Abstract (en)
[origin: US2016327050A1] A diaphragm rotatably covers an impeller around an axis. A diaphragm has a suction flow channel configured to supply a gas toward an inlet of an impeller, a diffuser flow channel through which the gas discharged from the impeller outward in a radial direction flows, and a communication section configured to bring the suction flow channel and the diffuser flow channel in constant communication with each other.
