Принадлежит: Honeywell International Inc

An turbocharger includes a parallel twin-impeller compressor and separate inlets into the two impellers. A first or outboard impeller receives one stream of inlet air and a second or inboard impeller receives its own separate stream of inlet air by way of a generally annular inlet volute surrounding the inlet to the second impeller. Air is fed from the inlet volute radially inwardly through a feed passage to the inlet to the second impeller. A plurality of inlet guide vanes are located in the feed passage for the second impeller, the inlet guide vanes creating a swirling air stream into the second impeller. Introduction of swirl to the second impeller alters the flow distribution between the impellers and affects the stability of the overall stage.

A turbocharger compressor includes an inlet-adjustment mechanism operable to move between an open position and a closed position. The mechanism includes a plurality of movable blades disposed about the compressor air inlet and located between an upstream wall surface and a downstream wall surface of an annular space within the air inlet wall. The blades move radially inward from the annular space into the air inlet when the blades are in the closed position so as to form an orifice of reduced diameter relative to a nominal diameter of the inlet. Recirculation of air upstream through the mechanism is prevented by a downstream blade seal. When EGR is employed, an upstream blade seal is included, preventing oil-laden air from migrating into the mechanism. The blade seals can be of various types, including O-ring seals or labyrinth seals.
