Abstract
A turbocharger includes a turbine impeller, a turbine housing which includes a scroll portion and a discharge port, a bypassing passage portion which guides a working fluid from the scroll portion to the discharge port, and a valve portion which controls the inflow of the working fluid to the bypassing passage portion. The hub side scroll is formed so that a cross-sectional area of a passage is larger than that of a shroud side scroll. The valve portion includes a hub side valve which controls the inflow of the working fluid from the hub side scroll to the bypassing passage portion and a shroud side valve which controls the inflow of the working fluid from the shroud side scroll to the bypassing passage portion. An operation of opening and closing the hub side valve is independent from an operation of opening and closing the shroud side valve.
