Description

Abdichtung der seitlichen.Führungsenden bei Leistenkolben für Drehkolbenmaschinen Bei Drehkolbenmaschinen ist es für ein zuverlässiges Arbeiten erforderlich, daß die Kolben durch besondere Führungen zwangsläufig geführt werden, so daß die nötige Abdichtung zwischen Kolbentrommel und Zylinder bei allen vorkommenden Drehzahlen sicher bewirkt wird.Sealing of the lateral guide ends of in-line pistons for rotary piston machines In rotary piston machines, it is necessary for reliable operation that the pistons are inevitably guided by special guides, so that the necessary Sealing between the piston drum and cylinder at all speeds that occur sure is effected.

Zwangsläufige Führungen für die Kolben werden bei Drehkqlbenmaschinen vielfach angewendet, und ihre Anordnung bietet keine Schwierigkeiten, sofern die Durchmesser der Maschinen genügend groß gehalten werden können.Inevitable guides for the pistons are used in rotary table machines widely used, and their arrangement presents no difficulties, provided that the Machine diameter can be kept large enough.

Die größten Durchmesser sind durch die Drehzahlen der Maschinen gegeben, da die Drehzahl einer derartigen Maschine durch die Umfangsgeschwindigkeit des Läufers und der Kolben begrenzt ist. Um beispielsweise Drehzahlen von etwa 3ooo/min verwenden zu können, ergeben sich Zylinderdn@chmesser; die etwa 55 mm nicht überschreiten dürfen, da sonst Vakuum infolge der Fliehkraftwirkung'der Flüssigkeit in der Maschine entsteht.The largest diameters are given by the speed of the machines, because the speed of such a machine depends on the peripheral speed of the rotor and the piston is limited. For example, to use speeds of around 3ooo / min to be able to produce cylinder diameter; which do not exceed about 55 mm otherwise a vacuum due to the centrifugal force of the fluid in the machine arises.

Für die Ausführung von Maschinen mit derartig kleinen Durchmessern muß zu den an sich bekannten leistenartigen Kolben übergegangen werden. Leistenkolben nehmen in radialer Richtung den geringsten Platz in Anspruch, so daß sich noch eine genügend starke Welle unterbringen läßt, die größeren Querdrücken gewachsen ist. Die bekannten Maschinen mit leistenartigen Kolben ohne zwangsläufige Führung zum Zylinder sind nur für untergeordnete Zwecke verwendbar. Bei Anordnung von Führungen durch Verlängerung der Leistenkolben über die Trommelbreite hinaus sind bei derartigen Pumpen jedoch besondere Abdichtungen der Führungsschlitze der Trommel erforderlich.For the execution of machines with such small diameters must be switched to the known strip-like piston. Inguinal piston take up the least amount of space in the radial direction, so that there is still one can accommodate a sufficiently strong wave that can cope with greater transverse pressures. The known machines with strip-like pistons without inevitable guidance for Cylinders can only be used for subordinate purposes. When arranging guides by extending the bar piston beyond the width of the drum are such Pumps, however, require special seals for the guide slots in the drum.

Während bei zwangsläufig bewegten Kolben mit Flächenführungen in den Schlitzen der Trommel oder in besonderen Trommeleinsätzen die Kolbenführungsräume allseitig geschlossen sind- und künstlich für den nöti- ' gen Wechsel der Flüssigkeit in diesen Räumen gesorgt werden muß, ergeben sich jedoch bei der .Verlängerung der Leistenkolben zwecks zwangsläufiger Führung derselben Verbindungen mit den Arbeitsräumen, wie sie nachstehend näher geschildert sind. Die. Verhinderung dieser Verbindungen durch die Ausbildung der Leistenkolben selbst ist der Gegenstand der Erfindung. Erst hierdurch erhält die Maschine eine genügende Dichtheit, die sie für zuverlässige Förderungen und für höhere Drücke geeignet macht, so daß derartige Maschinen auch für regelbare Zwecke durch Verstellung der Exzentrizität Verwendung finden können.While with inevitably moving piston with surface guides in the Slots in the drum or, in special drum inserts, the piston guide spaces are closed on all sides and artificially for the necessary change of the liquid must be taken care of in these rooms, however, result in the .Extension of the Bar piston for the purpose of inevitable guidance of the same connections with the work areas, as described in more detail below. The. Prevention of these connections the subject of the invention is through the formation of the inguinal piston itself. Only in this way does the machine obtain sufficient tightness to make it reliable Promotions and makes it suitable for higher pressures, so that machines of this type also can be used for controllable purposes by adjusting the eccentricity.

Abb. i zeigt eine Drehkolbenmaschine mit den an sich bekannten Leistenkolben A, die jedoch zwecks zwangsläufiger.

Der :obere- KölberiAx und .der untere I<-grC ben-A= befinden sich_in den Zylinders; sie stehen mit dem Zylinder infolge der zwangsläufigen Führung dichtend in Berührung, desgleichen werden sie .durch den Druck gegen die eine Flanke der Trom- melschlitze gepreßt. Wie jedoch durch die Pfeile in Abb. i erkennbar ist; bestehen zwi- schen Trommel, Deckel und Leistenkolben Zwickel, durch die ein glattes Durchströmen - erfolgt. Durch die Erfindung wird der AbschluB dieser Zwickel in möglichst einfacher Weise erwirkt. Der AbschluB erfolgt durch' seif-. liches Abdecken dieser -Zwickel..
