Abstract
A turbo-compressor for an internal combustion engine includes a centripetal turbine driven by the engine exhaust gases, the turbine containing a housing designed to receive a free-rotating wheel, the housing possessing an exhaust gas inlet intended to be connected to the exhaust manifold of the engine and extending perpendicular to the axis of rotation of the wheel, an intake pipe extended by an incurved passage machined inside the housing opening on the periphery of the wheel, so as to direct the exhaust gases radially toward the center of the wheel, in order to rotate the latter, a second interior passage collecting the exhaust gases at the outlet of the wheel and a discharge pipe whose outlet is intended to be connected to the exhaust line of the engine, the second passage being incurved. The axis of the exhaust gas outlet extends perpendicular to the axis of rotation of the wheel. The axis of the exhaust gas outlet and the axis of the exhaust gas inlet are appreciably on the same transverse plane relative to the axis ol the wheel.
