摘要
The volute (51) is used as a connection between the exhaust of a combustion engine and a gas turbocharger (50). It has a cross section for the gas passage which decreases progressively in order to ensure the gas velocity remains constant. This decrease in area is linear along the circumference of the volute average diameter, being a maximum at the input and nil at the outlet. The height (h) of the fan blades (53) for the turbine wheel (52) can also be modified to vary the angle of incidence for the gas on the wheel.
