Definitions

  • volume flow and/or pressure of the central drive is divided between the working units.
  • the mutual influencing of the working units is thereby advantageously limited to a minimum, and it is always possible to control and/or limit the volume flow and/or the pressure of each working unit independently of other working units.
  • the at least one control valve is used to set normalized control commands and/or flow rates and/or volume flows of the working units independently of the system pressure and/or the load pressure of the at least one working unit, so that a desired volume flow, for example, can be advantageously set or regulated by a characteristic curve can. This results, for example, in a normalized flow rate or volumetric flow depending on a manipulated variable.
  • valve regulation and/or the valve control has knowledge about the hydraulic medium used, such as its viscosity. This means that depending on the medium, there is a corresponding pressure and a corresponding valve setting, which advantageously results in more precise pilot control.
