Conveyor arrangement for use in aircraft, has compressor to generate negative pressure in one container, if difference between pressure levels of two containers is not sufficient for transporting material

摘要

The arrangement comprises compressor (12) for generating negative pressure in container (7), if the difference between the pressure levels of two containers (3,7) is not sufficient for transporting the material from container (3) to another container (7). A throttle valve (15a) is connected to the compressor for controlling pressure difference. Independent claims are also included for the following: (1) method for adapting transportation behavior of material to be conveyed; and (2) use of arrangement for adapting transportation behavior of material to be conveyed.
