Abstract
A turbocharger includes a two-stage serial compressor having first and second impellers, with a crossover duct for leading air from the first impeller into the second impeller for further compression. The compressor housing also defines a bypass duct from the crossover duct to the air discharge duct from the compressor, and a bypass valve disposed in the bypass duct. Under certain operating conditions (such as high-flow, low-pressure-ratio conditions) the bypass valve can be opened to bypass the second impeller, such that the compressor behaves like a single-stage compressor. At other operating conditions, the bypass valve is closed so that the compressor provides two-stage compression for higher pressure ratios.
