Abstract

Offenbart ist eine Hochdruckpumpe, insbesondere eine Radialkolbenpumpe mit zumindest einer Pumpeinheit, deren Kolben über einen Gleitschuh auf einem Exzenterring einer Antriebswelle abgestützt ist. Zur Lagesicherung des Exzenterrings ist in der Pumpeinheit ein Stützkolben angeordnet, der über eine Druckfeder gegen den Exzenterring vorgespannt ist. Die Axialbewegung des Stützkolbens wird über eine Haltescheibe auf den Kolben der Pumpeinheit übertragen. Der Stützkolben liegt dabei direkt oder über die Mitnahmescheibe oder auf sonstige Weise auf dem Gleitschuh auf.

Figure 00000001
What is disclosed is a high-pressure pump, in particular a radial piston pump with at least one pump unit, the piston of which is supported on a cam ring on an eccentric ring of a drive shaft. To secure the position of the eccentric ring, a support piston is arranged in the pump unit, which is biased against the eccentric ring via a compression spring. The axial movement of the support piston is transmitted to the piston of the pump unit via a retaining washer. The support piston rests directly or over the drive plate or in some other way on the slide shoe.
