Abstract

Die Erfindung betrifft eine Zahnringpumpe für flüssige Medien mit einem in einem Pumpengehäuse angeordneten, von einer Antriebswelle angetriebenen Laufradsatz.
Der Erfindung liegt die Aufgabe zugrunde, eine hochdynamische Zahnringpumpe zu entwickeln, die auch bei sehr kleiner Baugröße kostengünstig herstellbar ist. Die erfindungsgemäße Zahnringpumpe zeichnet sich insbesondere dadurch aus, dass im Pumpengehäuse (1) dem Laufradsatz (3) in axialer Richtung benachbart, ein in einer Ausgleichskolbenführung (12) des Pumpengehäuses (1) verdrehsicher geführter, stirnwandseitig am Außenrotor (5) des Laufradsatzes (3) anliegender Ausgleichskolben (13), mit einer in diesem Ausgleichskolben (13) befindlichen Lagerbohrung (14) in der die Antriebswelle (2) des Laufradsatzes (3) drehbar gelagert ist, angeordnet ist, wobei dem Laufradsatz (3) gegenüberliegend am Ausgleichskolben (13) ein in einer Steuerkolbenführung (15) geführter, über einen Steuerdruckraum (16) druckbeaufschlagbarer Steuerkolben (17) anliegt, und der Steuerdruckraum (16) über Druckkanäle (18) und Druckkammer (19) direkt mit der Druckniere (9) über den Druckanschlusskanal (11) verbundenen ist.

The invention relates to a gerotor pump for liquid media with a arranged in a pump housing, driven by a drive shaft wheelset.
The invention has for its object to develop a highly dynamic gear pump, which is inexpensive to produce even with very small size. The toothed ring pump according to the invention is characterized in particular by the fact that in the pump housing (1) adjacent to the wheelset (3) in the axial direction, one in a balancing piston guide (12) of the pump housing (1) guided against the front wall on the outer rotor (5) of the wheelset (3 ) is arranged with a compensating piston (13) located in this bearing bore (14) in which the drive shaft (2) of the wheelset (3) is rotatably mounted, wherein the wheelset (3) opposite to the balance piston (13 ) in a control piston guide (15) guided over a control pressure chamber (16) druckbeaufschlagbarer control piston (17) is applied, and the control pressure chamber (16) via pressure channels (18) and pressure chamber (19) directly to the pressure kidney (9) via the pressure port channel ( 11) is connected.
