摘要： Apparatus for driving a turbosupercharger for an internal combustion engine wherein a negative pressure is generated by accelerating the exhaust gas flow. A turbine (40) is driven by the negative pressure generator (30) and a supercharging turbine (50) is operated by the turbine (40), so that as the suction air is pressurized beforehand, the energy of the exhaust gas flow acts on the turbine (40) by connecting the inlet of the turbine (40) to an exhaust system pipe (20). A low-pressure suction air flow acts on the downstream side of the turbine. In this way, the exhaust gas flow discharged to the turbine outlet is absorbed, and the turbine (40) is driven by the energy of the exhaust gas which flows through the exhaust system pipe (20) as well as by suction force of a powerful negative pressure, which is generated separately. A negative-pressure generator (30) is provided at the downstream end of the exhaust system pipe to generate the suction force.
