ABSTRACT:
A pneumatic transportation system for particulate material, such as powdered or granular materials, with a switching valve (7) for selection of different transport paths within the transportation system. The valve includes a turnable rotor (15) with a bore or a compartment (23), the inner part of which constitutes a blind space for forming an erosion-preventing cushion (26) of powder. An upstream conduit (6) is connected to the valve housing (14) opposite to the blind space of the compartment (23). In dependence on the position of the rotor (15), the compartment (23) or a channel (24) adjacent to this forms a connection to any one of several downstream conduits (20, 21) connected to the valve housing (14).
