Bei Drehschiebern, namentlich bei solchen, deren zylindrische Gleitflächen exzentrisch zur Drehachse der Schieber verlaufen, so daß die Schieber sich beim Öffnen von ihrem Sitz abheben, tritt — besonders bei der Benutzung für stark absetzende Fließstoffe — der Nachteil auf, daß auf den Sitzflächen sich leicht Unreinigkeiten oder sonstige feste Stoffe ablagern und diese beim Schließen durch die ίο Schieber noch fester angedrückt werden. Die Erfindung, von der die Zeichnung ein Ausführungsbeispiel schematisch darstellt, hat einen Drehschieber zum Gegenstande, dessen Anordnung das Ansetzen von Ablagerungen auf den Sitzflächen dadurch verhütet, daß jeder sich bildende Ansatz sofort beim öffnen und Schließen des Schiebers beseitigt wird. Mit der Spindel g sind durch die Arme β zwei in den Punkten q drehbar an ihnen befestigte Schieber vereinigt. An die Wandflächen s des Gehäuses schließen sich keilförmige Verdickungen u an, die die vorderen Kanten w der Schieber, wenn diese in die Offenlage (punktiert) gelangen, durch das Auflaufen der Schieberkanten ν an die Gleitbahn s drücken, so daß die Kanten w bei der nächsten Schließbewegung diese Gleitbahn sauber schaben. Zweckmäßig ist es, die bei der Schließbewegung vorderen Kanten w der Schieber, wie gezeichnet, als Schneiden auszuführen, damit sie das Abschaben der Gleitflächen erfolgreicher verrichten. Pateht- Ansprüche:In rotary valves, especially those whose cylindrical sliding surfaces are eccentric to the axis of rotation of the slide, so that the slide lift off their seat when they are opened, the disadvantage occurs - especially when used for highly settling fluids - that the seat surfaces are easy to get on Deposit impurities or other solid substances and press them on even more firmly when closing by means of the ίο slides. The invention, of which the drawing shows an exemplary embodiment schematically, has a rotary slide valve for the object, the arrangement of which prevents the build-up of deposits on the seat surfaces in that any approach that forms is eliminated immediately when the slide is opened and closed. Two slides rotatably attached to them at points q are combined with the spindle g by the arms β. The wall surfaces s of the housing are joined by wedge-shaped thickenings u, which press the front edges w of the slider, when they come into the open position (dotted), against the slideway s due to the slider edges ν running up, so that the edges w at the next closing movement, scrape this slideway clean. It is useful to design the front edges w of the slider during the closing movement, as shown, as cutting edges so that they scrape off the sliding surfaces more successfully. Pateht claims: 1. Drehschieber, dadurch gekennzeichnet, daß im Innern des Gehäuses Steuerflächen (u) angeordnet sind, die die vorderen Kanten (w) der mit der Spindel (g) durch Gelenke (q) verbundenen Schieber bei der öffnungsbewegung an die Gleitflächen (s) drücken.1. Rotary slide, characterized in that inside the housing control surfaces (u) are arranged which press the front edges (w) of the slide connected to the spindle (g) by joints (q) against the sliding surfaces (s) during the opening movement . 2. Drehschieber nach Anspruch 1, dadurch gekennzeichnet, daß die vorderen Kanten (w) der Schieber zugeschärft sind, derart, daß der Schneidwinkel 45 ° oder weniger beträgt.2. Rotary slide valve according to claim 1, characterized in that the front edges (w) of the slide are sharpened in such a way that the cutting angle is 45 ° or less.
