In the state shown in the figure, the hollow chamber (5) is communicated with a compressed air source (not shown), and compressed air whose pressure has been adjusted is supplied to the hollow chamber (5) via a pressure reducing valve (8) and a pressure gauge (7). This causes the seal cylinder (3) to move toward the rotor (2) (downward).
The rotor (2) is pressed against the concave arcuate surface (3) and is brought into close contact with the side discs (2C) (2C) and the vane plate (2D) of the rotor (2). By rotating, the rotor (2) completely closes the input port (IA) side of the casing (1) due to pressure contact between the seal cylinder (3), the side disk (2C), and the blade plate (2D). Therefore, even if the discharge port (IIEI side is connected to a transport pipe for transporting high-pressure, high-concentration air and used for supplying powder, the discharge port (IB) side The only thing that blows up the powder from the pocket is the residual pressure inside the pocket.
