Vapors in the fuel tank of a vehicle are collected in a carbon canister. An ejector or aspirator is used to purge the carbon canister in a pressure-charged engine in which a positive pressure exists in the intake. A compact ejector includes a substantially planar flange and a venturi tube coupled to the flange with a central axis of the venturi tube substantially parallel to the flange. By manufacturing the ejector in two pieces, dimensions within the ejector: throat, converging section, and diverging section, is more accurate than prior art manufacturing techniques thereby providing better flow characteristics throughout the boost range. By forming one of the two pieces of the ejector integrally with the air intake component in which it is coupled, decreases part count and the number of manufacturing processes.
