Abstract: A centrifugal compressor has diffusers which convert a high velocity, low pressure stream of fluid which flows out of an impeller to a high-velocity high-pressure flow due to the action of a purality of stator blades disposed near the outer periphery of the impeller. In this compressor, the portion of the stator blade or of an auxiliary blade which is provided in the diffuser located on the side of a front shroud is disposed closer to the impeller than the portion thereof located on the side of a main shroud, and the leading edge of the stator blade is thus inclined from the portion thereof located on the side of the main shroud to the portion thereof located on the side of the front shroud. The configuration of the front edge of a stator blade or of an auxiliary blade which is provided in the diffuser is so improved as to restrict back flow which occurs on the side of the front shroud when the flow rate is small and to lower the minimum flow rate.

Abstract: The invention relates to a capacity control method for controlling the capacity of a multistage compressor in response to a flow rate signal by varying the openings of vanes at individual stages. The relationships of the openings of the vanes of the individual stages are made to vary in response to the flow rate signal from the multistage compressor. Thus, when the flow rate of the multistage compressor is far from the anti-surge capacity within the operable range thereof, it is possible to select vane opening relationships which provide the highest efficiency for the multistage compressor. When the flow rate of the multistage compressor drops to either a value near the anti-surge capacity or the inoperable range, on the other hand, it is possible to select vane opening relationships which provide an enlargement of the operating range of the multistage compressor, before the flow rate enters that inoperable range.
