Here, by pressing one not shown here Trigger button the first pull rod 4 with the first float 2 for small-volume flushing pulled up. That with the first float 2 and / or the first Drawbar 4 directly coupled overflow pipe 6 was in the position shown lifted upwards, with the sealing element 12 being lifted off the valve seat, so that flushing water can flow out of the cistern through the drain valve. The lower, second float is locked unchanged by means of bolt 30. As a result the outflow of the rinse water, the first float 2 sinks along with the overflow pipe 6 down until the first float 2 loses contact with the water and that Outlet valve is closed. The dimensioning is expediently carried out in such a way that in small-volume flushing about three to four liters of water from the cistern flow out.

Fig. 3 zeigt die Ablaufarmatur nach dem Auslösen der Großmengenspülung durch Hochziehen der zweiten Zugstange 32, insbesondere durch Drücken einer mit dieser gekoppelten Auslösetaste. Das Überlaufrohr 6 besitzt einen Mitnehmer 46, mit welchem eine Auflageelement 48 der zweiten Zugstange 32 korrespondiert. Das Auflageelement 48 ist unter dem Mitnehmer 46 angeordnet, so daß beim Hochziehen der zweiten Zugstange 32 eine Verbindung mit dem Mitnehmer 46 zustandekommt und folglich das Überlaufrohr mit dem Dichtelement 12 mit hochgezogen wird. Es sei festgehalten, daß zur Kleinmengenspülung der Mitnehmer 46 beim Hochheben des Überlaufrohres 6 außer Eingriff mit dem Koppelelement 48 bleibt, zumal der Mitnehmer in zweckmäßiger Weise oberhalb des Koppelelements 48 der zweiten Zugstange 32 angeordnet ist.Fig. 3 shows the drain fitting after triggering the large volume flush Pull up the second pull rod 32, in particular by pressing one with it coupled release button. The overflow pipe 6 has a driver 46 with which a support element 48 of the second tie rod 32 corresponds. The support element 48 is arranged under the driver 46, so that when pulling up the second Tie rod 32 a connection with the driver 46 comes about and consequently that Overflow pipe with the sealing element 12 is pulled up. It should be noted that for flushing small quantities of the drivers 46 when lifting the overflow pipe 6 except Engagement with the coupling element 48 remains, especially since the driver in an expedient manner is arranged above the coupling element 48 of the second tie rod 32.

Mit dem oberen Schwimmer 2 ist wenigstens ein Abstützelement verbunden, über welches nach dem Aufschwimmen des unteren Schwimmers 18 eine Verbindung mit dem oberen, ersten Schwimmer 2 hergestellt ist. Somit ist während der Großmengenspülung auch der untere zweite Schwimmer zur Abstützung des Überlaufrohres 6 im Einsatz, wodurch die Absinkgeschwindigkeit des Überlaufrohres 6 verzögert wird, und zwar derart, daß das im Spülkasten gespeicherte Wasser zumindest nährungsweise vollständig durch das Auslaufventil ausströmen kann. Mittels der Steuerbohrung 24 im einzigen, unteren Schwimmerbehälter 16 wird die Durchflußmenge und letztendlich die Ausströmzeit vorgegeben. Beim Entleeren drückt das Überlaufrohr 6 über dem Mitnehmer 46 und das Koppelelement 48 die zweite Zugstange 32 nach unten. Dabei gelangt die Sicherungsfläche 42 mit dem oberen Endteil 44 des Riegels 32 in Kontakt, welcher nach dem Absinken des unteren, zweiten Schwimmers 18 somit wieder zurückgedreht ist und gemäß Fig. 1 mit seinem unteren Ende 50 auf den unteren Schwimmer 18 aufliegt und diesen wieder arretiert.When lifting the second pull rod 32, the bolt 30 or its upper end part 44 pivoted by means of the guide surface 40 of the second tie rod such that its lower end part 50 disengages from second lower float 18, which is thus released and floats upwards in the manner shown. At least one support element is connected to the upper float 2 via which after the floating of the lower float 18 connects to the upper, first float 2 is made. Thus, during the large quantity flushing also the lower second float for supporting the overflow pipe 6 in Use, whereby the lowering speed of the overflow pipe 6 is delayed, and in such a way that the water stored in the cistern at least approximately can flow completely through the outlet valve. By means of the control bore 24 in single, lower float tank 16 is the flow rate and ultimately the Outflow time specified. When emptying, the overflow pipe 6 presses over the driver 46 and the coupling element 48 the second pull rod 32 down. Here comes the securing surface 42 is in contact with the upper end portion 44 of the latch 32 which after lowering of the lower, second float 18 thus turned back again 1 and with its lower end 50 onto the lower float 18 rests and locks it again.

In Fig. 4 ist perspektivisch der erste, obere Schwimmer 2 dargestellt, welcher bevorzugt als geschlossener, ringförmiger Hohlkörper ausgebildet ist. Im Zentrum enthält der Schwimmer 2 eine erste durchgehende Öffnung 52, durch welche das Überlaufrohr durchgeführt ist, wobei die zur Befestigung dienenden Rastelemente 10 am oberen Rand angeordnet sind. Radial außen enthält der erste Schwimmer 2 eine weitere durchgehende Öffnung 54 für die zweite Zugstange. Am unteren Ende des Schwimmers 2 sind die bereits erwähnten Abstützelemente 56, 57 angeordnet. Das untere Ende der zweiten Zugstange 32 kann in der angehobenen Stellung zwischen den beiden Abstützelementen 56, 57 durchgreifen. Nach dem Auslösen der Großmengenspülung gelangt der untere Schwimmer in Anlage mit den freien Enden der beiden Abstützelemente 56 mit der Folge, daß das Überlaufrohr nunmehr gemeinsam vom unteren und oberen Schwimmer abgestützt wird. 4 shows the first, upper float 2, which is preferred is designed as a closed, annular hollow body. At the center contains the Float 2 has a first through opening 52 through which the overflow pipe is carried out, the locking elements 10 used for fastening on the upper Edge are arranged. Radially outside, the first float 2 contains another continuous one Opening 54 for the second tie rod. At the bottom of the float 2 the support elements 56, 57 already mentioned are arranged. The lower end of the second tie rod 32 can be in the raised position between the two support elements 56, 57 reach through. After triggering the large volume flush the lower float is in contact with the free ends of the two support elements 56 with the result that the overflow pipe now together from the lower and upper Float is supported.
