Abstract
A drive, which permits a lowering in the feed pressure provided by the feed pump and, at the same time, effects a supply to the displacement unit of the drive which meets the demand with regard to pressure and delivery volume. This is achieved in that the displacement unit () is supplied with hydraulic energy by an electro-hydraulic supply unit () wherein the supply unit () comprises a hydraulic reservoir () and a non-return valve () and is connected to the feed pressure limiting valve (), which is implemented as an electrically adjustable pressure limiting valve, wherein the hydraulic reservoir () is also connected to an electro-hydraulic pressure sensor (), which outputs the electric signal thereof to an electric auxiliary controller (), and wherein the electric auxiliary controller () drives the feed pressure limiting valve (). These hydraulic drives are used for example, in self-propelled working machines.
