Abstract

The outlet valve for a cistern has the lifting mechanism (4) at the overflow pipe (3) area. The base valve (2) is held open during flushing by a retainer (5) controlled by a float. For a full flushing action, the first float (50) alone controls the retainer. For partial flushing, a second float (60) is activated over the first float so that, at the end of the partial flushing, it acts on the first float (50) to release the retainer which holds the base valve open.

Bei dem in der Zeichnung gezeigten Ausführungsbeispiel ist die Auslaufarmatur in einem nur schematisch und zum Teil dargestellten Spülkasten 1 angeordnet, wobei die Wasserzulaufeinrichtung nicht gezeigt ist. Im Bodenbereich ist eine Auslaßöffnung ausgebildet, in dem ein Bodenventil 2 in bekannter Weise gedichtet angeordnet ist. An dem am Bodenventil 2 ausgebildeten Auslaßstutzen 20 wird die Spülleitung angeschlossen (in der Zeichnung nicht dargestellt). Im Inneren des Spülkastens 1 ist das Bodenventil 2 mit einem im Durchmesser vergrößerten Kragen 21 ausgebildet, in dessen Seitenwandung Wassereinlaßschlitze 210 angeordnet sind.
Koaxial zum Bodenventil 2 ist ein Überlaufrohr 3 angeordnet, das am unteren Endbereich ein ringflanschartig ausgebildetes Verschlußglied 31 trägt, an dem ein Dichtring 310 mit Hilfe eines Stützrings 33 angelagert ist, derart, daß in abgesenkter Stellung das Überlaufrohr 3 den Ausfluß in den Auslaßstutzen 20 absperrt.
Koaxial zum Überlaufrohr 3 ist im wesentlichen im Innern des Überlaufrohrs 3 eine Aushebevorrichtung 4 angeordnet. Im unteren Bereich ist hierbei die Aushebevorrichtung 4 mit einem Ansatz konzentrisch im Anschlußstutzen 20 gehalten. An der gegenüberliegenden Seite weist die Aushebevorrichtung 4 eine Muffe 41 mit Innengewinde auf, in der ein Halterohr 12 mit einem durchgehenden Längsschlitz 121 angeordnet ist. An dem gegenüberliegenden Endbereich des Halterohrs 12 ist ein Drückergehäuse 100 aufgeschraubt, welches an der Außenseite an einem Deckel des Spülkastens 1 anliegt und diesen in der Verschlußposition haltert. In dem Drükkergehäuse 100 ist ein erster großflächiger Drücker 10 vorgesehen, in dem ein zweiter kleinflächiger Drücker 11 angeordnet ist. Der erste Drücker 10 ist mit einem Gestänge 42 mit der Aushebevorrichtung 4 verbunden. Der zweite Drücker 11 ist über ein koaxial zum Gestänge 42 in dem Halterohr 12 angeordneten Druckrohr 61 verbunden, welches am unteren Endbereich einen oberhalb des Überlaufrohrs 3 angeordneten Ringflansch 611 trägt, an dem ein von einer Rückstellfeder 620 gedrückter Stößel 62 anliegt. Der Ringflansch 611 ist hierbei über einen Radialansatz 610 mit dem Druckrohr 61 verbunden, wie es insbesondere aus Figur 34 zu entnehmen ist. Das Druckrohr 61 wird hierbei axial in das Halterohr 12 eingeführt, wobei der Radialansatz 610 durch den Längsschlitz 121 hindurchgreift, während der Ringflansch 611 im übrigen einen freien Ringraum 612 aufweist, durch den das Halterohr 12 hindurchgreift.
Die Aushebevorrichtung 4 trägt im Bereich der Muffe 41 koaxial ein Führungsstück 45, welches axial verschieblich in einem Tragkörper 47 der Aushebevorrichtung 4 angeordnet ist und von einer Rückstellfeder 451 gegen die untere Stirnseite des Gestänges 42 gedrückt ist. An dem Tragkörper 47 der Aushebevorrichtung 4 sind zwei gegenüberliegende zweiarmige Hebel 46 angeordnet, welcher jeweils einerseits über eine pleuelartige Lasche 450 mit dem Führungsstück 45 verbunden ist, während die andere Seite des Hebels 46 mit einem Fortsatz einer Klaue 40 verbunden ist. Die beiden Klauen 40 sind darüber hinaus über ringförmig ausgebildete Federelemente elastisch miteinander verbunden. Die Klauen 40 sind hierbei im Bereich eines umlaufenden Innenwulstes 30 des Überlaufrohrs 3 angeordnet. Außerdem ist im unteren Bereich der Aushebevorrichtung 4 eine Tellerscheibe 43 am Tragkörper 47 ausgebildet, mit der ein Hochsteigen des Spülwassers in dem Überlaufrohr 3 weitgehend verhindert wird.
An dem Verschlußglied 31 des Überlaufrohrs 3 ist radial und parallel zur Mittelachse eine Rastnase 32 ausgebildet, die mit einer Rastvorrichtung 5 zusammenwirkt. Die Rastvorrichtung 5 ist dabei von einer auf dem Kragen 21 angeordneten Bodenplatte 51 mit einer Führungsbuchse 510 und einer einen Außenmantel bildenden Kappe 63 begrenzt, wobei in dem hierin gebildeten Ringraum ein erster Schwimmer 50 angeordnet ist. Der Schwimmer 50 ist halbkreisringförmig ausgebildet und trägt am Rand im Bereich der Rastnase 32 zwei gegenüberliegende Lagerzapfen 502, mit denen er von auf der Bodenplatte 51 angeordneten Lagern 511 verschwenkbar aufgenommen ist. Am Schwimmer 50 ist im Bereich der Rastnase 32 eine Klinke 500 ausgebildet. Außerdem weist der Schwimmer 50 an den Endbereichen des Kreisringstücks jeweils einen Anschlag 501 auf. Darüber hinaus ist in der Bodenplatte 51 eine Öffnung 512 ausgebildet, durch die die Rastnase 32 in die Rastvorrichtung 5 einführbar ist. Im Bereich der Bodenplatte 51 ist außerdem an der Kappe 63 ein Auslaßschlitz 632 ausgebildet, mit dem mit Hilfe eines Drehschiebers (in der Zeichnung nicht dargestellt) die Entleerungsgeschwindigkeit des zwischen der Kappe 63 und der Bodenplatte 51 gesammelten Wassers einstellbar ist.
In the embodiment shown in the drawing, the outlet fitting is arranged in a cistern 1 shown only schematically and in part, the water inlet means being not shown. In the bottom area an outlet opening is formed, in which a bottom valve 2 is arranged sealed in a known manner. At the bottom of the valve 2 formed outlet 20, the flushing line is connected (not shown in the drawing). Inside the cistern 1, the bottom valve 2 is formed with an enlarged diameter collar 21, in the side wall water inlet slots 210 are arranged.
Coaxially to the bottom valve 2, an overflow pipe 3 is arranged, which carries at the lower end a ringflanschartig formed closure member 31 to which a sealing ring 310 is attached by means of a support ring 33, such that in the lowered position the overflow pipe 3 shuts off the outflow into the outlet port 20 ,
Coaxially to the overflow pipe 3, a lifting device 4 is arranged substantially in the interior of the overflow pipe 3. In the lower area in this case the lifting device 4 is held concentrically with a neck in the connecting piece 20. On the opposite side, the lifting device 4 has a sleeve 41 with internal thread, in which a holding tube 12 is arranged with a continuous longitudinal slot 121. At the opposite end portion of the holding tube 12, a pusher housing 100 is screwed, which rests on the outside of a lid of the cistern 1 and this holds in the closed position. In the Drükkergehäuse 100, a first large-size pusher 10 is provided, in which a second small-area pusher 11 is arranged. The first pusher 10 is connected to a linkage 42 with the lifting device 4. The second pusher 11 is connected via a coaxially to the linkage 42 in the holding tube 12 arranged pressure tube 61, which carries at the lower end an above the overflow tube 3 arranged annular flange 611, against which a pressed by a return spring 620 ram 62. The annular flange 611 is in this case connected via a radial extension 610 with the pressure tube 61, as can be seen in particular from Figure 34. The pressure tube 61 is in this case inserted axially into the holding tube 12, the radial extension 610 passing through the longitudinal slot 121, while the annular flange 611 otherwise has a free annular space 612 through which the holding tube 12 engages.
The lifting device 4 carries in the region of the sleeve 41 coaxially a guide piece 45 which is arranged axially displaceably in a support body 47 of the lifting device 4 and is pressed by a return spring 451 against the lower end face of the rod 42. On the support body 47 of the lifting device 4 two opposing two-armed lever 46 are arranged, which is connected on the one hand via a connecting rod-like tab 450 with the guide piece 45, while the other side of the lever 46 is connected to an extension of a claw 40. The two jaws 40 are also elastically connected to each other via annular spring elements. The claws 40 are in this case arranged in the region of a circumferential inner bead 30 of the overflow pipe 3. In addition, in the lower region of the lifting device 4, a dish washer 43 is formed on the support body 47, with which a rising of the rinse water in the overflow pipe 3 is largely prevented.
On the closure member 31 of the overflow pipe 3, a latching nose 32 is formed radially and parallel to the central axis, which cooperates with a latching device 5. The latching device 5 is bounded by a arranged on the collar 21 bottom plate 51 with a guide bushing 510 and an outer shell forming cap 63, wherein in the annulus formed herein, a first float 50 is arranged. The float 50 is semicircular in shape and carries at the edge in the region of the latching lug 32 two opposing bearing journals 502, with which it is received by 5 arranged on the bottom plate 51 bearings 511 pivotally. On the float 50, a pawl 500 is formed in the region of the latching nose 32. In addition, the float 50 at the end portions of the Kreisringstücks each have a stopper 501 on. In addition, an opening 512 is formed in the bottom plate 51, through which the locking lug 32 is inserted into the locking device 5. In the region of the bottom plate 51, an outlet slot 632 is also formed on the cap 63, with the help of a rotary valve (not shown in the drawing), the emptying speed of the collected between the cap 63 and the bottom plate 51 water is adjustable.

Zur Drehsicherung sind an dem Außenmantel des Überlaufrohrs 3 radial vorstehende Rippen 35 angeformt, die in entsprechende Ausnehmungen 513 an der Führungsbuchse 510 einfassen und somit eine drehfeste Axialbewegung des Überlaufrohrs 3 gewährleisten.To prevent rotation are on the outer jacket of the overflow pipe 3 radially projecting ribs 35 formed in corresponding recesses 513 on the guide bush 510 border and thus a rotationally fixed axial movement ensure the overflow pipe 3.

In einem Ansatz 630 der Kappe 63 ist eine Teilspülvorrichtung 6 angeordnet. Hierbei ist ein zweiter Schwimmer 60 halbkreisringförmig ausgebildet und mit einer Schnappvorrichtung 600 auf einer Stange 65 höhenverstellbar mit einer Brücke 64 verbunden. Der Schwimmer 60 umgreift das Überlaufrohr 3 zur Hälfte auf der dem Schwimmer 50 gegenüberliegenden Seite. An der der Stange 65 gegenüberliegenden Seite trägt die Brücke 64 einen seitlich vorstehenden Lagerzapfen 640, an dem ein Steuerhebel 66 mit einem Augenlager 662 verschwenkbar angelagert ist. Das Augenlager 662 weist hierbei einen Radialschlitz 6620 auf, so daß der Steuerhebel 66 radial schnappend auf den Lagerzapfen 640 aufgesprengt werden kann. Am gegenüberliegenden Endbereich ist der Steuerhebel 66 mit einem von dem Überlaufrohr 3 wegzeigenden Steuerzapfen 660 versehen, der in eine in dem Ansatz 630 ausgebildete Steuernut 631 einfaßt. Die Steuernut 631 weist eine Ruheposition 6310 für den Steuerhebel 66 auf, in der die Teilspülvorrichtung 6 außer Betrieb ist. Die Steuernut 631 weist unterschiedliche Tiefen auf, die mit Hilfe eines im Steuerhebel 66 vorgesehenen Federelements, das in Form einer ersten geraden der Steuernut 631 zugekehrten Blattfeder 663 und einer zweiten dem Überlaufrohr 3 zugekehrten Blattfeder 664 von etwa kreisbogenförmiger Ausbildung gebildet ist, von dem Steuerzapfen 660 ertastet werden. Außerdem weist der Steuerhebel 66 im mittleren Bereich eine Schrägfläche 661, die mit einer Stirnseite des Stößels 62 zusammenwirkt. Der Stößel 62 ist einerseits im Ansatz 630 und andererseits in einer Führungsbohrung 340 eines auf dem Überlaufrohr 3 kraftschlüssig gehaltenen Führungsring 34 gelagert.In a projection 630 of the cap 63 is a partial flushing device 6 arranged. Here is a second float 60 semi-circular ring-shaped and with a Snap device 600 height adjustable on a rod 65 connected to a bridge 64. The swimmer 60 surrounds the overflow pipe 3 in half on the Float 50 opposite side. At the bar 65 opposite side carries the bridge 64 a laterally projecting bearing pin 640, on which a Control lever 66 with an eye bearing 662 pivoted is attached. The eye bearing 662 here has a Radial slot 6620, so that the control lever 66 radially snapping on the bearing pin 640 are blown up can. At the opposite end is the Control lever 66 with a pointing away from the overflow pipe 3 Control pin 660 provided in a in the Approach 630 formed control groove 631 borders. The Control groove 631 has a rest position 6310 for the Control lever 66, in which the Teilspülvorrichtung. 6 is out of order. The control groove 631 has different Depths, with the help of one in the control lever 66 provided spring element, in the form of a first straight the control groove 631 facing the leaf spring 663rd and a second overflow pipe 3 facing the leaf spring 664 formed by approximately circular arc-shaped training is to be felt by the control pin 660. Furthermore the control lever 66 is in the middle area an inclined surface 661, which with an end face of the Tappet 62 cooperates. The plunger 62 is on the one hand in the approach 630 and on the other hand in a guide bore 340 held on the overflow pipe 3 frictionally Guide ring 34 stored.

Die vorstehend beschriebene Ablaufarmatur hat folgende Funktionsweise:
In Fig. 1 der Zeichnung befindet sich die Auslaufarmatur in Ruheposition, wobei das Bodenventil 2 geschlossen und der Spülkasten 1 maximal mit Spülwasser 13 gefüllt ist.
Wird nun vom Benutzer der erste Drücker 10 in das Drükkergehäuse 100 eingedrückt, wie es in Figur 2 und 3 der Zeichnung dargestellt ist, so erfolgen folgende Aktionen:
Das Gestänge 42 schiebt das Führungsstück 45 in den Tragkörper 47 der Aushebevorrichtung 4 ein, wodurch die Schiebebewegung auf die beiden Stellhebel 46 von den Laschen 450 übertragen wird. Die Hebel 46 kehren die Bewegungsrichtung um und ziehen hierdurch mit den Klauen 40, die an dem Innenwulst 30 des Überlaufrohrs 3 anliegen, das Überlaufrohr 3 vom Bodenventil 2 hoch, wonach die Rastnase 32 durch die Öffnung 512 hinter die Klinke 500 des Schwimmers 50 greift und das Überlaufrohr 3 in dieser Position verrastet, so daß das Bodenventil 2 in Offenstellung verharrt und das Spülwasser 13 aus dem Spülkasten 1 über den Auslaßstutzen 20 abgegeben wird. Der Schwimmer 50 ist hierbei durch die einseitige Lagerung durch den Auftrieb in eine Schräglage gebracht und hält die Rastnase 32 in dieser Position mit der Klinke 500 fest. Sobald das Niveau des Spülwassers 13 im Spülkasten 1 den von der Bodenplatte 51 und den Mantelbereich der Kappe 63 gebildeten Ringraum erreicht hat, strömt das in diesem Ringraum vorhandene Wasser im wesentlichen über den Auslaßschlitz 632 ab. Sobald das Wasser in dem Ringraum genügend weit abgesunken ist, bewirkt die Schwerkraft, daß der Schwimmer 50 in eine waagerechte Lage zurückkehrt und hierbei die Klinke 500 die Rastnase 32 freigibt, so daß nunmehr das Überlaufrohr 3 mit dem Verschlußglied 31 auf das Bodenventil 2 zurückfällt und den Auslaßstutzen 20 absperrt. Nunmehr wird von einer Wasserzulaufsteuerung der Spülkasten 1 wieder mit Spülwasser 13 aufgefüllt und ist danach wieder einsatzbereit.
Bei der Betätigung des Drückers 10 verharrte der Drükker 11 in seiner Ruheposition 6310. Der in Fig. 3 gezeigte Steuerhebel 66 wurde somit von dem Stößel 62 nicht aus seiner Ruheposition 6310 ausgelenkt, so daß die Teilspülvorrichtung bei dieser Betätigung außer Betrieb geblieben ist.
The drain fitting described above has the following operation:
In Fig. 1 of the drawing, the outlet fitting is in the rest position, the bottom valve 2 is closed and the cistern 1 is filled with rinse water 13 maximum.
Now, if the user presses the first pusher 10 in the Drükkergehäuse 100, as shown in Figures 2 and 3 of the drawing, the following actions take place:
The linkage 42 pushes the guide piece 45 in the support body 47 of the lifting device 4, whereby the sliding movement is transmitted to the two levers 46 of the tabs 450. The levers 46 reverse the direction of movement and thereby pull with the jaws 40, which rest against the inner bead 30 of the overflow pipe 3, the overflow pipe 3 from the bottom valve 2 high, after which the locking lug 32 engages through the opening 512 behind the pawl 500 of the float 50 and the overflow pipe 3 locked in this position, so that the bottom valve 2 remains in the open position and the rinse water 13 is discharged from the cistern 1 via the outlet port 20. The float 50 is brought here by the one-sided storage by the buoyancy in an inclined position and holds the locking lug 32 in this position with the pawl 500 fixed. As soon as the level of the rinsing water 13 in the cistern 1 has reached the annular space formed by the base plate 51 and the jacket area of the cap 63, the water present in this annular space flows essentially via the outlet slot 632. As soon as the water in the annulus has dropped sufficiently, gravity causes the float 50 to return to a horizontal position, thereby releasing the pawl 500, the latching nose 32, so that now the overflow tube 3 with the closure member 31 falls back onto the bottom valve 2 and the outlet port 20 shuts off. Now, the cistern 1 is refilled with rinse water 13 from a water supply control and is then ready for use again.
Upon actuation of the pusher 10, the pusher 11 remained in its rest position 6310. The control lever 66 shown in Fig. 3 was thus not deflected by the plunger 62 from its rest position 6310, so that the Teilspülvorrichtung has remained out of operation in this operation.

Durch die Einstellung eines Austrittsquerschnitts mit einem in der Zeichnung nicht dargestellten Drehschieber am Auslaßschlitz 632 kann der Zeitpunkt für die Lösung der Rastnase 32 aus der Rastvorrichtung 5 variabel eingestellt werden, wodurch das im Spülkasten verbleibende Restwasser bestimmbar ist.By setting an outlet cross-section with a rotary valve, not shown in the drawing at the outlet slot 632 may be the time for the solution the detent 32 from the locking device 5 variably adjusted which leaves what remains in the cistern Residual water is determined.

Werden dagegen der Drücker 10 und der Drücker 11 gleichzeitig betätigt, wie es in Figur 4 und 5 der Zeichnung dargestellt ist, so werden folgende Vorgänge in der Ablaufarmatur ausgelöst:
Von dem Drücker 10 wird über das Gestänge 42 die Aushebevorrichtung 4 in der vorstehend beschriebenen Weise betätigt, so daß das Überlaufrohr 3 mit dem Verschlußglied 31 von dem Bodenventil 2 abgehoben und die Rastnase 32 in der Rastvorrichtung 5 am Schwimmer 50 fixiert wird. Parallel wird über den zweiten Drücker 11 das Druckrohr 61 mit dem Ringflansch 611 axial in Richtung auf das Bodenventil 2 verschoben, so daß der Stößel 62 entgegen der Kraft der Rückstellfeder 620 mit seinem Stirnbereich an der Schrägfläche 661 zur Anlage gelangt und den Steuerhebel 66 mit seinem Steuerzapfen 660 aus der Ruheposition 6310 in der Steuernut 631 seitlich auslenkt, wie es insbesondere aus Figur 5 zu entnehmen ist. Der Steuerzapfen 660 wird hierbei über die beiden Blattfedern 663,664 axial verschoben und gelangt in den Bereich E bis F, wie es aus Figur 25 und 26 insbesondere zu entnehmen ist. Hiermit ist die Teilspülvorrichtung aktiviert, wobei der Steuerhebel 66 über die Brücke 64 und die Stange 65 mit dem zweiten Schwimmer 60 verbunden ist, so daß nunmehr das Niveau der Brücke 64 von dem Schwimmer 60 bestimmt ist.
Wie es insbesondere aus Fig. 6 und 7 ersichtlich ist, gelangen, nachdem der Benutzer die Drücker 10 und 11 losgelassen hat, diese wieder in ihre Ausgangsposition, während das Spülwasser über den Auslaßstutzen 20 abfließt. Hierbei sinkt das Niveau des Spülwassers im Spülkasten 1, so daß der zweite Schwimmer 60 mit der Brücke 64 und dem mit dem Steuerzapfen 660 in der Steuernut 631 geführten Steuerhebel 66 entsprechend abwärts sinkt. Der Steuerzapfen 660 gelangt dadurch von dem Bereich F in den Bereich A, wobei ein Axialsprung verhindert, daß der Steuerzapfen 660 in den Bereich F zurückgeführt werden kann (vgl. Fig. 25 und 26). Sobald das Niveau im Spülkasten 1 so weit abgesunken ist, daß die Brücke 64 an den Anschlägen 501 des ersten Schwimmers 50 zur Anlage gelangt, wird dieser durch das Gewicht des zweiten Schwimmers 60, der Stange 65, der Brücke 64 und des Stellhebels 66 aus seiner Schräglage, entgegen der Auftriebskraft, in eine waagerechte Position zurückgeführt, so daß nunmehr die Rastnase 32 von der Klinke 500 freigegeben wird und das Überlaufrohr 3 mit dem Verschlußglied 31 auf das Bodenventil 2 zurückfällt und den Auslaßstutzen 20 absperrt und somit den Teilspülvorgang beendet. Nunmehr wird von der in der Zeichnung nicht dargestellten Auffüllvorrichtung das Spülwasser 13 in dem Spülkasten 1 wieder aufgefüllt, so daß nunmehr von dem Schwimmer über die Stange 65 die Brücke 64 mit dem Steuerhebel 66 entsprechend aufsteigt, wobei der Steuerzapfen 660 von dem Bereich A in den Bereich B, in den Bereich C,D,E,, nämlich der Ruheposition 6310, zurückgeführt wird. Die Ablaufarmatur befindet sich somit wiederum in der gleichen Ausgangssituation wie sie in Figur 1 der Zeichnung dargestellt ist und ist bereit für einen erneuten Voll- oder Teilspülvorgang.
Die Spülwassermenge, die mit einem Teilspülvorgang abgegeben werden soll, kann durch eine Verstellung des zweiten Schwimmers 60 mit der Schnappvorrichtung 600 auf der Stange 65 in einem weiten Bereich eingestellt werden.
Zur günstigen Betätigung der Ablaufarmatur sollte der zweite Drücker 11 mit einer relativ kleinen Betätigungsfläche versehen werden, so daß bei der Einleitung des Spülvorgangs entweder beide Drücker 10,11 oder nur der erste Drücker 10 betätigt wird.
If, on the other hand, the pusher 10 and the pusher 11 are actuated at the same time, as shown in FIGS. 4 and 5 of the drawing, the following processes are triggered in the discharge fitting:
From the pusher 10, the lifting device 4 is actuated via the linkage 42 in the manner described above, so that the overflow pipe 3 is lifted with the closure member 31 of the bottom valve 2 and the latching lug 32 is fixed in the latching device 5 on the float 50. In parallel, the pressure tube 61 with the annular flange 611 is axially displaced via the second pusher 11 in the direction of the bottom valve 2, so that the plunger 62 comes against the force of the return spring 620 with its face on the inclined surface 661 to the plant and the control lever 66 with his Control pin 660 deflects laterally out of the rest position 6310 in the control groove 631, as can be seen in particular from FIG. The control pin 660 is axially displaced over the two leaf springs 663, 644 and reaches the region E to F, as can be seen in particular from FIGS. 25 and 26. Hereby, the partial flushing device is activated, wherein the control lever 66 is connected via the bridge 64 and the rod 65 with the second float 60, so that now the level of the bridge 64 is determined by the float 60.
As can be seen in particular from FIGS. 6 and 7, after the user has released the pushers 10 and 11, they return to their starting position, while the rinsing water flows out via the outlet connection 20. In this case, the level of the rinsing water in the cistern 1 decreases, so that the second float 60 decreases correspondingly downward with the bridge 64 and the control lever 66 guided in the control groove 631 with the control pin 660. The control pin 660 thereby passes from the region F into the region A, wherein an axial jump prevents the control pin 660 can be returned to the area F (see Fig. 25 and 26). Once the level in the cistern 1 has dropped so far that the bridge 64 comes to the stops 501 of the first float 50 to the plant, this is by the weight of the second float 60, the rod 65, the bridge 64 and the actuating lever 66 of his Oblique position, contrary to the buoyancy, returned to a horizontal position, so that now the locking lug 32 is released from the pawl 500 and the overflow pipe 3 falls back with the closure member 31 on the bottom valve 2 and the outlet port 20 shuts off and thus ends the Teilspülvorgang. Now, the flushing water 13 is refilled in the cistern 1 from the filling device, not shown in the drawing, so that now rises from the float on the rod 65, the bridge 64 with the control lever 66 accordingly, the control pin 660 of the area A in the Area B, in the area C, D, E, namely, the rest position 6310, is returned. The drain fitting is thus again in the same starting situation as shown in Figure 1 of the drawing and is ready for a renewed full or Teilspülvorgang.
The amount of flushing water to be discharged with a partial flushing operation can be adjusted by adjusting the second float 60 with the snap device 600 on the rod 65 in a wide range.
For favorable operation of the drain fitting, the second pusher 11 should be provided with a relatively small actuating surface, so that when triggering the rinsing process either both pushers 10,11 or only the first pusher 10 is actuated.

Nach der Einleitung eines Vollspülvorgangs mit dem Drücker 10 kann außerdem dieser Spülvorgang durch eine nachträgliche Betätigung des Drückers 11 in einen Teilspülvorgang umgewandelt werden.After the initiation of a full rinse with the Pusher 10 may also this rinsing by a subsequent actuation of the pusher 11 in a Teilspülvorgang being transformed.
