Abstract: A high-pressure plunger pump includes a plunger assembly having a working chamber and a plunger positioned in the working chamber that is movable in an axial direction, as we as first and second control valves connected to a valve housing having at least one high-pressure line and at least one low-pressure line, which are respectively connected to the working chamber by first and second control valves. The valve housing having a high-pressure connection that opens into the high-pressure line. The first and second control valves are actuable by a control unit in such a way that a fluid, which is fed via the high-pressure connection of the valve housing and is under high pressure, is fed to the working chamber and is dischargeable via a low-pressure connection of the suction valve after driving the plunger. The plunger is coupled to a generator via a driveshaft.
