摘要

The rotary valve for controlling the flow of bulk materials in a pneumatic conveyor system has two partial rotors (12, 13), each of which has an open sector (16, 17). These are out of register with each other, so that one opens below the inlet pipe (3) as the other closes when the rotors are rotating.
