초록

A turbomachine having an impeller rotating within a casing of the machine and groove passages are formed in a wall of the casing between an upstream portion and a downstream portion of the impeller and high pressure fluid is injected into the groove passages for increasing the stall margin without lowering the peak efficiency of the machine and prevents generation of a positive slope in a head-capacity curve.

청구항

[ What is claimed is:] [1.] A turbomachine having an impeller rotating within a casing of said machine and circumferential groove passages formed in a wall of said casing between an upstream portion and a downstream portion of said impeller, characterized in that said machine comprises a high pressure fluid injecting means for injecting high pressure fluid having a velocity component opposite to a direction component of said impeller rotation into said groove passages formed in said casing.
