Abstract

Beschrieben wird eine Vorrichtung zur Stabilisierung des Exzenterrings einer Radialkolbenpumpe mit mehreren, von einer gemeinsamen Exzenterwelle angetriebenen Kolben, die jeweils in einem im Pumpengehäuse fixierten Zylindereinsatz gleitbeweglich geführt sind und sich an abgeflachten Stützflächen des Exzenterrings abstützen, der drehbar auf einem Exzenter der Exzenterwelle gelagert ist. Um in allen Betriebszuständen der Pumpe und damit insbesondere in den Zuständen, in denen für die Pumpenkammern eine Unterversorgung vorliegt, zu verhindern, daß Dreh-/Kippschwingungen des Exzenterrings auftreten, ist eine hydraulische Verdrängerelementanordnung vorgesehen, mit der der Exzenterring in jeder Bewegungsphase der Pumpe durch aktive Druckbeaufschlagung der Verdrängerelementanordnung stabilisierbar ist. Mit dieser Verdrängerelementanordnung ist durch das Hinzufügen einer Schlitzsteuerungseinrichtung, eines Rückschlagventils, sowie eines Druckkanals und eines Saugkanals die Ausführung der Funktion einer Vorförderpumpe möglich.
