Abstract
A multistage exhaust turbocharger is easily mountable in a narrow engine compartment of a vehicle by simplifying its construction and reducing its bulk. The multistage exhaust turbocharger has a high-pressure stage turbocharger and a low-pressure stage turbocharger. A cover of the high-pressure stage turbocharger has a compressor inlet passage, a bypass inlet passage, a switching aperture between the passages to be opened and closed by a valve body of the compressor bypass valve device, and a bypass outlet pipe part connecting to the bypass inlet passage to introduce bypass air passed through the aperture opened by the bypass valve to the compressor bypass channel which is to be connected to the bypass outlet pipe part.
