<p>An exemplary port (180, 180′) includes a first port opening (182, 182′) positioned at a location downstream from a compressor wheel (140), a second port opening (184, 184′) positioned at a location adjacent to a blade (144) of the compressor wheel (140), and a third port opening (186, 186′) positioned at a location upstream from the compressor wheel (140) wherein the first port opening and the third port opening define a first flow path and wherein a second flow path extending from the second port opening meets the first flow path at a confluence (188, 188′). The first flow path optionally includes a venturi section, for example, wherein the confluence coincides at least in part with the venturi section. Other exemplary ports, compressor shrouds, systems and methods are also disclosed.</p> |
