ABSTRACT:
A pneumatic transport system in which a continuous overhead rail extends through a plurality of transport stations. Transport tubes are arranged along the rail for high-speed travel of a vehicle which is suspended therefrom. Between the transport tubes, the vehicle rests upon driven rollers which propel the vehicle into the tubes and receive the vehicle after it leaves the tubes. In the stretches provided with these rollers, the rail approaches the rollers so that the vehicle rests upon the rollers and is only guided laterally by the rail. Within the tubes themselves, however, the vehicle is suspended from the rail generally out of contact with the walls of the tubes and is displaced through the latter by a pressure differential generated by suction devices.
