PORTED SHROUD / ANTI-SURGE COMPRESSOR HOUSING

The flow range of a turbo's compressor can be increased by allowing air to bleed from a ring of holes or a circular groove around the compressor at a point slightly downstream of the compressor inlet. The ported shroud is a performance enhancement that allows the compressor to operate at substantially lower flows. Allowing some air to escape at this location inhibits the onset of surge and widens the operating range.
