Abstract (en)
[origin: EP2628862A2] The mobile working machine (10) has multiple hydraulic consumers (11,13) and another hydraulic consumer, where one of the former consumers has a traveling drive and an operating drive of the mobile working machine. A pressure storage (50) is provided for storing the hydraulic fluid stands under pressure, where the pressure storage stands in fluidic connection with the former consumers such that the hydraulic fluid flows back from the former consumers, in which the pressure storage runs, but not vice versa. An independent claim is included for a hydraulic drive system with a return pressure balance.
