Description

Drebkolbenpumpe mit sichelförmigem Arbeitsraum Gegenstand der Erfindung ist eine Drehkolbenpumpe mit sichelförmigem Arbeitsraum, bei der die Saugwirkung dadurch wesentlich erhöht ist, daß die rundlaufende Kolbentrommel so dicht als möglich am Zylindermantel anläuft, ohne daß Reibung stattfindet.Rotary piston pump with a sickle-shaped working space is the subject of the invention is a rotary lobe pump with a sickle-shaped working chamber with which the suction effect this is significantly increased that the rotating piston drum is as tight as possible runs against the cylinder jacket without friction taking place.

Die hierzu notwendige Genaupassung wird am besten und einfachsten erreicht, wenn Zylinder und Kolbentrommel gegeneinander verschoben und fein eingestellt werden können.The exact fit required for this is best and easiest achieved when the cylinder and piston barrel are shifted against each other and fine-tuned can be.

Solche Ausführungen sind bekannt. Sie erfordern jedoch für die Befestigung des Zylinders am Lagerflansch und für die Einstellung _ je besondere Schrauben.Such designs are known. However, they require for attachment of the cylinder on the bearing flange and for setting _ special screws.

Im Gegensatz hierzu ist bei der nachstehend beschriebenen Ausführung nur eine einzige Reihe von Schrauben notwendig, weil die besondere Anordnung dieser Schrauben sowohl Verschiebung des Zylinders gegen die Kolbentrommel gestattet als auch Anpressung an deren Lagerflansch bewirkt. Dabei ist die Anpressung und Abdichtung eine viel bessere als bei der gewöhnlichen Anschraubeart, weil zu der bekannten keilförmigen Wirkung des Schraubengewindes die weitere Keilwirkung einer kegelförmigen Schraubenspitze tritt und den Anpreßdruck um diese Keilwirkung vergrößert.In contrast, in the embodiment described below only a single row of screws necessary because of the special arrangement of these Screws both displacement of the cylinder against the piston barrel are permitted as also causes pressure on their bearing flange. Thereby the contact pressure and sealing a much better one than the usual screw-on type, because it is too well known wedge-shaped effect of the screw thread the further wedge effect of a conical The tip of the screw occurs and the contact pressure is increased by this wedge effect.

In der Zeichnung ist ein Ausführungsbeispiel dargestellt. Es zeigt Abb. 1 einen Querschnitt der Pumpe, Abb. 2 einen Längsschnitt durch einen Teil der Pumpe. In dem Lagerkörper a ist mit ihrer Achse b die .Kolbentrommel c drehbar gelagert. An dem denZylinderdeckeldarstellendenFlanschd des Lagers a sitzt der Zylinder e, welcher durch die Schrauben f, deren kegelförmige Spitzen g in entsprechend kegelförmige Vertiefungen 1a einseitig eingreifen, sowohl in radialer Richtung verstelle als auch an den Flansch d angepreßt werden kann. Es genügt auch, an Stelle der kegelförmigen Vertiefungen h den Flansch, wie bei 7' gezeigt, gegenüber der Anpreßfläche abzuschrägen.An exemplary embodiment is shown in the drawing. It shows Fig. 1 is a cross section of the pump, Fig. 2 is a longitudinal section through part of the Pump. In the bearing body a, the piston drum c is rotatably mounted with its axis b. The cylinder e is seated on the flange of the bearing a, which represents the cylinder cover. which by the screws f, whose conical tips g in correspondingly conical Depressions 1a engage on one side, both in the radial direction as can also be pressed against the flange d. It is also sufficient in place of the conical Depressions h bevel the flange, as shown at 7 ', with respect to the pressing surface.
