Claims

[Scope of utility model registration request]

An impeller that compresses gas in the radial direction, an inlet passage that allows gas to be sucked in along the axial direction between the impeller and the suction port of the wheel, and a suction that rotates within this passage to change the flow of the suction gas. a vane, a mechanism for rotating the suction vane between an open position and a closed position, a movable wall for changing the passage width of a differential user surrounding the outer circumferential side of the impeller as the suction vane rotates, and In a centrifugal gas compressor equipped with a piston for moving in conjunction with a vane, the piston has an inner circumferential groove formed at one end for rotating the suction vane, and the movable wall is integrally formed at the other end. The piston and the casing, which is formed in a substantially cylindrical shape provided in A centrifugal gas compression device characterized in that one fluid passage is controllably connected to a pressure fluid source and a space immediately in front of an impeller suction port via two valves arranged in parallel.
