Abstract

A hydraulic drive for a hydraulic consumer alternately pressurized in opposite directions during operation is disclosed. The hydraulic drive includes (i) first and second hydraulic power outputs, (ii) a hydraulic machine driven by an electric machine, said hydraulic drive comprising a first hydraulic working output which is connected to the first drive output via a first hydraulic line, and comprising a second hydraulic working output connected to the second drive output via a second hydraulic line, (iii) an infeed device which is configured to feed hydraulic fluid from a tank into the first and/or the second line in a pressure-dependent manner by way of an infeed line, and (iv) a outfeed device which is configured to selectively open or close a hydraulic connection between the first hydraulic line and a hydraulic outfeed line which is hydraulically connected to the tank in a controllable manner and a hydraulic connection between the second hydraulic line and the hydraulic outfeed line to be selectively opened or closed in a controllable manner.
