Patent ID: 8307649

Claim:
An arrangement of a two stage turbocharger system for an internal combustion engine comprising an intake manifold and an exhaust manifold, comprising: a low-pressure turbocharger comprising a low-pressure turbine and a low-pressure compressor; a high-pressure turbocharger comprising a high-pressure turbine and a high-pressure compressor; a bypass duct in flow communication with an outlet of the low-pressure compressor and with an inlet of the high-pressure compressor and with an outlet of the high-pressure compressor and with an inlet of the intake manifold, the bypass duct comprising a bypass valve for opening and closing the bypass duct; a common housing, wherein the bypass valve and the high-pressure compressor are each integrated within the common housing; and a pipe, wherein the outlet of the low-pressure compressor is coupled to a first end of the pipe by a first free-floating interface and the inlet of the high-pressure compressor is coupled to a second end of the pipe by a second free floating interface, wherein the first free-floating interface is orthogonal to the second free-floating interface.
