Abstract: The disclosure relates to a working machine comprising an internal combustion engine and at least one secondary pneumatic or hydraulic working circuit, wherein during operation of the secondary working circuit, energy is recuperated and can be supplied to a pressure accumulator of the working machine for energy storage, characterised in that at least one auxiliary compressor is provided, which can be driven by the energy stored in the pressure accumulator, and an engine control unit is provided and configured to recognise a highly dynamic increase in the power demand on the internal combustion engine and, if necessary, to generate additional charge air by means of the auxiliary compressor, which is fed to the charge air path of the internal combustion engine in addition to the regular charge air flow of the internal combustion engine.

Abstract: This present disclosure relates to a device for recovering hydraulic energy in an implement with a mooring pump for operation as pump or as motor, with a high-pressure accumulator and with a throttle differential circuit for connecting the bottom side of a working cylinder with the rod side of the working cylinder of the implement, and to a corresponding implement.

Abstract: The present invention relates to a drive for an excavator with a number of individual drives, such as a slewing gear drive, a hoist drive, a bucket drive and an arm drive, wherein for the slewing gear drive two reversible adjusting units are provided, which are at least coupled with an energy accumulator.
