In a piston pump () having a differential piston () positioned in a cylindrical housing () and translationally drivable, a first pressure chamber () of the differential piston () is connectable to a second pressure chamber () via a check valve () inserted into a connecting line (), and to a storage reservoir () via an inlet valve (). The differential piston () is provided with a dipping piston () attached to a piston rod (). In addition, a pass-through () of the piston rod () from the first pressure chamber () is closed fluid-tight by seals (), and a transport line () is positioned laterally offset from or concentric to the piston rod () in the vicinity of the pass-through () of the latter.
