The improvements are made in the turbine scroll and the turbine blades. The scroll structure for the radial turbines is characterized by the foregoing scroll having a scroll width ratio between the width in the radial direction (&Dgr;R) and the width in the direction of the rotation (B) ranging from &Dgr;R/B=0.3 to 0.7. It is further characterized by the configuration in which the turbine blades have cut-away areas at the blade corners by a prescribed amount, which are provided on the inlet edge at the shroud side and hub side where the operating gas flo...
1. A structure of a turbine scroll used in a radial turbine in which operating gas flows through a vortex-shaped scroll formed inside a turbine casing to turbine blades of a turbine rotor positioned inside said turbine scroll, flowing into said blades in a radial direction to rotate the turbine rotor before flowing out, in the axial direction, wherein said turbine scroll has a scroll width ratio &Dgr;R/B between the width in the radial direction (&Dgr;R) and the width in the direction of the rotation (B) which ranges between 0.3 and 0.7, and wherein said...
