Die Figur 1 zeigt ein Ablaufventil 30, das ein rohrförmiges Gehäuse 1 aufweist, an dem ein Gewindestutzen 26 angeformt ist, der in eine Oeffnung 48 eines Spülkastenbodens 25 eingesetzt und mit einer Mutter 27 dicht an diesem festgeklemmt ist. In eine obere kreisrunde Oeffnung 43 (Figur 4) des Gehäuses 1 ist eine Einheit 10 eingesetzt, an der eine horizontale Trennwand 2 mit einer mittigen Oeffnung 33 angeformt ist. In die Oeffnung 33 ist von unten ein als Ueberlaufrohr ausgebildetes Schliessorgan 4 eingesetzt, das an seinem unteren Ende 5 einen Ventilteller 6 besitzt, der ein Dichtungskörper bildet und mit dem Ventilsitz 44 zusammenarbeitet. Am oberen Ende 7 des Schliessorgans 4 ist eine Lasche 34 angeformt, in die ein Hebel 35 einer hier nicht näher bezeichneten Betätigungsvorrichtung eingreift. Mit dieser Vorrichtung kann das Schliessorgan 4 angehoben und dadurch das Ventil geöffnet werden. Im Spülkasten vorhandenes Spülwasser 45 kann bei geöffnetem Ventil durch seitliche Fenster 28 des Gehäuses 1 und eine Oeffnung 46 des Stutzens 26 in eine hier nicht gezeigte WC-Schüssel abfliessen.Figure 1 shows a drain valve 30, which is a tubular Has housing 1, on which a threaded connector 26 is formed which is inserted into an opening 48 of a cistern floor 25 and clamped tightly to it with a nut 27 is. In an upper circular opening 43 (Figure 4) of the housing 1, a unit 10 is used, on which a horizontal partition 2 is formed with a central opening 33 is. In the opening 33 is a from below Overflow pipe formed closing member 4 used has at its lower end 5 a valve plate 6 which forms a sealing body and cooperates with the valve seat 44. At the upper end 7 of the locking member 4 is one Shaped tab 34, in which a lever 35 is not one here engages specified actuator. With this device, the closing member 4 can be raised and thereby opening the valve. Existing in the cistern Flushing water 45 can be opened when the valve is open Window 28 of the housing 1 and an opening 46 of the Drain nozzle 26 into a toilet bowl, not shown here.

Das Gehäuse 1 und die Einheit 10 sind mit einem separat hergestellten kreisförmigen Deckel 12 lösbar miteinander verbunden. Dazu ist am Deckel 12 unterseitig ein Rastring 36 angeformt, an dem zwei gegenüberliegende Rastzähne 37 der Einheit 10 von unten eingerastet sind. Diese Rastzähne 37 sind gemäss den Figuren 2 und 3 an einem oberen Rand 47 einer becherförmigen Wandung 11 angeformt. Ausnehmungen 38 seitlich, neben und unterhalb der Zähne 37 ermöglichen eine radiale Auslenkung beim Einrasten dieser Zähne. Die Einheit 10 ist am Ring 36 drehbar gelagert, wobei die Zähne 37 am Rastring 36 in Umfangsrichtung entlanggleiten können.The housing 1 and the unit 10 are separate with one manufactured circular lid 12 releasably together connected. For this purpose there is a locking ring on the underside of the cover 12 36 integrally formed on which two opposing locking teeth 37 the unit 10 are engaged from below. These ratchet teeth 37 are according to FIGS. 2 and 3 on an upper edge 47 molded on a cup-shaped wall 11. Recesses 38 laterally, next to and below the teeth 37 allow one radial deflection when these teeth snap into place. The unit 10 is rotatably mounted on the ring 36, the teeth 37 on Can lock ring 36 slide in the circumferential direction.

Der Deckel 12 besitzt zudem zwei gegenüberliegende Laschen 24, die sich gemäss Figur 8 am Rand des Deckels vertikal nach oben und nach unten erstrecken. Die Laschen 24 sind jeweils seitlich einer Oeffnung 49 des Deckels 12 angeformt. Der obere Bereich 47 der Laschen 24 bildet jeweils einen Griff, an dem die Laschen 24 in Richtung der Pfeile 50 elastisch verschwenkbar sind. Die an einem unteren Bereich 23 der Laschen 24 angeformten Rastzähne 51 werden hierbei nach aussen in Richtung der Pfeile 52 verschwenkt. Der Eingriff der Zähne 51 an einem weiteren umlaufenden Rastring 53 des Gehäuses 1 kann damit gelöst und die Einheit 10 aus dem Gehäuse 1 herausgehoben oder auf diesem beliebig gedreht werden. Beim Aufsetzen des Deckels 12 auf das Gehäuse 1 rasten die Laschen 24 unter elastischer Auslenkung selbsttätig am Rastring 53 ein. Der Zusammenbau des Gehäuses 1 mit der Einheit 10 und dem Deckel 12 kann sehr einfach automatisch durch Zusammenstecken erfolgen. Eine Demontage ist ohne Werkzeuge sehr schnell und wiederholt möglich.The lid 12 also has two opposite tabs 24, which is vertical according to Figure 8 on the edge of the lid extend up and down. The tabs 24 are each formed on the side of an opening 49 of the cover 12. The upper region 47 of the tabs 24 forms in each case a handle on which the tabs 24 in the direction of the arrows 50 are elastically pivotable. The one at the bottom 23 of the tabs 24 are formed locking teeth 51 here pivoted outwards in the direction of arrows 52. The engagement of the teeth 51 on another rotating one Locking ring 53 of the housing 1 can thus be released and the unit 10 lifted out of the housing 1 or on it as desired to be turned around. When putting the lid 12 on the housing 1 latches the tabs 24 with elastic deflection automatically on the locking ring 53. The assembly of the Housing 1 with the unit 10 and the lid 12 can be very simply done automatically by plugging them together. A Disassembly is very quick and repeated without tools possible.

Das rohrförmige Schliessorgan 4 ist in der Oeffnung 8 des Deckels 12 durch vorstehende Führungsrippen 40 längsverschieblich geführt. Seitliche Schlitze 39 erlauben den Durchtritt von Luft vom Spülkasteninnenraum in einen ringförmigen Raum 59 der Einheit 10, sobald das Niveau 54 des Spülwassers 45 während eines Spülvorgangs unterhalb dieser Schlitze 39 abgesunken ist.The tubular closing member 4 is in the opening 8 of the Cover 12 is longitudinally displaceable by projecting guide ribs 40 guided. Lateral slots 39 allow the Passage of air from the interior of the cistern into an annular one Room 59 of unit 10 as soon as level 54 of the Flushing water 45 during a flushing process below this Slots 39 has dropped.

Damit zur Unterbrechung der Spülung die in die Kammer 59 eingedrungene Luft unterhalb die Trennwand 2 gelangen kann, sind gemäss Figur 11 über- und unterhalb der Trennwand 2 jeweils in der Wandung 11 sowie in einer unten anschliessenden rohrförmigen Wandung 55 jeweils wenigstens ein Durchbruch 20 bzw. 21 angeordnet. Die Luft kann vom Durchbruch 20 über den Durchbruch 21 unter die Trennwand 2 in eine Kammer 9 gelangen, wenn die Einheit 10 in eine Position gedreht ist, in der die Durchbrüche 20 und 21 im Bereich einer länglichen, sich vertikal erstreckenden Vertiefung 15 der Innenseite des Gehäuses 1 angeordnet ist. Die Vertiefung ist in Figur 5 gezeigt. In Figur 11 ist der Weg der Luft in die Kammer 9 mit dem Pfeil 56 angedeutet. Der Durchgang durch die Durchbrüche 20 und 21 sowie die Vertiefung 15 sind so dimensioniert, dass das Wasser im ringförmigen Raum 53 vergleichsweise langsam abfliesst und das Ventil erst dann schliesst, wenn Luft in die Kammer 9 eintritt und der Spülkasten im wesentlichen vollständig geleert ist. Wie ersichtlich erstreckt sich die Vertiefung 15 in vertikaler Richtung des Gehäuses 1 und ist überall etwa gleich tief und breit. Die Durchbrüche 20 und 21 bzw. die Trennwand 2 können somit auf beliebiger Höhe der Vertiefung 15 angeordnet sein, ohne dadurch die Sinkgeschwindigkeit des Schliessorgans 4 zu beeinflussen.So that to interrupt the flushing into the chamber 59 penetrated air can get below the partition 2, are above and below the partition 2 according to FIG each in the wall 11 and in a subsequent one below tubular wall 55 at least in each case an opening 20 or 21 is arranged. The air can from Opening 20 through opening 21 under partition 2 get into a chamber 9 when the unit 10 is in position is rotated in the openings 20 and 21 in the area an elongated, vertically extending recess 15 the inside of the housing 1 is arranged. The Indentation is shown in Figure 5. In Figure 11 is the way the air in the chamber 9 indicated by the arrow 56. Of the Passage through the openings 20 and 21 and the recess 15 are dimensioned so that the water in the ring Room 53 flows out comparatively slowly and that The valve only closes when air enters the chamber 9 and the cistern is essentially completely emptied is. As can be seen, the depression 15 extends in the vertical direction of the housing 1 and is approximately everywhere equally deep and wide. The breakthroughs 20 and 21 and the Partition 2 can thus at any height of the recess 15 may be arranged without reducing the rate of descent of the locking device 4.

Soll das Ablaufventil 30 zur Auslösung einer Teilspülung vor einer vollständigen Entleerung des Spülkastens schliessen, so wird gemäss Figur 10 die Einheit 10 in eine Drehstellung gedreht, in der ein Längsschlitz 22 der Einheit 10 mit einem Durchbruch 13 des Gehäuses 1 in Deckung ist. In dieser Drehstellung der Einheit 10 kann gemäss Figur 10 Luft in Richtung des Pfeiles 58 von der Aussenseite 57 des Gehäuses 1 durch den Durchbruch 13 und den Schlitz 22 ungehindert und direkt in die Kammer 9 gelangen. Der Durchtritt ist wesentlich breiter als beim Durchtritt in Richtung des Pfeiles 56, so dass die Kammer 9 sehr schnell mit Luft gefüllt wird, sobald die Oberfläche des Spülwassers 45 gemäss Figur 10 den Durchbruch 13 erreicht hat. Das Schliessorgan 4 schliesst das Ablaufventil dann vor der vollständigen Entleerung des Spülkastens. Bei der vollständigen Spülung wird beispielsweise eine gesamte Spülwassermenge von 9 Liter und im anderen Fall lediglich eine Teilmenge von 6 Liter zur Spülung benutzt. Der Luftdurchtritt in Richtung des Pfeiles 58 ist auch dann gewährleistet, wenn der Schlitz 22 höher angeordnet ist.Should the drain valve 30 trigger a partial flush before the cistern is completely emptied close, the unit 10 according to FIG Rotated position rotated in the longitudinal slot 22 of the unit 10 with an opening 13 of the housing 1 in cover is. In this rotational position of the unit 10, according to FIG 10 air in the direction of arrow 58 from the outside 57 of the housing 1 through the opening 13 and the slot 22 go unhindered and directly into the chamber 9. Of the Passage is much wider than when passing in Direction of arrow 56, so the chamber 9 very quickly filled with air once the surface of the rinse water 45 has reached breakthrough 13 according to FIG. The Closing element 4 then closes the drain valve in front of the complete emptying of the cistern. With the full Flushing is, for example, a total amount of flushing water of 9 liters and otherwise only a subset of 6 liters used for rinsing. The passage of air in the direction of arrow 58 is also guaranteed if the slot 22 is located higher.

Die Einheit 10 kann bezüglich des Gehäuses 1 in die gewünschte Drehstellung gedreht werden, indem das Schliessorgan 4 an seinem oberen Ende 7 angehoben wird, bis ein an einer oberen Wandung 29 (Figur 1) des Schwimmers 3 angeordneter Vorsprung 31 einen Vorsprung 32 an der Unterseite der Trennwand 2 aufnimmt und anschliessend das Schliessorgan 4 um seine Längsachse gedreht wird. Die Einheit 10 wird damit mitgenommen und in gleichem Sinn gedreht. Das Schliessorgan 4 wird dazu an seinem oberen Ende 7 entsprechend angehoben und gedreht. Die Verstellung ist damit sehr einfach und besonders bei schmalen und hohen Spülkästen, beispielsweise bei Unterputzspülkästen sehr bedienungsfreundlich, da nicht tief in den Spülkasten gegriffen werden muss.The unit 10 can with respect to the housing 1 in the desired Rotation position can be turned by the closing device 4 is raised at its upper end 7 until one on an upper wall 29 (Figure 1) of the float 3 arranged Projection 31 a projection 32 on the underside of the Partition 2 takes up and then the closing member 4th is rotated about its longitudinal axis. The unit 10 is thus taken along and shot in the same sense. The closing organ 4 is raised accordingly at its upper end 7 and turned. The adjustment is very simple and special for narrow and tall cisterns, for example for concealed cisterns very easy to use because not must be reached deep into the cistern.

Die genannten beiden Drehpositionen sind durch Anschlagnokken 17 am unteren Rand der Einheit 10 und durch Auflagenokken 16 an der Innenseite 14 des Gehäuses 1 bestimmt. Zwischen zwei Anschlagnocken 17 ist in der Aussenseite 18 der Einheit 10 jeweils eine umlaufende Vertiefung 19 eingearbeitet, in welche ein Vorsprung 42 (Figuren 6 und 7) eingreift, der gemäss Figur 7 über einem Auflagenocken 16 angeordnet ist. Seitlich neben jedem Anschlagnocken 17 sind jeweils Vertiefungen 41 eingearbeitet, in welche jeweils ein Vorsprung 42 einrastbar ist. Die Einheit 10 kann somit in jeder der beiden Drehpositionen verrastet werden. Die Auflagenocken 16 und die Aufschlagnocken 17 können jeweils einfach als auch mehrfach vorhanden sein. Dies gilt auch für die durch die Vorsprünge 42 und Vertiefungen 41 gebildete Rastvorrichtung.'Die Anschlagnocken 17 sind gemäss den Figuren 2 und 3 keilförmig ausgebildet, und gleiten an den schmalen, vorspringenden Nocken 16 seitlich ab, falls zufälligerweise beim Einsetzen der Einheit 10 in das Gehäuse 1 die Nocken 17 auf die Auflagenocken 16 auftreffen sollten. Die Einheit 10 kann somit auch in dieser Hinsicht automatisch in das Gehäuse 1 eingesetzt werden. Bei einer Handmontage ist ein Sichtkontakt zu den Nocken 17 und 16 nicht notwendig.The above two rotational positions are due to stop cams 17 at the lower edge of the unit 10 and by Aufokokken 16 determined on the inside 14 of the housing 1. Between two stop cams 17 is in the outside 18 of the Unit 10 each incorporated a circumferential recess 19, into which a projection 42 (FIGS. 6 and 7) engages, arranged according to Figure 7 over a support cam 16 is. Laterally next to each stop cam 17 wells 41 each, incorporated into each a projection 42 can be snapped into place. The unit 10 can thus can be locked in each of the two rotational positions. The Support cams 16 and the impact cams 17 can each be single or multiple. this is also valid for those formed by the protrusions 42 and depressions 41 Locking device.'The stop cams 17 are according to the Figures 2 and 3 wedge-shaped, and slide on the narrow, projecting cams 16 laterally, if by chance when inserting the unit 10 into the housing 1 the cams 17 should strike the support cams 16. The unit 10 can thus also automatically in this regard be used in the housing 1. At a Manual assembly is visual contact with cams 17 and 16 unnecessary.
