Abstract
The subject compressor is of the centrifugal type having a rotatable impeller with hub and shroud sides and a diffuser surrounding the impeller, the diffuser having spaced side walls with vanes spaced around the impeller to provide passages for receiving fluid discharged from the impeller, the diffuser also having chambers formed on the hub and shroud sides and restricted openings along lines of static pressure in the diffuser passages establishing communication between the chambers and the diffuser passages near the inlet ends thereof whereby the pressures at such passage inlet ends will be equalized during the operation of the compressor and the tendency of the compressor to stall prematurely thereby reduced. Suitable communication between the chambers on the hub and shroud sides may be provided.
