とする可変容量ラジアルタービン。The turbine scroll is configured with a spiral-shaped main exhaust passage and an auxiliary exhaust passage arranged in parallel, and only the main exhaust passage is opened toward the inlet of the turbine rotor, and the main exhaust passage and the auxiliary exhaust passage are The turbine scroll is communicated with each other through a communication section provided along the outer circumference of the turbine scroll, and a valve for making the area of the auxiliary exhaust passage variable is provided on the upstream side of the position where the communication section is provided in the auxiliary exhaust passage. The variable displacement radial turbine is characterized in that the main exhaust passage and the auxiliary exhaust passage communicate with each other on the upstream side immediately before the valve.
