ABSTRACT:
A turbine casing for superchargers having a baffle wall formed therewithin with the inclination inclined at about 30.degree. to 35.degree. relative to a perpendicular to the axis of a turbine impeller so that the inside of the turbine casing is formed into two flow paths where the exhaust pressure wave is passed through. One of the flow paths has on the side wall thereof opposite to the baffle wall an inclined surface inclined at about 10.degree. to 15.degree. relative to the perpendicular in an opposite direction to the inclination of the baffle wall. The other flow path has on the side surface thereof opposite to the baffle wall an inclined surface inclined at about 55.degree. to 60.degree. relative to the perpendicular in the same direction as the inclination of the baffle wall. Each flow path is uniform in cross section throughout its entire volute.
