<p>A diverter for use in pneumatic conveyor duct systems, particularly for conveying loose particulate material, has a rotor and two ends, the ends being preferably axially spaced from each other. A least one switching conduit extends between the ends and is arranged to selectively communicate with different pairs of ports at the inlet and outlet side of the diverter. The area of ports includes resilient annular seals arranged to press against a counter-face of an end plate such that the seal is in engagement with the respective plate during the entire path of movement from one to another state of communication of the diverter. A cutout in the end plate is provided to facilitate inspection or exchange of the annular seals, the cutout being of a sufficient size to uncover the seal on appropriate turning of the rotor. A flat, supplementary seal can be used to assist the sealing function during the switching of the diverter. The rotor may be produced as an enclosed, pressurized unit which is particularly suitable for pressuretype pneumatic conveyor systems.</p> |
