch am Zusatz-Hilfsventil einstellt und die Schwimmerklappe in Schließrichtung bewegt. Zur Unterstützung dieser Schließbewegung, die gegen die Auftriebskraft der Schwimmerklappe 11 erfolgen muß, kann eine ortsfeste Steuerkante 18 angeordnet sein, die in Fig. 3 als punktierte Linie dargestellt ist. Sie wirkt auf den Steuerzapfen 20 und leitet die Linksschwenkung des Steuerarmes 13 ein. Eine derart vereinfachte Schalteinrichtung 13, 14 kann daher im Vergleich zum vollständigen Binär-Untersetzer auf den rechten und mittleren Steuerarm sowie die mit ihnen zusammenwirkenden ortsfesten Steuerkonturen verzichten.For the present application, the binary coaster can be modified such that the control arm 13 is pivoted into its opposite end position only by hydraulic forces when the trigger is actuated. These hydraulic forces are effective insofar as the flow that begins with the actuation of the trigger by the auxiliary valve also inevitably occurs at the auxiliary auxiliary valve and moves the float valve in the closing direction. To support this closing movement, which must take place against the buoyancy of the float flap 11, a fixed control edge 18 can be arranged, which is shown in FIG. 3 as a dotted line. It acts on the control pin 20 and initiates the left pivoting of the control arm 13. Such a simplified switching device 13, 14 can therefore dispense with the right and middle control arm and the fixed control contours interacting with them in comparison to the complete binary coaster.

Bei dem in den Fig. 5 und 6 dargestellten Ausführungsbeispiel eines Ablaufventils gemäß der Erfindung ist bei vergleichbarem Aufbau die Unterbrechbarkeit des Spülvorganges und die Wiederherstellung der Spülbereitschaft auf grundsätzlich andere Weise insbesondere ohne die Schalteinrichtung 13,14 erreicht.In the embodiment of a drain valve according to the invention shown in FIGS. 5 and 6, the interruption of the rinsing process and the restoration of the rinsing readiness are achieved in a fundamentally different way, in particular without the switching device 13, 14, with a comparable structure.

Die Ventilglocke 2 und die Betätigungsstange 1 sind baulich voneinander getrennt. Sie werden aber durch eine Druckfeder 27 gegeneinander fixiert, deren Vorspannung stärker ist als die der vorgespannten seitlichen Federn 3. Das zur Entlastungskammer 6 führende Zusatz-Hilfsventil 9' wird durch den an der Betätigungsstange 1 angeordneten Flansch 28 und durch den mit ihm zusammenwirkenden Innenkragen der Ventilglocke 2 gebildet. Weiterhin ist im Bereich der Entlastungskammer 6' auf der Betätigungsstange 1 der Hilfsschwimmer 29 geführt, dessen unterer Außendurchmesser etwas größer ist als der Durchmesser des Innenkragens 30 in der Mittelbohrung des Hauptventilkörpers 4.The valve bell 2 and the actuating rod 1 are structurally separate from one another. However, they are fixed against each other by a compression spring 27, the pretension of which is stronger than that of the pretensioned lateral springs 3. The auxiliary auxiliary valve 9 'leading to the relief chamber 6 is replaced by the flange 28 arranged on the actuating rod 1 and by the inner collar cooperating with it Valve bell 2 formed. Furthermore, the auxiliary float 29 is guided in the area of the relief chamber 6 'on the actuating rod 1, the lower outer diameter of which is somewhat larger than the diameter of the inner collar 30 in the central bore of the main valve body 4.

Die Auslöse-Betätigung erfolgt in üblicher Weise. Wenn dabei nur die Rückstellkraft der seitlichen Federn 3 überwunden wird, nicht aber die Feder 27, bleibt das Zusatz-Hilfsventil 9' geschlossen. Das geöffnete Hilfsventil sorgt für eine negative Wasserbilanz in der Entlastungskammer 6 und der Hauptventilkörper 4 öffnet. Diese Bewegungsabläufe sind in Fig. 5 dargestellt.The triggering operation is carried out in the usual way. If only the restoring force of the lateral springs 3 is overcome, but not the spring 27, the auxiliary auxiliary valve 9 'remains closed. The opened auxiliary valve ensures a negative water balance in the relief chamber 6 and the main valve body 4 opens. These sequences of movements are shown in FIG. 5.

Fig. 6 zeigt die Unterbrechungs-Betätigung. Dabei muß die Rückstellkraft der Feder 27 überwunden werden, so daß das Zusatz-Hilfsventil 9' öffnet. Die Wasserbilanz in der Entlastungskammer 6 wird positiv und bewegt in Verbindung mit den verstärkt in Schließrichtung wirkenden Strömungskräften den Hauptventilkörper 4 nach unten. Ihm folgt der Hilfsschwimmer 29, der durch hydraulische Kräfte auf den Innenkragen 30 des Schwimmerkolbens 4 gedrückt wird und damit die Strömung durch das noch offene Hilfsventil 8 sperrt. Damit bleibt die positive Wasserbilanz bis zum endgültigen Abschluß des Ablaufventils selbst dann erhalten, wenn bei dem Rückhub der Unterbrechungs-Betätigung das Zusatz-Hilfsventil 9' früher als das Hilfsventil 8 schließt. Hierfür sorgen wieder die zusätzlichen Strömungsquerschnitte zwischen dem Außendurchmesser des Hauptventilkörpers 4 und der Innenwandung der Ventilglocke 2. Sie sind deutlich größer als der vergleichsweise enge Führungsspalt zwischen Hilfsschwimmer 29 und der Betätigungsstange 1.Fig. 6 shows the interrupt operation. The restoring force of the spring 27 must be overcome so that the auxiliary auxiliary valve 9 'opens. The water balance in the relief chamber 6 becomes positive and moves the main valve body 4 downward in connection with the flow forces acting increasingly in the closing direction. This is followed by the auxiliary float 29, which is pressed by hydraulic forces onto the inner collar 30 of the float piston 4 and thus blocks the flow through the still open auxiliary valve 8. Thus, the positive water balance is maintained until the drain valve is finally closed even if the auxiliary auxiliary valve 9 'closes earlier than the auxiliary valve 8 during the return stroke of the interruption actuation. This is again ensured by the additional flow cross sections between the outer diameter of the main valve body 4 and the inner wall of the valve bell 2. They are significantly larger than the comparatively narrow guide gap between the auxiliary float 29 and the actuating rod 1.

Mit dem endgültigen Abschluß des Ablaufventils ist auch das Hilfsventil 8 geschlossen. Der Hilfsschwimmer 29 bewegt sich wegen seiner Auftriebskraft nach oben, da sich das ursprünglich an ihm wirkende Druckgefälle über seinen mittleren Führungsspalt ausgleichen kann. Damit ist der Spülkasten wieder für die nächste Auslöse-Betätigung bereit.With the final completion of the drain valve, the auxiliary valve 8 is also closed. The Auxiliary float 29 moves upwards because of its buoyancy, since the pressure drop originally acting on it can be compensated for via its central guide gap. The cistern is now ready for the next actuation.

Es liegt auf der Hand, daß die dargestellten Ausführungsbeispiele nur einen Bruchteil der Möglichkeiten wiedergeben, den Grundgedanken der Erfindung zu realisieren.It is obvious that the exemplary embodiments shown represent only a fraction of the possibilities for realizing the basic idea of the invention.
