給装置。In a tarpo supercharging system for an engine, the exhaust gas introduction portion of the turbine housing is provided with at least two inlets separated by a partition wall, and each of the inlets is equipped with a valve capable of opening and closing in order to vary the supercharging capacity. A valve control mechanism is provided to keep the valve device closed when the pressure on the upstream side of the valve device is below the required pressure, and to open one of the above device when the pressure rises above the required pressure. A variable capacity turbocharger characterized by:
