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.
