Abstract (en)

[origin: DE19740579A1] The hydraulic device has a setting pump (1) with valves between the device and the consumers, distributors and hydraulic components throttling the hydraulic fluid between the output of the setting pump and the inputs of the valves. The pressure (p9) at the input (9, 9') of the valves (7, 8) is taken to the pump regulator (16') as the regulating value. There may be a throttle between the output of the setting pump and the input of the valve to serve as a bypass.
