摘要： A throttle assembly for a pressure control system in a vehicle includes at least one throttle valve. The at least one throttle valve defines an assembly cross-section of the throttle assembly, the assembly cross-section specifies a flow resistance acting on a pressure medium entering the throttle assembly, and the at least one throttle valve includes at least one controllable throttle valve configured to be controlled in accordance with an upstream pressure. The assembly cross-section of the throttle assembly is configured to be set, by control of the at least one controllable throttle valve, in such a way that an inlet volume flow of the pressure medium entering the throttle assembly can be limited to a limit volume flow in accordance with the upstream pressure, in order to set, in accordance with the upstream pressure, a power consumption of a pneumatic load in the pressure control system.

摘要： A method for operating a pressure control system in a vehicle includes controlling a flow-control valve in a charging line, which conveys a charging pressure medium, in dependence upon an admission pressure and/or upon an admission volume flow. The admission pressure and/or the admission volume flow characterizes a prevailing or currently to be expected loading of a pneumatic consumer of the pressure control system during the supply of the charging pressure medium with a charging volume flow and at a charging pressure into the pneumatic consumer. The method further includes adjusting a flow-control cross-section, which acts on the charging pressure medium as it flows through the flow-control valve, or adjusting an average flow-control cross-section so as to limit the charging volume flow to a limit volume flow. The method additionally includes outputting the volume-flow limited charging pressure medium to the pneumatic consumer.

摘要： A method for operating a pressure control system having a multistage compressor includes outputting, by the multistage compressor in order to fill a pressure medium store or pressure medium chambers of the pressure control system, a pressure medium compressed multiple times. Outputting the pressure medium compressed multiple times includes providing, by a first compression stage, a precompressed pressure medium and further compressing, by a second compression stage, the precompressed pressure medium to form a compressed pressure medium and then outputting the compressed pressure medium. Alternatively, outputting the pressure medium compressed multiple times includes providing a compression pressure medium, which is obtained from additional compression of an already compressed charge pressure medium from the pressure medium reservoir or the pressure medium chambers of the pressure control system, wherein the compression pressure medium is output without additional compression by the second compression stage.

摘要： A method for operating a pneumatic system having a compressed air supply system and an air spring system includes determining at least one deflection of at least one air spring of the pneumatic system. The air spring is configured to be connected to a gallery in a selectively gas-conveying manner via a valve. The method further includes determining at least one bellows volume of a spring bellows of the at least one air spring based on the at least one determined deflection, indicating a pneumatic surrogate model for the at least one bellows volume and/or for a pressure accumulator volume of a pressure accumulator of the pneumatic system based on a mass flow balance for a balance volume, and calculating, based on the pneumatic surrogate model, at least one pressure value of the at least one bellows volume, the pressure accumulator volume, and/or the balance volume.
