Claims

[Scope of utility model registration request]

A fluid machine having a rotating impeller, wherein a suction chamber is connected to the upstream side of the impeller via a suction pipe for introducing working fluid, and the suction chamber is an axial extension of the impeller. In the flow control device having means for taking in the working fluid in an inward radial direction from a surface surrounding the impeller, a plurality of movable movable parts are provided inside the suction chamber in a substantially circumferential direction on the outer circumferential side of the axial extension line of the impeller. blades are disposed, and the movable blades are arranged radially such that a chord direction thereof typically indicates a right-angled ray with respect to the axial extension line, and the cord direction and a right-angled ray of the impeller. 1. A flow control device for a fluid machine, characterized in that the blade angle formed by the blade can be adjusted by a movable device.
