Description

Pumpe mit umlaufendem, am Kolbenträger drehbar angeordnetem Scheibenkolben und sAraubengangförmigem Arbeitsraum, in den der Scheibenkolben eingreift. Die Erfindung betrifft Pumpen mit umlaufendem, am Kolbenträger drehbar angeordnetem Scheibenkolben und schraubengangförmigem Arbeitsraum, in den der Scheibenkolben eingreift.Pump with rotating disc piston rotatably arranged on the piston carrier and a helical working space in which the disc piston engages. The invention relates to pumps with a rotating disc piston rotatably arranged on the piston carrier and helical working space in which the disc piston engages.

Das Neue besteht darin, daß der Scheibenkolben aus einem Zahnrad gebildet wird, dessen Zähne in ein in das Gehäuse eingeschnittenes Gewinde eingreifen. Hierdurch wird der Vorteil erreicht, daß die Pumpe trotz leichterer Herstellungsmöglichkeit genauer ausgeführt werden kann als die bekannten Pumpen, so daß eine bessere Wirkung gewährleistet ist.The new thing is that the disc piston is made up of a gear whose teeth engage in a thread cut into the housing. Through this the advantage is achieved that the pump despite easier manufacturing possibility can be carried out more precisely than the known pumps, so that a better effect is guaranteed.

In der Zeichnung ist die Erfindung in einem Längs- und Querschnitt sowie einem wagerechten Schnitt durch die Steuerung dargestellt.In the drawing, the invention is in a longitudinal and cross-section as well as a horizontal section through the control.

An einer Welle b ist eine Kugel angedreht, die einen Einschnitt besitzt. In diesem Einschnitt ist ein Schneckenrad c auf einem Bolzen d drehbar so exzentrisch in der Kugel gelagert, daß die Zahnung des Rades einseitig übersteht. Diese überstehenden Zähne des Rades greifen in einen Schneckengang o ein, der in die der Welle entsprechende kugelrunde Ausbohrung des aus zwei Teilen al, & bestehenden Gehäuses eingeschnitten ist. Die Kugel der Welle füllt so den zwischen dem Schneckengang liegenden Raum aus und nimmt das Rad in sich auf. Bei der Drehung der Welle mit dem Rade wird das Rad mit seiner Zahnung durch den Schneckengang geführt, dreht sich dabei um seine eigene Achse und bewirkt so das Pumpen.A ball which has an incision is turned on a shaft b. In this incision, a worm wheel c is rotatable on a bolt d so eccentrically stored in the ball that the toothing of the wheel protrudes on one side. These protruding The teeth of the wheel mesh with a worm gear o that corresponds to that of the shaft spherical bore of the housing consisting of two parts al, & incised is. The ball of the shaft fills the space between the worm gear and takes in the wheel. When the shaft rotates with the wheel, this becomes The wheel is guided through the worm gear with its teeth and turns around his own axis and thus causes the pumping.

f ist ein Steuerkolben, der unter Vermittlung der Kanäle il, i2, h, l2, kl, k2 und der Federn gl, g2 bewirkt, daß trotz Umkehr der Drehrichtung der Pumpe ständig die Durchfiußrichtung von der Saugleitung l nach der Druckleitung m die gleiche bleibt. el und e' sind Überwurfmuttern zur Abdichtung der Treibwelle.f is a control piston which, through the mediation of channels il, i2, h, l2, kl, k2 and the springs gl, g2 has the effect that, despite the reversal of the direction of rotation, the Always pump the direction of flow from suction line 1 to pressure line m stays the same. el and e 'are union nuts for sealing the drive shaft.
