Abstract

Es wird eine Kolbenpumpe mit mehreren Kolben (6, 7) vorgeschlagen, die über einen Exzenter (4) angetrieben werden, wobei der Exzenter (4) auf die Kolben (6, 7) lediglich eine Druckkraft ausübt. Erfindungsgemäß sind die Kolben (6, 7) über ein Element (8), das im Betrieb der Kolbenpumpe zumindest Zugkräfte aufnehmen kann, miteinander verbunden.
