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. It is a piston pump with a plurality of pistons (6, 7) proposed, which are driven by an eccentric (4), wherein the eccentric (4) on the piston (6, 7) only exerts a compressive force. According to the invention, the pistons (6, 7) are connected to one another via an element (8) which can absorb at least tensile forces during operation of the piston pump.
