Die Erfindung betrifft einen Spucknapf mit durch einen Tritthebel in Tätigkeit zu setzender Spülpumpe. Die Erfindung besteht darin, daß die als Balgpumpe ausgebildete Spül-S pumpe in einem besonderen Gehäuse eingekapselt ist, dessen Boden gleichzeitig den Pumpenboden bildet. Durch diese Anordnung wird seitlich und über der Pumpe ein vollständig abgeschlossener, dem SpülwasserThe invention relates to a spittoon to be set into action by a step lever Irrigation pump. The invention consists in the fact that the flushing S, which is designed as a bellows pump pump is encapsulated in a special housing, the bottom of which is also the Pump bottom forms. This arrangement creates a completely closed off, the flushing water, on the side and above the pump

ίο nicht zugänglicher, wasserleerer Raum geschaffen, in den die mit dem außerhalb des Spucknapfes liegenden Tritthebel in Verbindung stehenden Zugstangen zum Bewegen des Balges durch hohle, die Pumpe mit dem Spucknapf boden verbindende Schrauben geführt sind. Da um diese Schrauben besondere Dichtungsscheiben gelegt sind, so kann das Spülwasser wohl zu der im Boden der Pumpe befindlichen Saugstelle, nicht aber zu den für die Hohlschrauben vorgesehenen Durchlochungen der beiden . Böden gelangen; ein Heraussickern des Spülwassers aus dem Spucknapf ist also ausgeschlossen. . Außerdem ist noch das die Spülöffnung im Speitrichter überdeckende Deckplättchen für die Verteilerklappe derart ausgebildet, daß das unter ihm hervortretende Wasser in Wellenbewegung den Trichter umkreist.ίο inaccessible, water-free space created, into the pull rods for moving, which are connected to the step lever located outside the spittoon of the bellows through hollow screws connecting the pump to the base of the spittoon are. Since special sealing washers are placed around these screws, this can be done Rinse water to the suction point in the bottom of the pump, but not to the perforations of the two provided for the banjo bolts. Soils get; a This means that the rinsing water cannot seep out of the spittoon. . Also is nor the cover plate for the distributor flap that covers the flushing opening in the spout funnel designed in such a way that the water protruding from under it in wave motion Funnel circled.

Auf der Zeichnung ist der Erfindungsgegenstand in Fig. 1 im lotrechten Schnitt, in Fig. 2 in Draufsicht mit teilweise entfernt gedachtem Trichter, in Fig. 3 in lotrechtem, zum Schnitt nach Fig. 1 um go ° gedrehtem Teilschnitt durch die Spülpumpe dargestellt.In the drawing, the subject of the invention is in FIG. 1 in vertical section, in FIG. 2 in plan view with partially removed funnel, in Fig. 3 in perpendicular to the Section according to FIG. 1 partial section rotated by go ° represented by the flushing pump.

Die Spülpumpe im Innern des Spucknapfes ist derart angeordnet, daß neben ihr im Behälter α ein für den Durchgang des Wassers mit Löchern versehener Sputumtopf b unterhalb des abnehmbaren Spültrichters c eingestellt werden kann. Der zylindrische Gummibalg β der Spülpumpe d ist an seinem oberen Ende in dem Doppelringe f der beweglichen Decke g, am unteren Ende in dem Doppelringe h des feststehenden Bodens i, der gleichzeitig den Boden des die Balgpumpe umgebenden Gehäuses, k bildet/eingespannt.The flushing pump inside the spittoon is arranged in such a way that next to it in the container α a sputum pot b provided with holes for the passage of water can be set below the removable flushing funnel c. The cylindrical rubber bellows β of the flushing pump d is clamped at its upper end in the double ring f of the movable ceiling g and at the lower end in the double ring h of the fixed base i, which at the same time forms the base of the housing surrounding the bellows pump, k.

Im Innern der Balgpumpe ist eine Schraubenfeder I angeordnet, die sich gegen den Boden und die Decke der Pumpe stützt und nach dem Zusammenpressen des Balges β stets den Saughub vollzieht. Der Boden i ist in der Mitte mit einer von einem Klappenventil m überdeckten Saugöffnung und seitlich unterhalb des Hohlraumes zwischen der Gehäusewand k und dem Balge e mit zwei Durchlochungen für die Hohlschrauben r versehen. In dem Doppelringe h ist ein Loch η vorgesehen, an welches die Druckleitung 0 anschließt, die in den Spültrichter c mündet und durch eine Gummiklappe p abgedeckt ist. So A helical spring I is arranged inside the bellows pump, which is supported against the floor and the ceiling of the pump and which always performs the suction stroke after the bellows β is compressed. The bottom i is provided in the middle with a suction opening covered by a flap valve m and laterally below the cavity between the housing wall k and the bellows e with two perforations for the banjo bolts r . A hole η is provided in the double ring h , to which the pressure line 0 connects, which opens into the flushing funnel c and is covered by a rubber flap p . So

Das Gehäuse k, dessen eine Wand an dem Behältermantel α anliegt und nach oben so weit verlängert ist, daß sie mit einer Umbördelung über den Rand des Behältermantels a The housing k, one wall of which rests against the container jacket α and is extended upward so far that it is flanged over the edge of the container jacket a

Claims

engages, whereby the flushing pump is given a secure position, remains with its bottom i from the bottom of the spittoon container so far away that the flushing water can easily flow to the suction opening. The housing base i of the flushing pump is supported by two washers q,. which, reaching around the banjo bolts r, at the same time form a seal for the perforations provided for the latter, so that the. Rinse water can neither pass up into the cavity between the wall k and the bellows e, nor down through the bottom of the spittoon. The two tie rods s go through the banjo bolts r, which are connected to the step lever t through the strip w and to the ceiling g of the flushing pump through the strip ν. The banjo bolts r. are head or flange screws with nuts screwed onto the external thread in order to fasten the housing and the pump to the spittoon container. . Instead of the nuts or next to them, the two front feet u can be screwed onto the thread. Above the rubber plate p covering the flushing opening in the spittoon funnel c, which has the purpose of sucking in air through the flushing opening in addition to sucking in water through the opening in the bottom i when the bellows e goes back after flushing. prevent a wave-shaped curved cover plate on the sides is arranged, as shown in the drawing to the right of FIG. Through this curvature of the cover plate x, to which the rubber plate p hugs, the tangentially exiting water is given a wave movement in both directions, which leads to a sharp collision of the water opposite the exit opening and thus a strong, expanding over the entire spout funnel Flush generated. So that when the flushing stops, the rubber plate p is easily detached from the cover plate χ, the latter has several incisions z that allow the air to quickly penetrate between the two plates. Godfather nt-A ν Proverbs:

1. Spittoon with a rinsing pump to be set into action by a step lever, characterized in that the rinsing pump (d) designed as a bellows pump is encapsulated in a special, water-free housing (k) , the bottom (i) of which simultaneously forms the pump bottom.

2. Spittoon according to claim i, characterized in that the housing (k) and the pump (d) on the spittoon base by hollow screws (r) which simultaneously serve as a guide to the tie rods connected to the foot lever (s) are attached and through sealing washers underneath

(q) must be kept at the distance from the container bottom necessary for the access of the rinsing water to the suction point provided in the bottom (i).

3. spittoon according to claim 1, characterized in that the cover plate (x) for das.die rinsing opening in the spit funnel covering rubber plate (p) is curved on both sides and provided with transverse incisions (z) .
