Offenbart ist ein hydrostatischer Antrieb für ein Drehwerk einer stationären oder mobilen Arbeitsmaschine mit einem Speiseanschluss zum Ausgleich einer Leckage oder eines Differenzvolumenstroms.
Disclosed is a hydrostatic drive for a slewing gear of a stationary or mobile work machine, comprising a first hydraulic machine, a second hydraulic machine, an inflow channel fluidly connecting the first and second hydraulic machines, a return flow channel fluidly connecting the second hydraulic machine to a pressure medium sink, and a feed connection for compensating a leakage or a differential volume flow. The feed connection is selectively fluidly connected to whichever of the inflow channel and a return flow channel having higher pressure.
