  • Turbocharger apparatus having an exhaust gas sealing system for preventing gas leakage from the turbocharger apparatus
    Publication number: 20060213195
    Abstract: Turbocharger apparatus (1) comprising a housing (4), a compressor mounted for rotation in the housing (4), a turbine (40) mounted for rotation in the housing (4), a first inlet (39) for enabling air to be conducted to the compressor, an outlet (36) for enabling air from the compressor to be conducted to an engine, a second inlet (53) for enabling exhaust gases from the engine to be conducted to the turbine (40) in order to rotate the turbine (40), a chamber (96) which surrounds the turbine (40) and which receives the exhaust gases from the second inlet (53) before the exhaust gases are conducted to the turbine (40), a bearing assembly (82) for permitting the rotation of the turbine (40), and a control system (5, 10) for controlling the speed of the turbine (40), the control system (5, 10) having an exhaust gas sealing system (8, 21, 26) for preventing exhaust gas leakage from the turbocharger apparatus (1), and the exhaust gas sealing system (8, 21, 26) being such as to allow expansion of parts within the exh
