Abstract (en)
[origin: WO2023006270A1] The invention relates to a high-pressure plunger pump (2) which comprises: at least one plunger assembly (3) having a working chamber (31) and a plunger (32) that is positioned in the working chamber (31) so as to be movable back and forth in an axial direction; at least one first control valve (5) and at least one second control valve (6) which are connected to a valve housing (4) having at least one high-pressure line (41) and at least one low-pressure line (42), the high-pressure line (41) being connected to the working chamber (31) in a sealable manner by the first control valve (5) and the low-pressure line (42) being connected to the working chamber (31) in a sealable manner by the second control valve (6), the valve housing (4) having a high-pressure connection (43) that opens into the high-pressure line (41), the at least one first control valve (5) and the at least one second control valve (6) being actuable by means of a control unit (7) in such a way that a fluid, which is fed via the high-pressure connection (43) of the valve housing (4) and is under high pressure, is fed to the working chamber (31) and can be discharged via a low-pressure connection (61) of the at least one suction valve (6) after driving the plunger (32), the at least one plunger (32) being coupled to a generator (11) via a driveshaft.
