Abstract (en)
The pump (1) has a set of pistons (6, 7) driven by an eccentric cam (4), where the eccentric cam exerts a compressive force on the pistons. The pistons are connected with each other by a single-piece u-shaped bent pin element i.e. clip (8), that absorbs tractive forces in the operation of the piston pump. The pistons execute a reciprocating movement by the eccentric cam, where the pistons are displaceable to a starting position during the movement by the pin element. The pin element is connected with each piston by a detachable plug connection.
Abstract (de)
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.
