Abstract (en)
[origin: WO2014023744A1] The invention relates to a pumping device (1) comprising a drive device (2) for driving a feed element (3) of the pumping device (1) and a hydrostatic coupling (5), by means of which a torque transmission between the drive device (2) and the feed element (3) is controllable. It is essential for the invention here that a suction side (6) and a pressure side (7) of the hydrostatic coupling (5) are connected to one another by way of a coupling-fluid-carrying channel (8), wherein a valve device (9) is arranged in the coupling-fluid-carrying channel (8).
