Method and apparatus for supplying compressed air according to the demand of vehicles, especially rail vehicles

摘要

The present invention relates to a method and apparatus for supplying compressed air according to the demand of a vehicle, in particular a rail vehicle, wherein at least the main air demand of the rail vehicle for the operation of the pneumatic brake system (3) is in the main tank air line (2). Additional compressed air for the operation of the auxiliary unit is produced by at least one electrically operated auxiliary air compressor (8), which is met by the connected main air compressor (1) and has a smaller feed output than the main air compressor, During the vehicle's parking mode, only at least one auxiliary air compressor (8) is used to generate compressed air if necessary, and the pantograph (5) operable with the pneumatic actuator (9) during the parking mode is powered by the compressed air. It remains in permanent contact with line 6.
