  • Patent number: 6808237
    Abstract: The invention relates to a method for controlling the supply of a pressure medium on rail vehicles which are coupled together in a tractive link both mechanically and in order to enable the flow of said pressure medium, whereby said pressure medium is supplied by a main air container pipe which extends through all rail vehicles and which is fed with a pressure medium via a plurality of compressors individually mounted in each rail vehicle. The aim of the invention is to allow a balanced use of the compressors included in the tracture link. In order to achieve this, a changeable or fixed order of priority is defined for the compressors according to the total number of compressors in the tracture link, whereby the number of compressors activated depends on the order of priority necessary to meet the actual required amount of pressure medium.
