Abstract
A pneumatic transport system for transferring particulate material from a first pressurized container to a second container which is under a lower pressure, while successively reducing the pressure, comprising a number of parallel tubes (36), arranged in series, said tubes being joined together at their ends by means of transfer chambers (38) for transferring a gas/material stream from an upstream tube (36) to a downstream tube (36). The transfer chamber (38) are formed with tubular inlets and outlets (52, 56) opening out into a space (54) where a gas/material stream is transferred from the inlet (52) to the outlet (56). Between the inlet (52) and the outlet (56) there is a double-bent unsymmetrical surface, bulging towards the space (54), which conforms to the wall surfaces of the inlet (52) and the outlet (56).
