The invention relates to a hydraulic drive, comprising a hydraulic cylinder (), divided into a first operating pressure chamber () and a second operating pressure chamber (), by an operating piston (). The hydraulic drive further comprises a closed hydraulic circuit (), with a first hydraulic pump (), connected to the first operating pressure chamber () via a first working line (), by means of a first connector () and to the second operating pressure chamber () via a second working line (), by means of a second connector (). In addition, an open hydraulic circuit () is provided, with a second hydraulic pump (), connected to the first operating pressure chamber (), by means of a third connector (). A fourth connector () on the second hydraulic pump () is connected to a hydraulic reservoir element ().

Hydraulic drive

The invention relates to an axial piston machine having a first group of pistons () for delivering into a first hydraulic circuit and a second group of pistons () for delivering into a second hydraulic circuit. The pistons () of the first group and the pistons () of the second group are supported on a common slanted swash plate (') and the slanted swash plate (&#x2032;) can be slanted to a first swivel axis () in order to regulate a first delivery volume of the first group of pistons () in the first hydraulic circuit () and to a second swivel axis () in order to regulate a second delivery volume of the second group of pistons () in the second hydraulic circuit.
