A method for operating a pressure control system having a multistage compressor. The method comprises providing a pressure medium compressed multiple times by the multistage compressor in order to fill a pressure medium reservoir or pressure medium chambers of the pressure control system, by performing (i) providing, by a first compression stage, a precompressed pressure medium and additionally compressing the precompressed pressure medium via a second compression stage, and/or (ii) introducing, into an intermediate volume between the first compression stage and the second compression stage of the multistage compressor, an already compressed charge pressure medium and compressing, by the second compression stage, the charge pressure medium again. An intermediate pressure of the precompressed pressure medium conveyed into the intermediate volume is limited by an overpressure valve interacting with the first compression stage. The overpressure valve is configured to open if the intermediate pressure exceeds a limit value.

A plug-in connection arrangement for a component includes a first portion having a first groove contour in a first annular groove arranged in the first portion, and a second portion having a second groove contour in a second annular groove arranged in the second portion. Via a resilient connection arrangement element arranged between the first portion and the second portion in the second annular groove, the first portion and the second portion can have a retention position relative to each other in a first position and which can be moved in an axial direction into a second position which is provided for operation. The second position is a sealing engagement position.

A compressed air supply unit for operating a pneumatic unit by means of a compressed air flow, in particular of an air suspension unit of a vehicle, comprises an air dryer arrangement in a main pneumatic line that pneumatically links a compressed air feed line from an air compressor and a compressed air connection to the pneumatic unit. A valve arrangement is pneumatically connected to the main pneumatic line for controlling the compressed air flow. The air dryer arrangement has a drying container having a container outer wall. A partition along a length of the drying container divides an internal space delimited by the container outer wall into first and second chambers delimited by the partition and the container outer wall. The partition adjoins the container outer wall along the length of the drying container, and the first and second chambers are adjacent to one another along that length.

A pressure medium supply arrangement for operating a pneumatic apparatus, comprises a pressure medium supply, a pressure medium connection, a vent connection and at least one pressure medium charging connection to the pneumatic apparatus, together with a suction line, a compressor line, a vent line and at least one pressure medium charging line. A charging apparatus is configured to simultaneously direct the pressurized pressure medium applied to the pressure medium charging connection, and the further pressure medium made available in the charging apparatus by the first compressor stage of a two-stage or multistage compressor, to the second compressor stage of the compressor.
