Abstract

1347651 Circumferential-flow compressors SIEMENS AG 23 June 1972 [26 June 1971] 29667/72 Heading F1C In a compressor comprising a housing defining an annular duct for an impeller (not shown), the cross-section of the annular duct extending into the housing axially away from at at least one end free of the impeller to form a part-annular duct K which freely connects an inlet port S and an outlet port D, the housing is also provided, between the outlet port and the inlet port in the direction of travel of the impeller with an auxiliary outlet port A and an auxiliary inlet port E for communication with the entainment regions of the impeller. Gas that has been heated by compression and would otherwise be carried around in the interblade spaces of the impeller past the outlet and inlet ports D, S and subjected to further heating is expelled centrifugally through the port A and replaced by cooler gas drawn in through the port E. The gas expelled through the port A may be cooled in a cooler and then passed to the port E via a circulating pump.
